[英]Subclass of UIView, can't set it's own layer.cornerRadius?
I have subclassed UIVIew to make my custom view.我已经将 UIVIew 子类化来制作我的自定义视图。
-(UIMyMessageView*)init:(NSString*)withMessage
{
[super initWithFrame:messageFrame];
// I Would like to do :
self->layer.cornerRadius = 8; // This doesn't compile
}
Why can't I set my own layer?为什么我不能设置自己的图层?
include QuartzCore Framework包括 QuartzCore 框架
#import <QuartzCore/QuartzCore.h>
Also include this framework in your project.还将此框架包含在您的项目中。
