Keen IO iOS SDK

Important: Starting in version 3.5.0, the variable maxAttempts was renamed to maxEventUploadAttempts to avoid any confusion with the query functionality for limiting failed attempts.

Important: Starting in version 3.3.0, you'll need to add the SystemConfiguration framework to your project. Check the "Build Settings" section for more information.

The Keen IO iOS client is designed to be simple to develop with, yet incredibly flexible. Our goal is to let you decide what events are important to you, use your own vocabulary to describe them, and decide when you want to send them to Keen IO.

While the name of this repo implies that this SDK is strictly for iOS, it can also be used in Mac OS applications by using the Cocoa version as outlined below. The code base is the same, but the build targets are different. :)

Installation

Installing the client should be a breeze, and there are 3 different ways to do it: Carthage, CocoaPods, and Binary. If you run into any problems, please let us know by opening an issue on this repository or sending us an email at [email protected]!

Carthage

If you're using Carthage, add the following to your Cartfile:

github "keenlabs/KeenClient-iOS"

After that, just run carthage update and drag and drop the frameworks in the newly created Carthage/Build folder to the "Linked Frameworks and Libraries" in your project "General" settings tab.

Also, follow the instructions on step 4 found here to work around a bug when submitting to the App Store.

CocoaPods

If you're using CocoaPods, add the following to your Podfile:

pod 'KeenClient'

Then run:

pod install

Universal Binary

You can check the latest version of the binary in our release page here.

While we think the universal binary makes things really easy, we love to be transparent. We love feedback, especially in the form of pull requests. :)

Download

Cocoa
iOS

Uncompress and Add to Xcode

Uncompress the ZIP file for the platform you're using, and drag the folder into your Xcode project. (KeenClient-Cocoa for Cocoa, and KeenClient for iOS).

Swift

Add a header file “ProjectName-Bridging-Header.h”. In the bridging header file, add:

// If you're using the binary
#import “KeenClient.h”

// If you're using Carthage
#import <KeenClient/KeenClient.h>

In Build Settings, set the "Objective-C Bridging Header” section to your newly-created bridging header file ProjectName-Bridging-Header.h.

Build Settings

Make sure to add the following libraries in the "Link Binary with Libraries" section:

CoreLocation.framework
SystemConfiguration.framework

Also enable the "-ObjC" linker flag under "Other Linker Flags".

Voila!

Usage

To use this client with the Keen IO API, you have to configure your Keen IO Project ID and its access keys (if you need an account, sign up here - it's free).

Register Your Project ID and Access Keys

Register the KeenClient shared client with your Project ID and access keys. The recommended place to do this is in one of your application delegates like so:

Objective C

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
	[KeenClient sharedClientWithProjectID:@"your_project_id" andWriteKey:@"your_write_key" andReadKey:@"your_read_key"];
	return YES;
}

Swift

func application(_ application: UIApplication,
			didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool
{
	let client: KeenClient
	client = KeenClient.sharedClient(withProjectID: "your_project_id",
																	 andWriteKey: "your_write_key",
																	 andReadKey: "your_read_key");
	return true
}

The write key is required to send events to Keen IO. The read key is required to do analysis on Keen IO.

[KeenClient sharedClientWithProjectID: andWriteKey: andReadKey:] does the registration. From now on, in your code, you can just reference the shared client by calling objc [KeenClient sharedClient].

Add Events

Add events to track. Here’s a very basic example for an app that includes two tabs. We want to track when a tab is switched to.

Objective C

- (void)viewWillAppear:(BOOL)animated
{
  	[super viewWillAppear:animated];

  	NSDictionary *event = [NSDictionary dictionaryWithObjectsAndKeys:@"first view", @"view_name", @"going to", @"action", nil];
  	[[KeenClient sharedClient] addEvent:event toEventCollection:@"tab_views" error:nil];
}

Swift

override func viewWillAppear(_ animated: Bool)
{
	super.viewWillAppear(animated)
	let event = ["view_name": "first view Swift", "action": "going to"]
	do {
		try KeenClient.shared().addEvent(event, toEventCollection: "tab_views")
	} catch _ {
	};	
}

The idea is to first create an arbitrary dictionary of JSON-serializable values. We support:

NSString, NSNumber, NSDate, NSDictionary, NSArray, and BOOL

The JSON spec doesn’t include anything about date values. At Keen, we know dates are important to track. Keen sends dates back and forth through its API in ISO-8601 format. KeenClient handles this for you.

