How can I make a button have a rounded border in Swift?

Question

I\'m building an app using swift in the latest version of Xcode 6, and would like to know how I can modify my button so that it can have a rounded border that I could adjust mys

Answer 1

I have created a simple UIButton sublcass that uses the tintColor for its text and border colours and when highlighted changes its background to the tintColor.

class BorderedButton: UIButton {

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    layer.borderWidth = 1.0
    layer.borderColor = tintColor.CGColor
    layer.cornerRadius = 5.0
    clipsToBounds = true
    contentEdgeInsets = UIEdgeInsets(top: 8, left: 8, bottom: 8, right: 8)
    setTitleColor(tintColor, forState: .Normal)
    setTitleColor(UIColor.whiteColor(), forState: .Highlighted)
    setBackgroundImage(UIImage(color: tintColor), forState: .Highlighted)
}
}

This makes use of a UIImage extension that creates an image from a colour, I found that code here: https://stackoverflow.com/a/33675160

It works best when set to type Custom in interface builder as the default System type slightly modifies the colours when the button is highlighted.
