UICollectionView Cell Shadow

Question

I am trying to add shadow to my custom UICollectionViewCell, This is the code I am using in my custom collection view cell class:

self.layer.shadowO         


        

Answer 1

Go to CustomCollectionViewCell.m file Worked for me. Hope it helps...

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        //////// make shadow  of total view
        self.clipsToBounds = NO;
        self.layer.masksToBounds = NO;
        self.layer.shadowRadius = 5;
        self.layer.shadowOpacity = 0.5;
        self.layer.shadowColor = [UIColor blackColor].CGColor;
        self.layer.shadowOffset = CGSizeMake(0, 1);
        self.layer.shadowPath = [UIBezierPath bezierPathWithRect:self.bounds].CGPath;

        // make radius of the cell
        self.layer.cornerRadius = 5;

    }
    return self;
}

Answer 2

Don't forget to add these 2 lines

self.clipsToBounds = false      
self.layer.masksToBounds = false

Answer 3

cell.layer.backgroundColor should not be clear color

try

cell.layer.backgroundColor = UIColor.white.cgColor

Answer 4

Swift 4.2 and xcode 10

here's code for adding a shadow.

    cell.contentView.layer.cornerRadius = 2.0
    cell.contentView.layer.borderWidth = 1.0
    cell.contentView.layer.borderColor = UIColor.clear.cgColor
    cell.contentView.layer.masksToBounds = true

    cell.layer.backgroundColor = UIColor.white.cgColor
    cell.layer.shadowColor = UIColor.gray.cgColor
    cell.layer.shadowOffset = CGSize(width: 0, height: 2.0)//CGSizeMake(0, 2.0);
    cell.layer.shadowRadius = 2.0
    cell.layer.shadowOpacity = 1.0
    cell.layer.masksToBounds = false
    cell.layer.shadowPath = UIBezierPath(roundedRect:cell.bounds, cornerRadius:cell.contentView.layer.cornerRadius).cgPath
