construct an array with UIImageView objects in ViewController

Question

In my ViewController, I have three UIImageView objects which are IBOutlet connections as well:

class ViewController: UIViewController {
   @IBOutlet weak var myImg1: UIImageView!
   @IBOutlet weak var myImg2: UIImageView!
   @IBOutlet weak var myImg3: UIImageView!

   //ERROR: Instance member 'myImg1' cannot be used by type 'ViewController'
   var myImgArr:[UIImageView] = [myImg1, myImg2, myImg3]
   ...
}

I try to put all the three UIImageView objects into an array myImgArr , but I got complier error : Instance member 'myImg1' cannot be used by type 'ViewController' , why? how to get rid of this error?

Answer 1

The problem is that you're accessing self before the class was initialised.

you can define it like this: var myImgArr:[UIImageView]

and then in the init method you can do myImgArr = [myImg1, myImg2, myImg3]
