什么是Java + Swing的事件调度线程的Objective-C + Cocoa等价物？

Question

I'm an experienced Java Swing programmer. We have a mantra: "all UI work must be performed on the Event Dispatch Thread (EDT)."

I assume Cocoa has a similar mantra. What is Cocoa's equivalent of Java's EDT? And how do I make a block of code run on that equivalent?

If it is significant, I'm using Cocoa for an OS X app , not for an iOS ap.

Answer 1

dispatch_async(dispatch_get_main_queue(), ^{
    //UI updates on main thread
});
