I am trying to make a circle UIImageView
, and it works. Below is the way I use to make it:
[self.pic.layer setMasksToBounds:YES]; [self.pic.layer setCornerRadius:50.0];
I would like to add some shadow to the UIImageView
. The below code does add some shadow to my image view, however, the image view changes back to square shape. Can someone give me some pointers to solve this problem? Below is the code I use to add the shadow:
self.pic.layer.shadowColor = [UIColor purpleColor].CGColor; self.pic.layer.shadowOffset = CGSizeMake(0, 1); self.pic.layer.shadowOpacity = 1; self.pic.layer.shadowRadius = 1.0; self.pic.clipsToBounds = NO;
Add subview with the same color which will be centered on the parent and will be with several pixels smaller. Like this you will have space from each side of the parent. On the parent turn on clipping subviews and add shadow to the inner view. Like this, you can have an inner shadow.
Use the CALayer
's shadowPath
property and add a UIBezierPath
with rounded rect
self.pic.layer.shadowPath = [UIBezierPath bezierPathWithRoundedRect:self.pic.frame cornerRadius:50.0].CGPath;
EDIT
For a square-ish image view this technique does not work directly because, as you said, the image view goes back to square. Reason: You set clipsToBounds = NO
to show the shadow which removes the clipping for corner radius, where imageView
is subview of container
.
Workaround:
Add your imageview in a container view and then apply the layer shadow to this container. Following is the code I tried.
[self.imageView.layer setCornerRadius:60.0]; [self.imageView.layer setMasksToBounds:YES]; self.imageView.clipsToBounds = YES; self.container.backgroundColor = [UIColor clearColor]; self.container.layer.shadowColor = [UIColor blackColor].CGColor; self.container.layer.shadowOffset = CGSizeMake(5,15); self.container.layer.shadowOpacity = 0.5; self.container.layer.shadowRadius = 2.0; self.container.layer.shadowPath = [UIBezierPath bezierPathWithRoundedRect:self.container.bounds cornerRadius:100.0].CGPath;
The resultant effect is as shown in the screenshot,
