NSObject+GCD

Simple Objective-C wrapper for most used Grand Central Dispatch functions.

Features:

• You can call these methods on any object in your code (I recommend to always use self).
• -performOnMainThread:wait: – execute block on main thread from any other thread
• -performAsynchronous: – execute block in background (to return back to main thread use method mentioned above)
• -performAfter:block: – execute block on the same thread, but after some delay

Examples:

• Background task with completion on Main Thread:

  [self performAsynchronous:^{
      
      // Background Task
      
      [self performOnMainThread:^{
          // Completion on Main Thread
      } wait:NO];
  }];
  

• Delayed execution:

  [player play];
  [self performAfter:3 block:^{
      [player pause];
  }];
