CollectionView didSelectItemAt没有被调用

问题描述

我有一个collectionView,想通过单击一个项目来执行segue。 问题是,当我单击某个项目时,didSelectItemAt没有得到调用。我尝试了不同的模拟器和真实的设备。 尽管长按contextMenuConfigurationForItemAt可以正常工作。

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,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)
  }
}

该单元格如下所示:

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上尝试了不同的解决方案,但没有一个我有帮助。 例如

        collectionView.allowsSelection = true
        collectionView.isUserInteractionEnabled = true

而且我也不使用手势识别器。

解决方法

检查了您的仓库并找到了解决方案。

转到xib中的recordsCell-> ContentView并删除自定义类 RecordsCollectionViewCell ,如屏幕截图所示。
