Add Round Corner to UIImageVIew and Display Shadow effect

Question

I have the same problem as the link here: Can't add a corner radius and a shadow

if I put maskToBounds = YES, I get round corners, but no shadow If I put maskToBounds = NO, I get shadow, but no round corners.

Then I followed the instruction in that link above , setting maskToBounds = NO, " but rather set the corner radius and set the bezier path of the shadow with a rounded rect. Keep the radius of the two the same ". But then, I don't get round corners, nor did I get any shadow! (i.e. Square Image without Shadow) Could you please help me out of this? I don't know what did I do wrong. Thanks in advance.

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];

Unfortunately, I don't think UIImageView supports rounded corner and shadow at the same time.

You can, however, make the shadow in the UIImageView's super view.

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];
