Question

How can I start and stop image animation using button control?

imageView.animationImages = [NSArray arrayWithObjects: 
[UIImage imageNamed:@"p1.jpg"],[UIImage imageNamed:@"p2.jpg"], [UIImage imageNamed:@"p3.jpg"],[UIImage imageNamed:@"p4.jpg"],[UIImage imageNamed:@"p5.jpg"],[UIImage imageNamed:@"p6.jpg"], nil]; 

imageView.animationDuration = 1.00; //1 second
imageView.animationRepeatCount = 0; //infinite

[imageView startAnimating]; //start the animation

Answer 1

Add two buttons using Interface Builder, create two IBAction methods in your controller, connect Touch Up Inside events with the IBActions.
Use [imageView startAnimating] to start, [imageView stopAnimating] to stop.
