How do I use NSTimer

I’d like to create a timer: When a user clicks a button the timer starts. After (e.g) two seconds the timer stops/resets and an action is performed.

I’ve been looking at NSTimer without any luck finding the right methods to use, and how to set this up the right way.

In advance, thanks for any help!

Answer 1

- (IBAction)buttonPressed:(id)sender
{
    [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(timerExpired) userInfo:nil repeats:NO];
}

- (void)timerExpired
{
    NSLog(@"Your two seconds are up!");
}
