A super simple UIAlertView category adding block syntax for button actions.

Rationale

Yes, I know this has been done hundreds of times by many people and in many ways. I wrote this for a couple reasons. First, with iOS 7 I'm generally happy with the default appearance and functionality of UIAlertView so why use a completely custom alert? Second, though there are lots of other implementations of this concept, I wasn't happy with any of the rest. They were either too heavyweight, had a poor API, or sketchy implementation. Lastly, why, why, why, hasn't Apple updated the antiquated delegate interface for UIAlertView yet?

Installing

If you're using CocoPods it's as simple as adding this to your Podfile:

pod 'GRKAlertBlocks', '~> 1.0.1'

Documentation

Use as you would normally use UIAlertView, but instantiation is now a class level message, and adding a button can now take a block to be executed when tapped.

UIAlertView *alert = [UIAlertView alertWithTitle:@"Title" message:@"Message"];
[alert addButtonWithTitle:@"Foo" handler:^{
    NSLog(@"Foo!");
}];
[alert addButtonWithTitle:@"Bar" handler:^{
    NSLog(@"Bar!");
}];
[alert show];

NOTE: If you set your own delegate on the alert, no handler blocks will be called.

Additional documentation is available in GRKAlertBlocks.h.