Keys must be alphanumeric, with the exception of the underscore (_) character, which can appear anywhere but the beginning of the string. For example, “view_name” is allowed, but “_view_name” is not.

Add as many events as you like. KeenClient will cache them on disk until you’re ready to send them.

KeenClient will automatically stamp every event you track with a timestamp. If you want to override the system value with your own, use the following example. Note that the “timestamp” key is set in the header properties dictionary.

Objective C

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

   	NSDictionary *event = [NSDictionary dictionaryWithObjectsAndKeys:@"first view", @"view_name", @"going to", @"action", nil];
    NSDate *myDate = [NSDate date];
    KeenProperties *keenProperties = [[KeenProperties alloc] init];
   	keenProperties.timestamp = myDate;
    [[KeenClient sharedClient] addEvent:event
           	         withKeenProperties:keenProperties
       	              toEventCollection:@"tab_views"
   	                              error:nil];
}

Swift

override func viewWillAppear(animated: Bool) 
{
	super.viewWillAppear(animated)
        
	let event = ["view_name": "first view Swift", "action": "going to"]
	let keenProps: KeenProperties = KeenProperties()
	keenProps.timestamp = NSDate() as Date!;
	do {
		try KeenClient.shared().addEvent(event, with: keenProps, toEventCollection: "tab_views")
	} catch _ {
	}
}

Global Properties

Now you might be thinking, “Okay, that looks pretty easy. But what if I want to send the same properties on every event in a particular collection? Or just every event, period?” We’ve got you covered through something we call Global Properties.

Global properties are properties which are sent with every event. For example, you may wish to always capture device information like OS version, handset type, orientation, etc.

There are two ways to handle Global Properties - one is more simple but more limited, while the other is a bit more complex but much more powerful. For each of them, after you register your client, you’ll need to set an Objective-C property on the KeenClient instance you’re using.

Dictionary-based Global Properties

For this, the Objective-C property is called globalPropertiesDictionary. The property’s value will be an NSDictionary that you define. Each time an event is added, the client will look at the value of this property and add all its contents to the user-defined event. Use this if you have a bunch of static properties that you want to add to every event.

Here's an example using a dictionary:

Objective C

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    KeenClient *client = [KeenClient sharedClient];
   	client.globalPropertiesDictionary = @{@"some_standard_key": @"some_standard_value"};
}

Swift

func applicationDidBecomeActive(application: UIApplication) 
{
	KeenClient.shared().globalPropertiesDictionary = 
					        ["some_standard_key" : "some_standard_value"]
}

If there are two properties with the same name specified in the user-defined event and the global properties, the user-defined event’s property will be the one used.

Block-based Global Properties

For this, the Objective-C property is called globalPropertiesBlock. The property’s value will be a block that you define. Every time an event is added, the block will be called. The client expects the block to return an NSDictionary consisting of the global properties for that event collection. Use this if you have a bunch of dynamic properties (see below) that you want to add to every event.

Here’s an example using blocks:

Objective C

- (void)applicationDidBecomeActive:(UIApplication *)application
{
   	KeenClient *client = [KeenClient sharedClient];
    client.globalPropertiesBlock = ^NSDictionary *(NSString *eventCollection) {
   	    if ([eventCollection isEqualToString:@"apples"]) {
       	    return @{ @"color": @"red" };
        } else if ([eventCollection isEqualToString:@"pears"]) {
   	        return @{ @"color": @"green" };
        } else {
   	        return nil;
        }
   	};
}

Swift

- (void)applicationDidBecomeActive:(UIApplication *)application
{
		KeenClient.shared().globalPropertiesBlock =
			{(eventCollection : String?) -> [AnyHashable: Any]? in
					if (eventCollection!.compare("apples") ==
							ComparisonResult.orderedSame)
					{
							return ["color" : "red"]
					} else if (eventCollection!.compare("pears") ==
							ComparisonResult.orderedSame)
					{
							return ["color" : "green"]
					}
					return nil
		};
}

The block takes in a single string parameter which corresponds to the name of this particular event. And we expect it to return an NSDictionary of your construction. This example doesn’t make use of the parameter, but yours could!

