You can use like:

Declare a NSTimer object on the @interface like NSTimer *aTimer;

-(void)viewDidLoad
{
    aTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(elapsedTime) userInfo:nil repeats:YES];
}

-(void)elapsedTime
{
    static int i = 60;

    label.text = [NSString stringWithFormat:@"%d",i];

    i--;
    if(i<0)
    {
       [aTimer invalidate];
       aTimer = nil;
    }
}

Here label is a IBOutlet UILabel, that is set to interface.
