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. Is there a way that I can make an overlay view on the iPhone SDK?

Answer 1

Use the view.layer's cornerRadius property.

#include <QuartzCore/QuartzCore.h>

...

overlayView.layer.cornerRadius = 5.0;

Answer 2

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

Or use view.layer.cornerRadius, as seen in How do I create a round cornered UILabel on the iPhone?.