Because we support a block here, you can create dynamic global properties. For example, you might want to capture the orientation of the device, which obviously could change at run-time. With the block, you can use functional programming to ask the OS what the current orientation is, each time you add an event. Pretty useful, right?

Another note - you can use both the dictionary property and the block property at the same time. If there are conflicts between defined properties, the order of precedence is: user-defined event > block-defined event > dictionary-defined event. Meaning the properties you put in a single event will always show up, even if you define the same property in one of your globals.

Geo Location

Like any good mobile-first service, Keen supports geo localization so you can track where events happened. This is enabled by default. Just use the client as you normally would and your users will be asked to allow geo location services. All events will be automatically tagged with the current location.

Refreshing Current Location

Every time the app is freshly loaded, the client will automatically ask the device for its current location. It won’t ask again in order to save battery life. You can tell the client to ask the device for location again. Simply call:

Objective C

[[KeenClient sharedClient] refreshCurrentLocation];

Swift

KeenClient.shared().refreshCurrentLocation()

Manually Setting Location

You can also set the location manually. See the following example:

Objective C

NSDictionary *event = [NSDictionary dictionaryWithObjectsAndKeys:@"first view", @"view_name", @"going to", @"action", nil];

KeenProperties *keenProperties = [[KeenProperties alloc] init];
CLLocation *location = [[CLLocation alloc] initWithLatitude:37.73 longitude:-122.47];
keenProperties.location = location;

[[KeenClient sharedClient] addEvent:event withKeenProperties:keenProperties toEventCollection:@"tab_views" error:nil];

Swift

let event = ["view_name": "first view Swift", "action": "going to"]
let keenProps: KeenProperties = KeenProperties()
let location: CLLocation = CLLocation(latitude: 37.73, longitude: -122.47)
keenProps.location = location

do {
    try KeenClient.shared().addEvent(event, with: keenProps, toEventCollection: "tab_views")
} catch _ {
}

Requesting Authorization for Location in iOS 8+

iOS 8 introduced a new method for requesting authorization that requires a few additional steps before location will automatically be appended to your events:

Add one or both of the following keys to your Info.plist file: NSLocationWhenInUseUsageDescription,NSLocationAlwaysUsageDescription
Call the appropriate authorization method to authorize your app to use location services. authorizeGeoLocationWhenInUse and authorizeGeoLocationAlways were both added as of version 3.2.16 of this SDK. authorizeGeoLocationWhenInUse is enabled by default as long as NSLocationWhenInUseUsageDescription is specified in your Info.plist file, so you don't need to call it if you're going the 'When in Use' route. authorizeGeoLocationAlways on the other hand must be called explicitly.

Example:

Objective C

[KeenClient authorizeGeoLocationAlways];
[KeenClient sharedClientWithProjectID:@"your_project_id" andWriteKey:@"your_write_key" andReadKey:@"your_read_key"];

Swift

KeenClient.authorizeGeoLocationAlways()
KeenClient.sharedClient(withProjectID: "your_project_id", andWriteKey: "your_write_key", andReadKey: "your_read_key");

Upload Events to Keen IO

Upload the captured events to the Keen service. This must be done explicitly. We recommend doing the upload when your application is sent to the background, but you can do it whenever you’d like (for example, if your application typically has very long user sessions). The uploader spawns its own background thread so the main UI thread is not blocked.

