UI09-UIView视图添加圆角效果

1、        创建工程，编写代码：

- (void)viewDidLoad {

    [super viewDidLoad];

    //读取一张图片

    UIImage *img = [UIImage imageNamed:@"pic"];

   //将该图片添加到图像视图

    UIImageView *imgView = [[UIImageView alloc] initWithImage:img];

//   CGRectrect = CGRectMake(60, 60, 200, 200);

    imgView.frame = CGRectMake(60, 60, 200, 200);

   //设置图像图层圆角半径大小

    imgView.layer.cornerRadius = 100;

   //设置图像视图层的遮罩盖属性，进行边界裁切

    imgView.layer.masksToBounds = YES;

    [self.view addSubview:imgView];}

 

运行效果：
