[英]collectionView didSelectItemAt indexPath not called swift
[英]CollectionView didSelectItemAt is not getting called

我有一個 collectionView 並想通過單擊一個項目來執行 segue。 問題是,當我點擊一個項目時,didSelectItemAt 沒有被調用。 我嘗試了不同的模擬器和真實設備。 雖然長按contextMenuConfigurationForItemAt
工作正常。
class RecordsCollectionViewController: UICollectionViewController {
override func collectionView(_ collectionView: UICollectionView, contextMenuConfigurationForItemAt indexPath: IndexPath, point: CGPoint) -> UIContextMenuConfiguration? {
let configuration = UIContextMenuConfiguration(identifier: nil, previewProvider: nil){ action in
let delete = UIAction(title: "Delete", image: UIImage(systemName: "trash.fill"), identifier: nil,discoverabilityTitle: nil, attributes: .destructive, handler: {action in
self.deleteItem(index: indexPath.item)
})
return UIMenu(title: "", image: nil, identifier: nil, children: [delete])
}
return configuration
}
// MARK: UICollectionViewDataSource
override func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return distancesArray.count
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as? RecordsCollectionViewCell {
cell.setupCell(distance: distancesArray[indexPath.item])
return cell
}
return UICollectionViewCell()
}
override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
print("not getting called")
performSegue(withIdentifier: showRecordsTVCsegue, sender: self)
}
}
單元格看起來像這樣:
class RecordsCollectionViewCell: UICollectionViewCell {
@IBOutlet weak var distanceTextView: UILabel!
let formatter = NumberFormatter()
func setupCell(distance: Int32) {
let formatter = NumberFormatter()
formatter.minimumFractionDigits = 0
formatter.maximumFractionDigits = 2
if distance >= 1000 {
self.distanceTextView.text = "\(formatter.string(from: NSNumber(value: Double(distance) / 1000)) ?? "") km"
} else {
self.distanceTextView.text = "\(distance) m"
}
self.layer.cornerRadius = 25
self.clipsToBounds = true
}
}
我在 SO 上嘗試了不同的解決方案,但沒有一個對我有幫助。 例如
collectionView.allowsSelection = true
collectionView.isUserInteractionEnabled = true
而且我也不使用手勢識別器。