Objective C

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    UIBackgroundTaskIdentifier taskId = [application beginBackgroundTaskWithExpirationHandler:^(void) {
        NSLog(@"Background task is being expired.");
    }];

    [[KeenClient sharedClient] uploadWithFinishedBlock:^(void) {
        [application endBackgroundTask:taskId];
    }];
}

Swift

- (void)applicationDidEnterBackground:(UIApplication *)application
{
		let taskId : UIBackgroundTaskIdentifier = application.beginBackgroundTask(expirationHandler: {() -> Void in
				NSLog("Background task is being expired.")
		});
		KeenClient.shared().upload(finishedBlock: {() -> Void in
				application.endBackgroundTask(taskId)});
}

In this example, the upload is done in a background task so that even once the user backgrounds your application, the upload can continue. Here we first start the background task, start the upload, and then end the background task once the upload completes.

If you want to call upload periodically during your application’s execution, you can do so by simply invoking the uploadWithFinishedBlock method on your KeenClient instance at any point.

Objective C

[[KeenClient sharedClient] uploadWithFinishedBlock:nil];

Swift

KeenClient.shared().upload(finishedBlock: nil)

An important note: it's a best practice to issue a single upload at a time. We make a best effort to reduce the number of threads spawned to upload in the background, but if you call upload many many times in a tight loop you're going to cause issues for yourself.

Limiting Upload Retries

By default, the client will only attempt to upload a given event 3 times -- after that it will be purged from the local queue. You can change this number to your liking by setting the client.maxEventUploadAttempts value:

Objective C

// Set the max upload attempts to 10
[KeenClient sharedClient].maxEventUploadAttempts = 10;

Swift

// Set the max upload attempts to 10
KeenClient.shared().maxEventUploadAttempts = 10

Add-ons

Keen IO can take data you’ve sent and enrich it by parsing the data or joining it with other data sets. This is done through the concept of “add-ons”.

To activate add-ons, you simply add some new properties within the “keen” namespace in your events. Detailed documentation for the configuration of our add-ons is available here.

For example, let's say we want to enable the IP to Geo add-on:

Objective C

KeenClient *client = [KeenClient sharedClient];
client.globalPropertiesDictionary = @{@"keen":
                                         @{
                                           @"addons":@[
                                                       @{
                                                           @"name":@"keen:ip_to_geo",
                                                           @"input":@{
                                                                   @"ip":@"ip_address"
                                                           },
                                                           @"output":@"ip_geo_info"
                                                       }
                                                   ]
                                               },
                                           @"ip_address":[self getIPAddress:YES]
                                         };

Swift

KeenClient.shared().globalPropertiesDictionary = [
	"keen": [
		"addons": [
			[
				"name": "keen:ip_to_geo",
				"input": ["ip" : "ip_address"],
				"output": "ip_geo_info"
			]
		]
	],
	"ip_address": self.getIPAddress(true)
]

In this example, we add a global property for the IP to Geo information that allows us to translate the device's current IP address into the geographical location of the device by using the [self getIPAddress:YES] method.

Note: [self getIPAddress:YES] is a custom method that you'll have to implement for yourself as there's currently no built-in method to obtain the device's IP address. We've had success using a few of the solutions suggested in this post.

Querying

After collecting event data inside your application, you might want to analyze it by running certain queries. You can do so by using the class KIOQuery and the methods KeenClient.runAsyncQuery and KeenClient.runAsyncMultiAnalysisWithQueries.

There's a whole bunch of different queries you can run depending on the questions you're trying to answer. You can find more detailed information in our documentation here, but the list of analysis types is:

Count - Return the total number of events found in a given collection.
Count Unique - Return the number of unique values for a given property.
Minimum - Return the minimum of all numeric values for a given property.
Maximum - Return the maximum of all numeric values for a given property.
Sum - Calculate the sum of all numeric values for a given property.
Average - Calculate the average of all numeric values for a given property.
Median - Calculate the median of all numeric values for a given property.
Percentile - Calculate a given percentile of all numeric values for a given property.
Select Unique - Return a list of all unique values found for a given property.

Besides that, you can also run:

Multi-Analysis - Run multiple analyses with a single request.
Funnels - Track the completion of a sequence of events.

