Swift Collcetionview didSelectItemAtIndexPath not working - ios

Question

In myscenario, I am using UICollectionView in Storyboard. The didSelectItemAtIndexPath not working. I have added Imageview on UICollectionView and using customcell.
CollectionView CustomCell
class CustomCollectionViewCell: UICollectionViewCell {
#IBOutlet weak var imageView: UIImageView!
override func draw(_ rect: CGRect) {
super.draw(rect)
self.layer.cornerRadius = self.frame.size.width / 2
}
}
My CollectionView Delegates
class ModernViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
#IBOutlet weak var collectionView: UICollectionView!
override func viewDidLoad() {
super.viewDidLoad()
collectionView.delegate = self
collectionView.dataSource = self
collectionView.allowsSelection = true
}
// MARK: CollectionView Delegate
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return self.listData
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath as IndexPath) as! CustomCollectionViewCell
let item = self.listData[indexPath.item]
let url = item.profileimage
cell.imageView?.sd_setImage(with: URL(string: url ?? "sample.png"), placeholderImage: UIImage(named: "sample.png"))
return cell
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: 35.0, height: 35.0)
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
print("You selected cell #\(indexPath.item)!")
//let item = self.listData[indexPath.item]
//print("SELECTED COLLECTION CELL: \(item.firstname ?? "")")
}
}

Answer 1

remove this line from collectionViewCell class
self.layer.cornerRadius = self.frame.size.width
updated code
class CustomCollectionViewCell: UICollectionViewCell {
#IBOutlet weak var imageView: UIImageView!
override func draw(_ rect: CGRect) {
super.draw(rect)
// self.layer.cornerRadius = self.frame.size.width / 2 // remove this line
}
}
I think you need to set cornerRadius of imageView instead of cell.
self.imageView.layer.cornerRadius = self.frame.size.width/ 2
