iPhone SDK: Running a selector after a delay..

Quite often I've needed to run a selector after a certain time interval. Usually what I've done is the following:

[NSTimer scheduledTimerWithTimeInterval:0.0 target:self selector:@selector(doIt:) userInfo:nil repeats:YES];

A shorter and slightly easier method is a selector on NSObject (now that's a base class with a lot of methods if ever I've seen one!)

[self performSelector:@selector(doit) withObject:nil afterDelay:1.0];

If you set afterDelay to be 0.0, you have a quick and easy way of making a selector run once the current run loop has completed.
