ios - 为所有 UIImageView 添加圆角

Question

我想为项目中的所有 UIImageView 添加一些圆角。我已经让代码工作了，但我必须将它应用到每张图片上；我应该将 UIImageView 子类化来添加它吗？如果是这样，有人可以给我一些关于如何执行此操作的指示吗？

这是代码

- (void)viewDidLoad {
    [super viewDidLoad];
    NSString *mainpath = [[NSBundle mainBundle] bundlePath];
    welcomeImageView.image = [UIImage imageWithContentsOfFile:[mainpath stringByAppendingString:@"/test.png"]];
    welcomeImageView.layer.cornerRadius = 9.0;
    welcomeImageView.layer.masksToBounds = YES;
    welcomeImageView.layer.borderColor = [UIColor blackColor].CGColor;
    welcomeImageView.layer.borderWidth = 3.0;
    CGRect frame = welcomeImageView.frame;
    frame.size.width = 100;
    frame.size.height = 100;
    welcomeImageView.frame = frame;
}

检查这个 - Rounded Corners on UIImage

图层修改似乎是最好的方法。

UIImageView * roundedView = [[UIImageView alloc] initWithImage: [UIImage imageNamed:@"wood.jpg"]];
// Get the Layer of any view
CALayer * l = [roundedView layer];
[l setMasksToBounds:YES];
[l setCornerRadius:10.0];
