I’ve been doing a bit more iPhone development recently and one of the challenges we encountered was to control the background color of a UIView programmatically. Now this is a pretty simple thing to do until you decide you also want to round the corners of that view.
One option is of course to use an image as a background but this wouldn’t allow us to programmatically change the background color of the UIView.
After a bit of digging I finally came across the method
cornerRadius delcared as the following:
@property CGFloat cornerRadius
The corner radius is a property of the layer which is a CALayer. In order to use this though you must be using iPhone SDK Version 3.0 or above and you must include
Another tip was that the corner radius does not work until you set
masksToBounds to true. With all of this combined the following snippet should allow you to create rounded rectangles on your UIViews.
//Includes #import "QuartzCore/QuartzCore.h" //To set the rounded corners self.layer.masksToBounds = YES; self.layer.cornerRadius = 5.0;
