Sigabrt Error- UIGestureRecognizer programatically

Question

В настоящее время я пытаюсь добавить салфетки вверх и вниз в ячейки моего UICollectionView для выполнения определенных действий. Я сделал это все программно, но я получаю сигабрт. Какие-либо предложения?

class TableViewCell: UITableViewCell, UICollectionViewDataSource, UICollectionViewDelegate { 

    var collectionView: UICollectionView! 
    var cellTextLabel: UILabel! 




    override init(style: UITableViewCellStyle, reuseIdentifier: String?) { 
     super.init(style: style, reuseIdentifier: reuseIdentifier) 


     let layout = UICollectionViewFlowLayout() 
     layout.scrollDirection = UICollectionViewScrollDirection.horizontal 
     layout.itemSize = CGSize(width: 90, height: 90) 
     collectionView = UICollectionView(frame: self.bounds, collectionViewLayout: layout) 

     collectionView.delegate = self 
     collectionView.dataSource = self 
     collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "CollectionViewCell") 

     collectionView.backgroundColor = UIColor(red: 34.0/255.0, green: 40.0/255.0, blue: 51.0/255.0, alpha: 1.0) 
     collectionView.frame.size.height = 120 
     collectionView.frame.size.width = 500 
     self.addSubview(collectionView) 


    } 

    required init(coder aDecoder: NSCoder) { 
     super.init(coder: aDecoder)! 
    } 

    func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int { 
     return 1 
    } 


    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
     return 10 
    } 

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 




     var arrayOfReviewVocab = ["衣服" + "\n" + "clothes", "学校" + "\n" + "school", "你好" + "\n" + "hello", "书" + "\n" + "books", "5", "6", "7", "8", "9", "10"] 

     let cell: UICollectionViewCell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionViewCell", for: indexPath) as! UICollectionViewCell 

     cell.backgroundColor = UIColor(red: 30.0/255.0, green: 35.0/255.0, blue: 46.0/255.0, alpha: 1.0) 

     cellTextLabel = UILabel(frame: CGRect(x: 20 , y: -20, width: frame.size.width, height: frame.size.height)) 
     cell.contentView.addSubview(cellTextLabel!) 
     cellTextLabel.textColor = UIColor.white 
     cellTextLabel.text = arrayOfReviewVocab[indexPath.row] 
     cellTextLabel.numberOfLines = 0 

     var swipeUp = UISwipeGestureRecognizer(target: cell, action: "handleSwipeGesture:") 
     swipeUp.direction = .up 
     cell.addGestureRecognizer(swipeUp) 

     var swipeDown = UISwipeGestureRecognizer(target: cell, action: "handleSwipeGesture:") 
     swipeDown.direction = UISwipeGestureRecognizerDirection.down 
     cell.addGestureRecognizer(swipeDown) 
     return cell 
    } 

    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize { 
     return CGSize(width: 200, height: 200); 
    } 



    func handleSwipeGesture(gesture: UISwipeGestureRecognizer) 
    { 


     if(gesture.direction == .up) 
     { 
      print("up") 
     } 

     if (gesture.direction == .down) 
     { 
      print("down") 
     } 

    } 

} 

Вот сообщение об ошибке:

[UICollectionViewCell handleSwipeGesture:]: unrecognized selector sent to instance 0x7fd2fb61ee20 

Answer 1

Вы должны установить цель: самостоятельно не цель: клетка, если метод handleSwipeGesture: в классе TableViewCell

var swipeDown = UISwipeGestureRecognizer(target: self, action: "handleSwipeGesture:") 

Answer 2

var swipeUp = UISwipeGestureRecognizer(target: self, action: #selector(self. handleSwipeGesture)) 
swipeleft.direction = .Up 
cell!.addGestureRecognizer(swipeUp) 

Same как для Вниз.

Счастливое кодирование.
