I have a simple problem that I cannot find a solution to on google, the docs or here.
I have a Collectionview in my view controller. I have created a custom cell, DescriptionCell, that contains a UIImage. I want this image to have rounded corners. However, I don't know where to set the cornerradius on the UIImage layer. I have tried in the cells' awakeFromNib method, in the delegate method CellForRowAtIndexPath and overriden LayoutSubview in the cell but it does not work.
Where should I put the code to set the radius for the UIImage?
To specify, I know how to create rounded corners of a UIImage. But if it is a subview of a Collectionview cell, I do not know where to set the cornerradius.
Here is code for my descriptionCell
class DescriptionCell: UICollectionViewCell {
@IBOutlet weak var mImage: UIImageView!
override func awakeFromNib() {
//mImage.layer.cornerradius = 5
//Does not work, the image is still square in the cell
}
And in the cellforRowAtIndePath
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
var cell = collectionView.dequeueReusableCellWithReuseIdentifier("descriptioncell", forIndexPath: indexPath) as! DescriptionCell
//cell.mImage.layer.cornerradius = 5
//Does not work, the image is still square in the cell
return cell
}
Thanks in advance!

Well you're using part of the code from the answer you said you were using. the other part is
imageView.clipsToBounds = true
Update your
awakeFromNib
like this:To make it a circle you need to set cornerRadius to half of the square height. In your
cellForItemAtIndexPath
add these lines:Update
To avoid
layoutSubviews
from being called twice, overridelayoutSubviews
in yourDescriptionCell
class and put the code there:
