Trying to set Border of an UIImage

Question

I am new to swift and I am trying to set a black border around my UIImageView but I am unable to do so. This is my code

@IBOutlet weak var flagImage: UIImageView!
var image = UIImage(named: "estonia")

override func viewDidLoad() {
    super.viewDidLoad()

    flagImage.layer.borderColor = UIColor(red: 0.5, green: 0.5, blue: 0.5, alpha: 1.0).CGColor
    flagImage.layer.cornerRadius = 5.0

    flagImage.contentMode = .scaleAspectFit
    flagImage.image = image
 }

Could I get some help on this?

Answer 1

You gave the border color to the imageView but how could you expect to see the color with out any area to fill in. So, the

flagImage.layer.borderWidth = 2 /** as you wish **/

Gives the Area around the imageView of thickness 2 to fill in the color you gave.

Answer 2

Try to add this

Objective-C

flagImage.layer.masksToBounds = YES;

Swift

flagImage.layer.masksToBounds = true
