How to add multiple UIImageView programatically? - arrays

Question

I'm struggling to get all the coupons (UIImage) to show up. For example, I have 3 coupons, when I run my code, it keeps on showing up the 3rd coupon's image only. How come it doesn't show the first 2? Thanks in advance.
override func viewDidLoad() {
var i: Int = 0
super.viewDidLoad()
self.view.backgroundColor = UIColor.white
CouponsViewController.PopulateDataCoupons()
i=0
repeat {
let imageName = MyCoupons.siteCoupons[i]//"Coupons1.jpg"
let image = UIImage(named: imageName!)
let imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: 50, y: 50, width: 350, height: 300)
view.addSubview(imageView)
i += 1 }
while (i < MyCoupons.count-1)
}

You are putting each UIImageView object at the same location. Look at this line:
imageView.frame = CGRect(x: 50, y: 50, width: 350, height: 300)
Try changing the x or y coordinate on each iteration to see each one of the images, like this:
let height = 350
i = 0
repeat {
let imageName = MyCoupons.siteCoupons[i]//"Coupons1.jpg"
let image = UIImage(named: imageName!)
let imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: 50, y: i * height, width: 350, height: height)
view.addSubview(imageView)
i += 1
}
while (i < MyCoupons.count - 1)
Update:
As #Mick MacCallum points out. You should take the UIImageView's height into consideration. See the changes above.
