Subclass of UIView, can't set it's own layer.cornerRadius?

Question

I have subclassed UIVIew to make my custom view.

-(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?

Answer 1

include QuartzCore Framework

#import <QuartzCore/QuartzCore.h>

Also include this framework in your project.

你有没有尝试过：

self.layer.cornerRadius = 8;
