time=0.0;
finalDemoAppDelegate *appDeleg = (finalDemoAppDelegate *)[[UIApplication sharedApplication] delegate];
appDeleg.timer=[NSTimer scheduledTimerWithTimeInterval: 0.2
target: self
selector: @selector(incrementCounter
userInfo: nil
repeats: YES];
}

-(void)incrementCounter{
time=time+1;
[self updateLabel];

}

I imagine the error in this case is that you are passing the timer a selector for a method which doesn't exist. You are passing @selector(incrementCounter:) - note the colon implying the method takes an argument - where as your method selector will be @selector(incrementCounter).

What a silly mistake is this..
Thanks a lot
