Debounce method for Objective C

NSObject+Debounce.h

@interface NSObject (Debounce)

- (void)debounce:(SEL)action delay:(NSTimeInterval)delay;

@end

NSObject+Debounce.m

@implementation NSObject (Debounce)

- (void)debounce:(SEL)action delay:(NSTimeInterval)delay
{
  __weak typeof(self) weakSelf = self;
  [NSObject cancelPreviousPerformRequestsWithTarget:weakSelf selector:action object:nil];
  [weakSelf performSelector:action withObject:nil afterDelay:delay];
}

@end

Here's my fork that adds a podspec file:

To use it as a pod, use this line in your Podfile:

pod 'NSObject+Debounce', :git => 'https://gist.github.com/maxgalbu/bec9cdb035051b0c4197.git'

Awesome. Much shorter and better than my colleague's implementation. I've introduced this to him.
