Several Animations

[XaKaX]

People, when I click in a button, several (5) animations in diferents parts of the view starts showing.

So, I have the folowing code:

       UIImageView *explosion;
        float delay;

        for (int i=0; i<5;i++) { 
            delay = 2.2;
           
            explosion = [[UIImageView alloc] init];
            
            if (i==0) {
                [explosion setFrame:CGRectMake( 115.0f, 50.0f, 100.0f, 200.0f)];
            }
            else if (i==1) {
                [explosion setFrame:CGRectMake( 30.0f, 100.0f, 75.0f, 191.0f)];
            }
            else if (i==2){
                [explosion setFrame:CGRectMake( 240.0f, 100.0f, 75.0f, 191.0f)];
            }
            else if (i==3){
                [explosion setFrame:CGRectMake( 0.0f, 109.0f, 240.0f, 300.0f)];
                delay = 2.8;
            }
            else if (i==4) {
                [explosion setFrame:CGRectMake( 90.0f, 109.0f, 240.0f, 300.0f)];
                delay = 2.8;
            }

            explosion.animationDuration = delay; 
            explosion.animationRepeatCount = 1;

            explosion.animationImages = [arrayOfArrays objectAtIndex:i]; 
            
            [self.view addSubview:explosion];
            [explosion startAnimating];
            
            [self performSelector: @selector(hideAnimation:)
                       withObject:explosion 
                       afterDelay:delay];
          
            [explosion release];
            
        }

arrayOfArrays, is an Array, witch have the Array of images of all the animations. So it is an array of arrays (ex.: in the position 1 have an array of all the images of the first animation, in the position 2 the same, but of the second animation).

It works fine on the simulator.
When I tested it on my iPod, it has a delay (like a lag), and when the 5 animation appears, it is alredy by the end..
But when I click on the button again (the second time), it works fine!


After that, everything runs normally (I can click as many time as I want on the button, that it will show me the 5 animations at the same time normaly, just like on the simulator).

What can I do? What is happening? And why only on the iPod?

Thanks!
