如何绕过活动指示器背景的角

Question

I am BRAND NEW to coding. With that said, I have figured out how to put a grey background behind my white activity indicator spinner. Now I want the corners of the background to be rounded. I have searched and searched but I'm not having success.

Here is the code I am using to display the activity indicator and background. If you need more information to help, just ask. I don't really know how to even ask the question. I'm a total rookie.

activityIndicator = UIActivityIndicatorView(frame: CGRectMake(0, 0, 80, 80))

activityIndicator.center = self.view.center

activityIndicator.backgroundColor = (UIColor (white: 0.3, alpha: 0.8))   //create a background behind the spinner

activityIndicator.hidesWhenStopped = true

activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.WhiteLarge

view.addSubview(activityIndicator)

activityIndicator.startAnimating()

UIApplication.sharedApplication().beginIgnoringInteractionEvents()

In answer to your question: you should set the CALayer property cornerRadius to a positive, non-zero value. For example:

activityIndicator.layer.cornerRadius = 10
