Keypath injection

Hi, i have a AFHTTPRequestOperationManager that comes from pods dependency. AFHTTPRequestOperationManager has property an instance of NSOperationQueue - operationQueue. How i can inject operationQueue maxConcurrentOperationCount property?

So my solution is:

-(id)httpOperationManager{
    return [TyphoonDefinition withClass:[AFHTTPRequestOperationManager class] configuration:^(TyphoonDefinition *definition){
        [definition injectProperty:@selector(operationQueue) with:[self operationQueue]];
    }];
}
-(id)operationQueue{
    return [TyphoonDefinition withClass:[NSOperationQueue class] configuration:^(TyphoonDefinition *definition) {
        [definition injectProperty:@selector(maxConcurrentOperationCount) with:@(1)];
    }];
}

I am trying this implementation, i know that it is worng, because TyphoonInjectionByFactoryReference has no functionality to inject in it something, it is used vice versa.

-(id)httpOperationManager{
    return [TyphoonDefinition withClass:[AFHTTPRequestOperationManager class] configuration:^(TyphoonDefinition *definition){
        id operationQueue = [definition property:@selector(operationQueue)];
        [operationQueue injectProperty:@selector(maxConcurrentOperationCount) with:@(1)];
    }];
}

Hi,
I'm not sure that I understand what you want to do with second code snippet.
I saw your first snippet, it's works and looks clear, but I can't understand the second snippet.
And if first one works for you, then what is the question?

I mean

-(id)httpOperationManager{
    return [TyphoonDefinition withClass:[AFHTTPRequestOperationManager class] configuration:^(TyphoonDefinition *definition){
     [definition injectProperty:@selector(maxConcurrentOperationCount) atKeypath:@"operationQueue.maxConcurrentOperationCount" with:@(1)];
    }];
}

In this case AFHTTPRequestOperationManager inside its init method has simple implementation of NSOperationQueue.

- (instancetype)initWithBaseURL:(NSURL *)url {
    self = [super init];
    if (!self) {
        return nil;
    }
............................................ SOME CODE HERE ............................................
self.operationQueue = [[NSOperationQueue alloc] init];
return self;
}

But what to do, if AFHTTPRequestOperationManager has a complex initialization of NSOperationQueue (this is just a guess)? Because AFHTTPRequestOperationManager is a library i am can not control of it part initialization configuration.
Current solution for me just recreate NSOperationQueue with all settings that i need, and inject it into AFHTTPRequestOperationManager.

Ah, I see that you mean.
Yes, there is no short API for that, but I think it maybe possible via circular reference, try this:

• manager
  inject property queue with: queue
• queue
  with factory: manager selector: operationQueue
  configuration:
  Inject property max operations count here

I'll write the code later today, since I'm from mobile now

Try this code:

- (id)httpOperationManager
{
    return [TyphoonDefinition withClass:[AFHTTPRequestOperationManager class] configuration:^(TyphoonDefinition *definition) {
        [definition injectProperty:@selector(operationQueue) with:[self operationQueue]];
    }];
}

- (id)operationQueue
{
    return [TyphoonDefinition withFactory:[self httpOperationManager] selector:@selector(operationQueue) parameters:nil configuration:^(TyphoonFactoryDefinition *definition) {
        [definition injectProperty:@selector(maxConcurrentOperationCount) with:@(1)];    
    }];
}
