添加圆角到的UIImageView和显示投影效果(Add Round Corner to UIIma

我这里有同样的问题为纽带：不能添加一个拐角半径和阴影

如果我把maskToBounds = YES，我得到的圆角，但没有阴影如果我把maskToBounds = NO，我得到的影子，但没有圆角。

然后我也跟着在上面的链接的指令，设置maskToBounds = NO“而是设定圆角半径，并设置有圆角的矩形阴影的贝塞尔路径，保持两个相同的半径”。但后来，我没有得到圆角，我也没有得到任何的影子！（无阴影即正方形图像）能否请你帮我出的呢？我不知道我做了什么错。提前致谢。

self.userImageView.backgroundColor = [UIColor redColor]; 
self.userImageView.clipsToBounds = NO; 
self.userImageView.contentMode = UIViewContentModeCenter; 
self.userImageView.layer.masksToBounds = NO; 

self.userImageView.layer.borderWidth = 1; 
self.userImageView.layer.borderColor = [[UIColor grayColor] CGColor]; 

self.userImageView.layer.shadowOpacity = 1; 
self.userImageView.layer.shadowColor = [[UIColor blackColor] CGColor]; 
self.userImageView.layer.shadowRadius = 8.0f; 
self.userImageView.layer.shadowOffset = CGSizeMake(-3, 0);
self.userImageView.layer.shouldRasterize = YES; 

self.userImageView.layer.shadowPath = [[UIBezierPath bezierPathWithRoundedRect:[self.userImageView bounds] cornerRadius:10.0f] CGPath]; 

[self addSubview:self.userImageView];

不幸的是，我不认为UIImageView的支持圆角和阴影在同一时间。

你可以，但是，请在的UIImageView的超级视图的影子。

CGFloat cornerRadius = 3.0

UIView *container = [[UIView alloc] initWithFrame:aRect];
container.layer.shadowOffset = CGSizeMake(0, 0);
container.layer.shadowOpacity = 0.8;
container.layer.shadowRadius = 5.0;
container.layer.shadowColor = [UIColor redColor].CGColor;
container.layer.shadowPath = [[UIBezierPath bezierPathWithRoundedRect:container.bounds cornerRadius:cornerRadius] CGPath];

self.userImageView.layer.cornerRadius = cornerRadius;
self.userImageView.layer.masksToBounds = YES;
self.userImageView.frame = container.bounds;
[container addSubview:self.userImageView];
[self addSubview:container];
