Why does a cell require a double click in a UICollectionView?
Hello. I have 2 UICollectionView on different controllers which I fill with photos. The code for these collection views is identical (everything is the same in storyboards too), but for some reason, on one controller, the collection view handles clicking on the cell, and on the other controller, you have to make a long or double click on the cell to process the click. Tried debugging, didn't find anything. Also collection views do not overlap other views. What could be the problem?
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return images.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "searchingCell", for: indexPath) as! SearchingCollectionViewCell
cell.configure(stringUrl: images[indexPath.row].fullUrl)
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
collectionView.deselectItem(at: indexPath, animated: true)
let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
guard let viewController = storyboard.instantiateViewController(withIdentifier: "DetailImageViewController") as? DetailImageViewController else { return }
viewController.modalPresentationStyle = .fullScreen
viewController.wallpaperImage = self?.images[indexPath.row]
self?.present(viewController, animated: true, completion: nil)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let frameCollectionView = collectionView.frame
let cellWidth = frameCollectionView.width / CGFloat(countCells)
let cellHeight = CGFloat(250)
return CGSize(width: cellWidth - offsetCells, height: cellHeight - offsetCells)
}
