I have a view inside the table view cell and I want to show shadow to that view if below situations
if view on first cell then drop shadow to top, left, right.
if view on last cell then drop shadow to bottm, left, right.
other wise drop shadow only on left and right.
Thank You.
yourView.layer.shadowColor = UIColor.black.cgColor
yourView.layer.shadowOffset = CGSize(width: 0.0, height: 0.0)
yourView.layer.shadowOpacity = 0.5
yourView.layer.shadowRadius = 2.0
And adapt the code below to the way you want for the corners that you'd like to drop shadow.
var shadowRect: CGRect = yourView.bounds.insetBy(dx: 0, dy: 4) // inset top and bottom of the cell
yourView.layer.shadowPath = UIBezierPath(rect: shadowRect).cgPath
put this code in your class
extension UIView {
func dropShadow(scale: Bool = true) {
layer.masksToBounds = false
layer.shadowColor = UIColor.black.cgColor
layer.shadowOpacity = 0.2
layer.shadowOffset = CGSize.zero
layer.shadowRadius = 5
}}
Then call it:--
YourView.dropShadow(scale: true)

Hi I have normal TableView and I want to update it to be with spaces/gaps between each cell in TableView also from each side(up, down, left, right )
As you can see here:
First of all, you need to create a new UITableViewCell that has one view inside it contentView. You need to make this view that you added smaller than your view and filled so you can create gapes between each tableviewCell.
Like that:
Than you create constraints that will make the view smaller and fit inside the cell like that:
After that you can use this extension here to create the shadow in the view:
https://stackoverflow.com/a/40720122/8792385
The code snippet is something like this:
extension UIView {
// OUTPUT 1
func dropShadow(scale: Bool = true) {
layer.masksToBounds = false
layer.shadowColor = UIColor.black.cgColor
layer.shadowOpacity = 0.5
layer.shadowOffset = CGSize(width: -1, height: 1)
layer.shadowRadius = 1
layer.shadowPath = UIBezierPath(rect: bounds).cgPath
layer.shouldRasterize = true
layer.rasterizationScale = scale ? UIScreen.main.scale : 1
}
}
then you just need to create a reference for your view and in your configuration cell method you call
view.dropShadow()
the result will look something like this:
Following is my code to create CardView and add shadow effect
override func awakeFromNib() {
super.awakeFromNib()
self.layoutIfNeeded()
cellBgview.layer.cornerRadius = 15.0
cellBgview.layer.borderWidth = 1.0
cellBgview.layer.borderColor = UIColor.clear.cgColor
cellBgview.layer.shadowColor = UIColor.gray.cgColor
cellBgview.layer.shadowRadius = 14.0
cellBgview.layer.shadowOpacity = 0.5
cellBgview.layer.shadowPath = UIBezierPath(roundedRect: cellBgview.bounds, cornerRadius: cellBgview.layer.cornerRadius).cgPath
// In
}
This looks like this
Corner radius not working in this case to make corner radius work I have added following code
cellBgview.clipsToBounds = true
After adding above code it looks this
Note that after adding cellBgview.clipsToBounds = true card elevation and shadow is missing but corner radius appears
How to make card view with corner radius and shadow without image getting clip.
Also tried
cellBgview.layer.masksToBounds = true
but it is not working.
Add another UIView in your cell and add imageView in that UIView...Apply corner radius to imageView. Apply shadow to that UIView holding imageView. add clipsToBounds to imageView not to that UIView because clipsToBounds clip anything outside bounds that can be shadow as well. will solve your issue
add a uiview in your cell, lets call it content view. in this view add another uiview in which you'll add the image view and your bottom labels. So actual hierarchy would look like this
--Cell
---UIView //add shadow on this view, also make its backgroundColor to clear color
---UIView //add corner radius to this view and clipsToBounds = true for this view
---UIImageView
---Bottom Labels / Another UIView / Stack View
this hierarchy will help you to achieve the image round corner only on top and view round corners on bottom content
Try this to achieve Shadow, Corner Radius, Border in one view.
cellBgview.backgroundColor = UIColor.white
let cellBgViewLayer = cellBgview.layer()
cellBgViewLayer?.masksToBounds = false
cellBgViewLayer?.shadowColor = UIColor.lightGray.cgColor
cellBgViewLayer?.shadowOpacity = 1.0
cellBgViewLayer?.shadowRadius = 6.0
cellBgViewLayer?.shadowOffset = CGSize(width: 0, height: 0)
cellBgViewLayer?.shouldRasterize = true
cellBgViewLayer?.cornerRadius = 5.0
cellBgViewLayer?.borderColor = UIColor.lightGray.cgColor
cellBgViewLayer?.borderWidth = 1.0
cellBgViewLayer?.shadowPath = UIBezierPath(rect: cellBgview.bounds).cgPath
I have collection view (If the process is easier on a table view I can change it to that).