Limiting Query Attempts

Keen IO has rate limits for Queries (more information can be found here. For that reason, and taking into account the long approval process that apps go through, a small error in a query statement or changing your event collection properties could cause your app to hit that query limit and in turn create a bad experience for your users.

By default, the client will only attempt to run a failed query up to 10 times. After that it will only try to run it again after 3600 seconds (1 hour). You can change these numbers to your liking by setting the client.maxQueryAttempts and the client.queryTTL values:

Objective C

[KeenClient sharedClient].maxQueryAttempts = 10;

// Change the default value to 10 minutes
[KeenClient sharedClient].queryTTL = 600;

Swift

KeenClient.shared().maxQueryAttempts = 10

// Change the default value to 10 minutes
KeenClient.shared().queryTTL = 600

Examples

Creating a query is as simple as instantiating a KIOQuery object:

Objective-C:

KIOQuery *countQuery = [[KIOQuery alloc] initWithQuery:@"count" andPropertiesDictionary:@{@"event_collection": @"collection", @"timeframe": @"this_14_days"}];

Swift:

let countQuery: KIOQuery = KIOQuery(query:"count", andPropertiesDictionary:["event_collection": "collection", "timeframe": "this_14_days"])

Let's show a few examples of running different queries. The last parameter of both KeenClient.runAsyncQuery and KeenClient.runAsyncMultiAnalysisWithQueries is a block. To avoid copy+pasting we'll use the same block for all the queries. It is going to print out the results in case of a successful query, or print out the errors in case the query fails:

Objective-C:

// Create block to run after query completes
void (^countQueryCompleted)(NSData *, NSURLResponse *, NSError *) = ^(NSData *responseData, NSURLResponse *returningResponse, NSError *error) {
    NSDictionary *responseDictionary = [NSJSONSerialization
                                        JSONObjectWithData:responseData
                                        options:kNilOptions
                                        error:nil];
    
    NSNumber *result = [responseDictionary objectForKey:@"result"];
    
    if(error || [responseDictionary objectForKey:@"error_code"]) {
        NSLog(@"Failure! 😞 \n\n error: %@\n\n response: %@", [error localizedDescription], [responseDictionary description]);
    } else {
        NSLog(@"Success! 😄 \n\n response: %@", [responseDictionary description]);
    }
};

Swift:

// Create block to run after query completes
let countQueryCompleted = { (responseData: Data?, returningResponse: URLResponse?, error: Error?) -> Void in
    do {
        let responseDictionary: NSDictionary? = try JSONSerialization.jsonObject(with: responseData!, options: JSONSerialization.ReadingOptions.mutableContainers) as? NSDictionary;
        
        if error != nil {
            self.resultTextView.text = "Error! 😞 \n\n error: \(error.localizedDescription)"
        } else if let errorCode = responseDictionary!.object(forKey: "error_code"),
            let errorMessage = responseDictionary!.object(forKey: "message") as? String {
            self.resultTextView.text = "Failure! 😞 \n\n error code: \(errorCode)\n\n message: \(errorMessage)"
        } else {
            let result: NSNumber = responseDictionary!.object(forKey: "result") as! NSNumber
            
            self.resultTextView.text = "Success! 😄 \n\n result: \(result) \n\n response: \(responseDictionary!.description)"
        }
    } catch let error as NSError {
        print("Error: \(error.localizedDescription)")
    }
}

Count Example

Objective-C:

KIOQuery *countQuery = [[KIOQuery alloc] initWithQuery:@"count" andPropertiesDictionary:@{@"event_collection": @"collection", @"timeframe": @"this_14_days"}];
    
[[KeenClient sharedClient] runAsyncQuery:countQuery block:countQueryCompleted];

Swift:

// KIOQuery object containing the query type and properties
let countQuery: KIOQuery = KIOQuery(query:"count", andPropertiesDictionary:["event_collection": "collection", "timeframe": "this_14_days"])

// Run the query
KeenClient.shared().runAsyncQuery(countQuery, block: countQueryCompleted)

