Example

You can animate a UIImageView by quickly displaying images on it in a sequence using the UIImageView's animation properties:

imageView.animationImages = [UIImage(named: "image1")!,
                             UIImage(named: "image2")!,
                             UIImage(named: "image3")!,
                             UIImage(named: "image4")!,
                             UIImage(named: "image5")!,
                             UIImage(named: "image6")!,
                             UIImage(named: "image7")!,
                             UIImage(named: "image8")!] 
imageView.animationDuration = 0.3
imageView.animationRepeatCount = 1

The animationImages property is an Array of UIImages that is run through from top to bottom when the animation is triggered.

The animationDuration property is a Double saying how many seconds the animation will run for.

The animationRepeatCount property is an Int that says how many times the animation will run.

To start and stop the animation, you can call the appropriate methods to do so:

imageView.startAnimating()
imageView.stopAnimating()

There is method isAnimating() which returns a Boolean value indicating whether the animation is running at a moment or not.

Please note that this's not a very efficient way to create animations: it's quite slow and resource-consuming. Consider using Layers or Sprites for better results