I need to display the index path of the Cell just before displaying the collection view cell.
I have been trying to figure out how to work on this, here are the things I worked out (Nothing has been a good solution).
Firstly, I tried using a Collection view cell with an added Label (For numbering) and UIView (For showing the content next to it). But the shadow code is not working for the UIView on the collection view cell.
#objc extension CALayer {
func applySketchShadow(
color: UIColor = .black,
alpha: Float = 0.5,
x: CGFloat = 0,
y: CGFloat = 2,
blur: CGFloat = 4,
spread: CGFloat = 0)
{
shadowColor = color.cgColor
shadowOpacity = alpha
shadowOffset = CGSize(width: x, height: y)
shadowRadius = blur / 2.0
if spread == 0 {
shadowPath = nil
} else {
let dx = -spread
let rect = bounds.insetBy(dx: dx, dy: dx)
shadowPath = UIBezierPath(rect: rect).cgPath
}
}
}
#objc extension UIView{
func applyShadowToView(){
self.layer.borderWidth = 1.0
self.layer.borderColor = UIColor.clear.cgColor
self.layer.masksToBounds = true
self.layer.masksToBounds = false
self.layer.applySketchShadow(color: UIColor.black, alpha: 0.09, x: 3, y: 2, blur: 50, spread: 4)
}}
For some weird reasons, my shadow view is not showing up. I tried various codes from online just to be sure, nothing works out.
Other things I thought off are having a header view to show the number of the Collection view, but header view needs to be as wide as Frame so this is not an option and
the other thing is having 2 collection view cells, even cells showing the Number and odd cells showing content.
But the problem with this is I want to add rearranging functionality later on and this method will not work when I want to do it.
I am trying to have the shadow surround a View, but for some reason, the shadow only appears on the top and left side of the View, below is my code and view image. Can someone tell me what I did wrong and how should I change my code, so that the shadow will also appear on the right and bottom? Thank you.
override func awakeFromNib() {
layer.shadowOpacity = 1
layer.shadowRadius = 10
layer.shadowOffset = CGSize(width:1, height: 1)
layer.shadowColor = UIColor.black.cgColor
layer.shadowPath = CGPath(rect: bounds, transform: nil)
}
the view
Is there a way to drop a shadow around the border of a UITextView to give it a 3D effect? The textView has rounded corners.
I don't want to drop a shadow for the content of the textView (i.e. text). Just around the textView border only.
I need to clipToBounds on the textView for the rounded corners.
So far this is what I have tried:
let shadowLayer = CAShapeLayer()
shadowLayer.path = UIBezierPath(roundedRect: textView.bounds, cornerRadius: 15).cgPath
shadowLayer.fillColor = UIColor.clear.cgColor
shadowLayer.shadowColor = UIColor.black.cgColor
shadowLayer.shadowPath = shadowLayer.path
shadowLayer.shadowOffset = CGSize(width: 2, height: 2)
shadowLayer.shadowOpacity = 1
shadowLayer.shadowRadius = 2
textView.layer.addSublayer(shadowLayer)
This results in:
Reason : Clips to bounds = true and shadow on the same view doest not work simultaneous. So to sort out this you have to do follow.
Add your TextView in a UIView (says viewTextBG).
TextView Constraints : top bottom, leading, trailing = 0 wrt. viewTextBG.
Give corner radius to textview and viewTextBG
textview.cornerRadius = 10
viewTextBG.cornerRadius = 10
Give clipsToBounds to textview and viewTextBG
textview.clipsToBounds = True
viewTextBG.clipsToBounds = false
Now give shadow to viewTextBG.
Now everything works, thats all.
