Objective-C class time delay?

Question

I was wondering if anyone knows of a class in objective-C that stops/delays the application at a specified amount of time during runtime? I've already looked at the Time Manager and NSTimer and don't see how I could possibly put a delay in there. I've never used these two classes before though, so maybe someone else has and could give me a tip? Thanks!

Answer 1

It really depends what you mean by "stops/delays the app." If you have a single threaded app you can just use anyone of the various sleep calls (usleep, sleep, nanosleep, etc). That is probably not what you want though, because it will just result in a hung UI for the user, and won't stop any background threads.

To actually give a decent answer it is probably necessary to know what you are actually trying to do. Are you waiting for something, polling a resource, etc?
