在UITableViewCell中滑動手勢UIImageView

Question

我似乎無法讓我的滑動手勢識別器爲表格視圖單元格內的圖像視圖工作。

我已經證實，images.count> 1.

if images.count > 0 { 
       let imageUrlString = images[0] as String 
       let imageUrl = NSURL(string: imageUrlString) 
       imageCell.cellImageView.sd_setImageWithURL(imageUrl, placeholderImage: UIImage(named: "placeholder")) 

       if images.count > 1 { 
        let swipeRightGestureRecognizer = UISwipeGestureRecognizer(target: self, action: #selector(swipeRight)) 
        swipeRightGestureRecognizer.direction = .Right 
        imageCell.cellImageView.addGestureRecognizer(swipeRightGestureRecognizer) 

        let swipeLeftGestureRecognizer = UISwipeGestureRecognizer(target: self, action: #selector(swipeLeft)) 
        swipeLeftGestureRecognizer.direction = .Left 
        imageCell.cellImageView.addGestureRecognizer(swipeLeftGestureRecognizer) 
       } 
      } else { 
       imageCell.cellImageView.image = UIImage(named: "placeholder") 
      } 

swipeLeft和swipeRight

func swipeLeft(sender: UISwipeGestureRecognizer) { 
     imageView = sender.view as! UIImageView 

     transition.subtype = kCATransitionFromRight 
     imageView.layer.addAnimation(transition, forKey: nil) 

     if imageIndex == images.count - 1 { 
      let urlString = images[0] as String 
      let url = NSURL(string: urlString) 
      imageView.sd_setImageWithURL(url, placeholderImage: UIImage(named: "placeholder")) 

      imageIndex = 0 

     } else { 
      let urlString = images[imageIndex + 1] as String 
      let url = NSURL(string: urlString) 
      imageView.sd_setImageWithURL(url, placeholderImage: UIImage(named: "placeholder")) 

      imageIndex += 1 
     } 
    } 

    func swipeRight(sender: UISwipeGestureRecognizer) { 
     imageView = sender.view as! UIImageView 

     transition.subtype = kCATransitionFromLeft 
     imageView.layer.addAnimation(transition, forKey: nil) 

     if imageIndex == 0 { 
      let urlString = images.last! as String 
      let url = NSURL(string: urlString) 
      imageView.sd_setImageWithURL(url, placeholderImage: UIImage(named: "placeholder")) 

      imageIndex = images.count - 1 

     } else { 
      let urlString = images[imageIndex - 1] as String 
      let url = NSURL(string: urlString) 
      imageView.sd_setImageWithURL(url, placeholderImage: UIImage(named: "placeholder")) 

      imageIndex -= 1 
     } 
    }

// ImageView的defaultly userinteractionenable屬性設置爲false，所以u需要將其設置爲userinteractionenable = true

imageCell.cellImageView.userInteractionEnabled =true
