ALActionBlocks is an Objective-C category on UIControl and UIBarButtonItem 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

This category was inspired by Dave DeLong's StackOverflow answer.

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!
