How to make an overlay with round edges (iPhone SDK)?

Question

I've just received a lot of good responses to the question about making overlay views. http://stackoverflow.com/questions/2253334/is-there-a-way-that-i-can-make-an-overlay-view-on-the-iphone-sdk

Another question I have is how to make an overlay view have round edges like in the Skype iPhone app or in the Phone.app.

Thanks.

Answer 1

You can use these helper functions and then mask/clip to the resulting CGPath:

Or use view.layer.cornerRadius, as seen in http://stackoverflow.com/questions/510382/how-do-i-create-a-round-cornered-uilabel-on-the-iphone/512402.

Answer 2

Use the view.layer's cornerRadius property.

#include <QuartzCore/QuartzCore.h>

...

overlayView.layer.cornerRadius = 5.0;
