Difference between UIImage and UIImageView

Question

What is the difference between UIImage and UIImageView? Can someone explain it with an example?

Answer 1

UIimage is an Object which stores data (Jpg, png...) and UIImageView class which contains UIImage as a property. UIImageView can have multiple UIImages, and UIImage is immutable. That bothered me a long time ago, when you create an image you do:

 var image: UIImageView!

But when you execute that "image" you do

image.image = UIImage.init(named: "image")

Its really easy, you use UIimageView, to create an image with UIImage. UIImage displays the image, and UIImageView is a container for that UIImage.
