我想为UI
ImageView添加白色边框.我尝试了以下,但它不起作用：
UIImage *image = [UIImage imageNamed:imagePath];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
CGRect rect = imageView.frame;
rect.size.width = rect.size.width + 1; // create white right border
[imageView setBackgroundColor:[UIColor whiteColor]];
imageView.frame = rect;
[myViewView addSubview:imageView];
解决方法
我现在就这样做了
CALayer *sublayer = [CALayer layer];
sublayer.backgroundColor = [UIColor whiteColor].CGColor;
sublayer.frame = CGRectMake(imageView.bounds.size.width,1,imageView.frame.size.height);
[imageView.layer addSublayer:sublayer];
