How to make thread sleep for seconds in iOS?

Question

In iOS env, is it possible to make current thread sleep for seconds, then execute my code? NSTimer, GDC or any technique is okay for me.

Answer 1

Either

[self performSelector:@selector(YourFunctionName) withObject:(can be Self or Object from other Classes) afterDelay:(Time Of Delay)];`

or

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 1 * NSEC_PER_SEC), 
    dispatch_get_main_queue(), ^{
    //your method 
});
