Question

So I’ve seen it everywhere in apps/games and other things its when you score or you get game over and the score number adds up to your score from zero. I want it so in about 1 second a label goes from the text: 0 to and integer that is stored with the players score.

Answer 1

I would go by using an NSOperation that sleeps and add the points (actually it may work even without sleeping). Something like:

NSInvocationOperation *op = [[NSInvocationOperation alloc] initWithTarget:self 
                                                                 selector:@selector(updateScore)
                                                                   object:nil];
[queue addOperation:[op autorelease]];

-(void)updateScore {
  while (tot < 1.0) {
    displayingScore += score*incr;
    tot += incr;
    // update score label to displayingScore
    [NSThread sleepForTimeInterval:0.05];
  }
}
