How to round the corners of a UIView

Paul Hudson    September 15th 2016    @twostraws

All UIView subclasses have the ability to round their corners thanks to their underlying CALayer – that's the bit that handles the actual drawing of your views. To round the corners of a view, use this code:

yourView.layer.cornerRadius = 10

The number you specify is how far the rounding should go, measured in points. This means that if you have a view that's 128x128 points wide and give it a cornerRadius property of 64, it will look like a circle.

Note that some types of view don't have clipsToBounds enabled by default, which means their corners will not round until you enable this property.

Available from iOS 3.2
