Rounding UIImage and adding a border

Question

so I want to show some pictures as annotations on the map. In order to do that I need to add the image property of the MKAnnotationView. I'm using the regular images but I want them to be rounded and with a border. So I found a way to round UIImage and I found the way to add a border to UIImage, but border doesn't seem to add (I'm not actually having the image on the screen, maybe that is the problem?).

I used this answer https://stackoverflow.com/a/29047372/4665643 with a slight modification for border. Namely:

imageView.layer.borderWidth = 1.5
imageView.layer.borderColor = UIColor.whiteColor().CGColor
imageView.clipsToBounds = true

But my image on the map doesn't have any border. Any suggestions ?

Answer 1

imageView.layer.masksToBounds = true
imageView.layer.borderWidth = 1.5
imageView.layer.borderColor = UIColor.white.cgColor
imageView.layer.cornerRadius = imageView.bounds.width / 2

Try this.
