Rounded corners in button

How can I add corner radius?

2 Answers

Connect your button to your view controller through an IBOutlet. In viewDidLoad() you can give your button a corner radius.

For example:

button.backgroundColor = UIColor.blueColor()
button.layer.cornerRadius = 5
button.layer.borderWidth = 1
button.layer.borderColor = UIColor.blackColor().CGColor

You would have to make a button with rounded corners in Photoshop or Illustrator.
