UICollectionViewCell-XWEdit

类似UITableViewCell滑动删除（Switf） 可高度自定义滑动出现的视图 使用便捷(代码如下)

注：xw_rightEidtView，xw_leftEidtView为cell扩展的属性

    let view: UIView = UIView.init(frame: CGRect.zero)
    view.backgroundColor = UIColor.red
    let btn: UIButton = UIButton.init(frame: CGRect.zero)
    btn.setTitle("删除", for: .normal)
    btn.setTitleColor(UIColor.white, for: .normal)
    view.addSubview(btn)
    btn.snp.makeConstraints({ (make) in
        
        make.center.equalTo(btn.superview!);
        make.left.equalTo(btn.superview!).offset(25);
        make.right.equalTo(btn.superview!).offset(-25);
    })
    
    self.xw_rightEidtView = deleteView
