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

Use the class method + (void)sleepForTimeInterval:(NSTimeInterval)ti

The variable NSTimeInterval is of type double and represents the number of seconds to sleep

// Block for .5 seconds
[NSThread sleepForTimeInterval:.5];
