swift cell 自定义左滑手势处理方法

swift cell自定义左滑手势处理，代码如下所示：

public override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
      super.init(style: style, reuseIdentifier: reuseIdentifier)
      initUI()
      makerLayout()
      /// 直接调用手势方法-手势添加在了contentView上
      makerPang()
  }
private func makerPang(){
      let p = UIPanGestureRecognizer(target: self,action: #selector(pangAction(_:)))
      p.delegate = self
      contentView.addGestureRecognizer(p)
  }
  
  @objc func pangAction(_ guest: UIPanGestureRecognizer){
      let state = guest.state
      let x = guest.location(in: self).x
      if state == .began{
          startp = x-conView.mm_x
      }else{
          let gap = x-startp
          if state == .changed{
              if gap<0 {
                  conView.mm_x = max(x-startp, -140)
              }else{
                  conView.mm_x = gap
              }
          }else{
              UIView.animate(withDuration: 0.2) {
                  self.conView.mm_x = gap <= -70 ? -140 : 0
              }
          }
      }
  }
