AHAlertView is a powerful, block-based alternative to UIKit's UIAlertView. It has the following attractive features:
- Block-based button events - no more messy delegate code
UIAppearanceconformance to allow easy skinning of all elements- Dramatic presentation and dismissal animations (tumble, fade, zoom, etc.)
Showing an alert is as simple as creating an alert, adding a button, and calling show:
AHAlertView *alert = [[AHAlertView alloc] initWithTitle:@"Hello, World!" message:@"I'm an alert view!"];
[alert setCancelButtonTitle:@"Dismiss" block:nil];
[alert show];
If a total of two buttons are added, the alert view will lay them out side-by-side:
AHAlertView *alert = [[AHAlertView alloc] initWithTitle:@"Enter Password" message:@"This is a message that might prompt you to do something."];
[alert setCancelButtonTitle:@"Cancel" block:nil];
[alert addButtonWithTitle:@"OK" block:nil];
[alert show];
You can use an alert view to prompt for user input, including secure text for password fields, etc.:
AHAlertView *alert = [[AHAlertView alloc] initWithTitle:@"Enter Password" message:@"[email protected]"];
alert.alertViewStyle = AHAlertViewStyleSecureTextInput;
[alert setCancelButtonTitle:@"Cancel" block:^{
NSLog(@"User canceled the alert instead of entering their password.");
}];
[alert addButtonWithTitle:@"OK" block:^{
NSLog(@"User entered the password: %@", [alert textFieldAtIndex:0].text);
}];
[alert show];
You can use the block you pass in with the button title to perform any action, including setting a custom dismissal animation based on which button was touched:
[alert setCancelButtonTitle:@"Cancel" block:^{
alert.dismissalStyle = AHAlertViewDismissalStyleTumble;
}];
This library is ARC-only, because you should be using ARC. Are you seriously not using ARC yet?
- I think we can all agree a little more documentation would be nice.
- Indeterminate progress style, possibly a determinate one as well.
- Better button layout code
