Giving UIView rounded corners

My login view has a subview which has a UIActivityView and a UILabel saying "Signing In…". This subview has corners which aren't rounded. How can I make them round?

Is there any way to do it inside my xib?

Try this

#import <QuartzCore/QuartzCore.h> // not necessary for 10 years now  :)

...

view.layer.cornerRadius = 5;
view.layer.masksToBounds = true;

Note: If you are trying to apply rounded corners to a UIViewController 's view, it should not be applied in the view controller's constructor, but rather in -viewDidLoad , after view is actually instantiated.

You can also use the User Defined Runtime Attributes feature of interface builder to set the key path layer.cornerRadius to a value. Make sure you include the QuartzCore library though.

This trick also works for setting layer.borderWidth however it will not work for layer.borderColor as this expects a CGColor not a UIColor .

You will not be able to see the effects in the storyboard because these parameters are evaluated at runtime.

Now you can use a swift category in UIView (code bellow the picture) in with @IBInspectable to show the result at the storyboard (If you are using the category, use only cornerRadius and not layer.cornerRadius as a key path.

extension UIView {
    @IBInspectable var cornerRadius: CGFloat {
        get {
            return layer.cornerRadius
        }
        set {
            layer.cornerRadius = newValue
            layer.masksToBounds = newValue > 0
        }
    }
}
