Creating a Shadow for a Uiimageview That Has Rounded Corners

Creating a shadow for a UIImageView that has rounded corners?

If you set clipsToBounds to true, this will round the corners but prevent the shadow from appearing. In order to resolve this, you can create two views. The container view should have the shadow, and its subview should have the rounded corners.

The container view has clipsToBounds set to false, and has the shadow properties applied. If you want the shadow to be rounded as well, use the UIBezierPath constructor that takes in a roundedRect and cornerRadius.

let outerView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
outerView.clipsToBounds = false
outerView.layer.shadowColor = UIColor.black.cgColor
outerView.layer.shadowOpacity = 1
outerView.layer.shadowOffset = CGSize.zero
outerView.layer.shadowRadius = 10
outerView.layer.shadowPath = UIBezierPath(roundedRect: outerView.bounds, cornerRadius: 10).cgPath

Next, set the image view (or any other type of UIView) to be the same size of the container view, set clipsToBounds to true, and give it a cornerRadius.

let myImage = UIImageView(frame: outerView.bounds)
myImage.clipsToBounds = true
myImage.layer.cornerRadius = 10

Finally, remember to make the image view a subview of the container view.

outerView.addSubview(myImage)

The result should look something like this:

UIView with rounded corners and drop shadow?

The following code snippet adds a border, border radius, and drop shadow to v, a UIView:

// border radius
[v.layer setCornerRadius:30.0f];

// border
[v.layer setBorderColor:[UIColor lightGrayColor].CGColor];
[v.layer setBorderWidth:1.5f];

// drop shadow
[v.layer setShadowColor:[UIColor blackColor].CGColor];
[v.layer setShadowOpacity:0.8];
[v.layer setShadowRadius:3.0];
[v.layer setShadowOffset:CGSizeMake(2.0, 2.0)];

Swift 5 Version :

// border radius
v.layer.cornerRadius = 30.0

// border
v.layer.borderColor = UIColor.lightGray.cgColor
v.layer.borderWidth = 1.5

// drop shadow
v.layer.shadowColor = UIColor.black.cgColor
v.layer.shadowOpacity = 0.8
v.layer.shadowRadius = 3.0
v.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)

You can adjust the settings to suit your needs.

Also, add the QuartzCore framework to your project and:

#import

Add Round Corner to UIImageVIew and Display Shadow effect

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];

How to add inner shadow to UIView with rounded corners

It's a trick. You give shadow and border to same view, the shadow will fall inside the view. please make sure the background color of view is clear. use the below code for reference.

yourView.layer.shadowColor = UIColor.gray.cgColor
yourView.layer.shadowOpacity = 0.3
yourView.layer.shadowOffset = CGSize.zero
yourView.layer.shadowRadius = 6
yourView.layer.masksToBounds = true
yourView.layer.borderWidth = 1.5
yourView.layer.borderColor = UIColor.white.cgColor
yourView.layer.cornerRadius = imageView.bounds.width / 2

How to add shadow to UIView that has round corners

I do believe the issue is with clipping the bounds. If you want to have the view clip the bounds, you should have two views - one for the shadow and one for the content.

Does this work for you?

// corner radius
featureOneView.layer.cornerRadius = 10

// shadow
featureOneView.layer.shadowColor = UIColor.black.cgColor
featureOneView.layer.shadowOffset = CGSize(width: 3, height: 3)
featureOneView.layer.shadowOpacity = 0.6
featureOneView.layer.shadowRadius = 3.0

Make a UIImageView round, add a border, and a shadow around the border

The problem is that shadow is masked together with other content when you set cornerRadius.

You can use an intermediate conteiner view with shadow and masked imageView inside. Here is the code, but you can do the same with Interface Builder and autolayouts as well:

UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(50, 50, 200, 200)];
[containerView.layer setShadowColor:[[UIColor blackColor] CGColor]];
[containerView.layer setShadowRadius:4.0f];
[containerView.layer setShadowOffset:CGSizeMake(0, -3)];
[containerView.layer setShadowOpacity:0.5f];
[self.view addSubview:containerView];

UIImageView *imageView = [[UIImageView alloc] initWithFrame:containerView.bounds];
imageView.image = [UIImage imageNamed:@"rgb"];
[imageView.layer setCornerRadius:imageView.frame.size.width/2];
[imageView.layer setBorderWidth:1];
[imageView.layer setBorderColor:[[UIColor colorWithRed:78.0/255.0 green:82.0/255.0 blue:85.0/255.0 alpha:1] CGColor] ];
[imageView.layer setMasksToBounds:YES];
[containerView addSubview:imageView];

Output:

How can I add shadow to a circle UIImageView or UIView?

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,
