我想为UIImageView添加白色边框。我尝试了以下方法,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];

我现在就像

那样做了
        CALayer *sublayer = [CALayer layer];
        sublayer.backgroundColor = [UIColor whiteColor].CGColor;
        sublayer.frame = CGRectMake(imageView.bounds.size.width, 0, 1, imageView.frame.size.height);
        [imageView.layer addSublayer:sublayer];

您可以创建一个大于UIImage视图的UIView,并将图像视图的框架设置为0,0,宽度+ 1,高度,这将添加额外的边。
