How to display more copies of an object? - ios

Question

Objective
I need my app to display multiple instances of a UIImageView. In other words, the app should take a UIImageView and display it more times inside a view. The new UIImageViews remain identical, only their position in the view changes.
Code
To do so, I firstly declare a UIImageView:
let myImage = UIImage(named: "house")
let myImageView = UIImageView(image: myImage)
myImageView.frame = CGRectMake(view.frame.size.width/2, view.frame.size.height/2, 100, 100)
I then use a for-loop to repeat the image repetition.
for (var i = 0; i != 10; i++) {
// Distribuite UIIMageViews here
self.view.addSubview(myImageView)
}
Though, I seem to find no way to copy a UIImageView and display it more times. Declaring more than one UIImageView sounds like an inefficient solution to me.
Question
Is there any way to display an object (UIImageView) multiple times by declaring it just once?

Answer 1

Since UIImageView doesn't conform to the NSCopying protocol, you will have to do the copy yourself: instantiate a new UIImageView and copy manually each property you think important from the original to the new one.
The following example is creating 10 new images based on the original one. They are just copying the UIImage, but you can complete it and copy the properties you need:
let myImage = UIImage(named: "house")
let myImageView = UIImageView(image: myImage)
myImageView.frame = CGRectMake(view.frame.size.width/2, view.frame.size.height/2, 100, 100)
self.view.addSubview(myImageView)
for (var i = 0; i != 10; i++) {
var newImageView = UIImageView(image: myImageView.image)
newImageView.frame = // yourNewFrame
// Copy any else properties you need from the original image
self.view.addSubview(newImageView)
}
