在UIView中创建了一个UITableView ，但是tableView的点击事件 和 UITapGestureRecognizer 的冲突。
本篇文章是在 此文章上做的修改。

解决方法：
public func showView(){
UIApplication.shared.keyWindow?.addSubview(self)
self.backgroundColor = UIColor.red
let tapG = UITapGestureRecognizer(target: self, action: #selector(dismissView))
tapG.delegate = self
self.addGestureRecognizer(tapG)
}
extension LeftView :UIGestureRecognizerDelegate{
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
let touchClass = NSStringFromClass((touch.view?.classForCoder)!)
let supClass = NSStringFromClass((touch.view?.superview?.classForCoder)!)
if touchClass == "UITableView" || touchClass == "UICollectionView" ||
supClass == "UITableView" || supClass == "UICollectionView" ||
touchClass == "UITableViewCellContentView" || supClass == "UITableViewCell"
{
return false
}
return true
}
}
