An image view object provides a view-based container for displaying either a single image or for animating a series of images. For animating the images, the UIImageView class provides controls to set the duration and frequency of the animation. You can also start and stop the animation freely.
You specify the animation images by setting the animationImages property of the UIImageView object:
imageView.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"blue"],
[UIImage imageNamed:@"green"],
[UIImage imageNamed:@"orange"],
nil];

We specify the duration of the animation by setting the animationDuration property:
imageView.animationDuration = 3.0f;

We can start or stop animating the images by sending startAnimating or stopAnimating messages to the image view object:
[imageView startAnimating];
or
[imageView stopAnimating];

All images associated with a UIImageView object should use the same scale. If your application uses images with different scales, they may render incorrectly.
