NSTimer Troubles

Hi all,

Could someone explain to me how to make an NSTimer and start/stop it?

I've tried:

Code:

timer = [NSTimer timerWithTimeInterval:0.5 target:self selector:@selector(updateCountdown) userInfo:nil repeats:YES];

Code:

if(countdownTime < 1) [timer invalidate];

But it won't enter the method/function "updateCountdown". I'm not sure why the selector isn't working, but could someone please give me some tips?

timerWith... doesn't return a scheduled timer. scheduledTimerWith... does. I've made that mistake before, so many wasted hours looking for the problem.

Again, that was a perfect response. I would never have seen that difference. Thank you!
