我想为 UIImageView 添加一个白色边框。我尝试了以下方法,但没有奏效:
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];
