iphone上让方形的图片圆角显示

 

UIImageView * headerImage = [[UIImageView alloc] initWithFrame:CGRectMake(10.0, 10.0, 64.0, 64.0)];
headerImage.image = contactPhoto;
CALayer * layer = [headerImage layer];
[layer setMasksToBounds:YES];
[layer setCornerRadius:10.0];
[layer setBorderWidth:1.0];
[layer setBorderColor:[[UIColor blackColor] CGColor]];
[contactHeader addSubview:headerImage];

 

 

记得头文件:#import <QuartzCore/QuartzCore.h>
