if repeats: YES]; check like your seconds reaches or greater than 60, invalidate your timer and dismiss your VC

if (seconds >60)
{
[timer invalidate];
[self dismissViewControllerAnimated:YES completion:nil];
}

else call your timer once using repeats: NO];

timer = [NSTimer scheduledTimerWithTimeInterval: 1.0 target:self selector:@selector(updateCountdown) userInfo:nil repeats: NO];

and call the function like

-(void) updateCountdown {
   [timer invalidate];
  [self dismissViewControllerAnimated:YES completion:nil];

}

timer = [NSTimer scheduledTimerWithTimeInterval: 1.0 target:self selector:@selector(updateCountdown:) userInfo:nil repeats: NO]; // set No

-(void) updateCountdown:(NSTimer *)timer
{
    [timer invalidate];
   // dismiss your controller
}
