iOS - Ensure execution on main thread [duplicate]

Question

I want to know how to call my function on the main thread.

How do I make sure my function is called on the main thread?

(this follows a previous question of mine).

Answer 1

This will do it:

[[NSOperationQueue mainQueue] addOperationWithBlock:^ {     //Your code goes in here    NSLog(@"Main Thread Code");  }]; 

Hope this helps!
