Simple metronome - Play an AIF every x number of milliseconds

Question
I've had a look at the metronome sample given by Apple, however, the sample is too complicated and includes things not needed in my project.
Is there a simple way to make a system sound play every x number of milliseconds?
Solution
A word of warning... NSTimer is not accurate, if timing is important or you're trying to keep a steady beat.
OTHER TIPS
You are going to want to do something like this:
[NSTimer scheduledTimerWithTimeInterval:x target:self selector:@selector(yourMethodHere:) userInfo:nil repeats:YES];
The Apple examples can help with the actual code needed to play the sound file, and NSTimer should be pretty straightforward to learn how to use.
