Objective-C block replacement for some Cocoa Touch APIs depending on delegation.

iOS Blocks

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.

Installation

Available in Cocoa Pods

pod 'iOSBlocks/Cocoa'

You can also install only the subspecs you're interesting in. For example, install only UIKit block APIs:

pod 'iOSBlocks/UIKit'

A few examples

UINavigationController

- (void)pushViewController:(UIViewController *)viewController
                  animated:(BOOL)animated
              onCompletion:(VoidBlock)completion;

&

- (void)popViewControllerAnimated:(BOOL)animated
                     onCompletion:(VoidBlock)completion;
