Delegates are a real pain in the ars. Objective-C blocks rule! This are some category classes of my own to allow easy implementation of the basic iOS frameworks & APIs without the need of using delegation.
Available in Cocoa Pods
pod 'iOSBlocks', '~> 1.0.2', :inhibit_warnings => true
(You should add the 'inhibit_warnings' flag to avoid some existing warnings that must be fixed soon)
Then import the library wherever you need it, or in you application's Prefix.pch file.
#import "iOSBlocks.h"
- (void)pushViewController:(UIViewController *)viewController
animated:(BOOL)animated
onCompletion:(VoidBlock)completion;

And more to come. Enjoy!
Take a look into the sample project. Everything is there.
Enjoy and collaborate if you feel this library could be improved.
