ALActionBlocks

ALActionBlocks is an Objective-C category on UIControl, UIBarButtonItem, and UIGestureRecognizer that allows for handling of control events with blocks.

  • Handle control events with blocks
  • Remove blocks for control events
  • Gives you a weak reference to your control in the block
  • Works with all of your existing subclasses of UIControl, UIBarButtonItem, and UIGestureRecognizer

This category was inspired by [Dave DeLong] (https://github.com/davedelong)'s StackOverflow [answer] (http://stackoverflow.com/a/4582061/315074).

Simple Example

#import "ALActionBlocks.h"
// Assuming you have a UIButton named 'button'
[button handleControlEvents:UIControlEventTouchUpInside withBlock:^(id weakControl) {
    NSLog(@"button pressed");
}];

Removing Blocks

[button removeActionBlocksForControlEvents:UIControlEventTouchUpInside];

That's it!

Check out the demo project for more details.

Requirements

ALActionBlocks is compatible with iOS 5.0 and above.
