推荐答案

通过更改视图支持CALayer的cornerRadius属性，可以在任何视图上实现圆角.要访问这些属性，必须链接到QuartzCore框架.

You can achieve rounded corners on any view by changing the cornerRadius property of the view's backing CALayer. To access these properties, you will have to link against the QuartzCore framework.

然后您可以像这样更改拐角半径:

Then you can change the corner radius like this:

textFieldBackgroundView.layer.cornerRadius = 10;

只需确保将<QuartzCore/QuartzCore.h>添加到您的项目中，然后将其添加#import.

Just make sure to add <QuartzCore/QuartzCore.h> to your project and #import it.