Count Unique Example

Objective-C:

KIOQuery *countUniqueQuery = [[KIOQuery alloc] initWithQuery:@"count_unique" andPropertiesDictionary:@{@"event_collection": @"collection", @"target_property": @"key", @"timeframe": @"this_14_days"}];
    
[[KeenClient sharedClient] runAsyncQuery:countUniqueQuery block:countQueryCompleted];

Swift:

let countUniqueQuery: KIOQuery = KIOQuery(query:"count_unique", andPropertiesDictionary:["event_collection": "collection", "target_property": "key", "timeframe": "this_14_days"])

KeenClient.shared().runAsyncQuery(countUniqueQuery, block: countQueryCompleted)

Multi-Analysis Example

Objective-C:

KIOQuery *countQuery = [[KIOQuery alloc] initWithQuery:@"count" andPropertiesDictionary:@{@"event_collection": @"collection", @"timeframe": @"this_14_days"}];
KIOQuery *countUniqueQuery = [[KIOQuery alloc] initWithQuery:@"count_unique" andPropertiesDictionary:@{@"event_collection": @"collection", @"target_property": @"key", @"timeframe": @"this_14_days"}];

// Optionally set a name for your queries, so it's easier to check the results
[countQuery setQueryName:@"count_query"];
[countUniqueQuery setQueryName:@"count_unique_query"];

[[KeenClient sharedClient] runAsyncMultiAnalysisWithQueries:@[countQuery, countUniqueQuery] block:countQueryCompleted];

Swift:

let countQuery: KIOQuery = KIOQuery(query:"count", andPropertiesDictionary:["event_collection": "collection", "timeframe": "this_14_days"])
let countUniqueQuery: KIOQuery = KIOQuery(query:"count_unique", andPropertiesDictionary:["event_collection": "collection", "target_property": "key", "timeframe": "this_14_days"])

// Optionally set a name for your queries, so it's easier to check the results
countQuery.queryName = "count_query"
countUniqueQuery.queryName = "count_unique_query"

KeenClient.shared().runAsyncMultiAnalysis(withQueries: [countQuery, countUniqueQuery], block: countQueryCompleted);

Funnel Example

Objective-C:

KIOQuery *funnelQuery = [[KIOQuery alloc] initWithQuery:@"funnel" andPropertiesDictionary:@{@"timeframe": @"this_14_days", @"steps": @[@{@"event_collection": @"user_signed_up",
            @"actor_property": @"user.id"},
          @{@"event_collection": @"user_completed_profile",
            @"actor_property": @"user.id"}]}];
    
[[KeenClient sharedClient] runAsyncQuery:funnelQuery block:countQueryCompleted];

Swift:

let funnelQuery: KIOQuery = KIOQuery(query:"funnel", andPropertiesDictionary:["timeframe": "this_14_days", "steps": [["event_collection": "user_signed_up", "actor_property": "user.id"], ["event_collection": "user_completed_profile", "actor_property": "user.id"]]])

KeenClient.shared().runAsyncQuery(funnelQuery, block: countQueryCompleted)

Debugging

KeenClient code does a lot of logging, but it’s turned off by default. If you’d like to see the log lines generated by your usage of the client, you can enable logging easily:

Objective C

[KeenClient enableLogging];

Swift

KeenClient.enableLogging()

Just put this at any point before you use KeenClient. A good place is in your application delegate.

To disable logging, simply call:

Objective C

[KeenClient disableLogging];

Swift

KeenClient.disableLogging()

FAQs

Q: What happens when the device is offline? Will events automatically be sent when the device connects to wifi again?

A: Our SDK handles offline data collection and have built-in limits to prevent too much data from building up. We also handle re-posting events so that you don't have to worry about this.

Here's how it works. You specify when events should be uploaded to Keen (e.g. when the app is backgrounded).

If your player is offline when that happens, their data will be collected on the device and it will not be posted to Keen IO. However, the next time they trigger the code that send events (e.g. backgrounding the app again) all the data from the previous sessions will also be posted (the timestamps will reflect the times the events actually happened).
