一、gesture与tableView手势冲突，didSelectRowAtIndexPath：执行出问题

1、ViewController作为rootViewController，中使用了手势，导致其他页面中tableView,didSelectRowAtlndexpath点击无响应

2、解决方法：

(1)、设置手势的代理为self, 并在ViewController加入UIGestureRecognizerDelegate

(2)、调用 func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool方法

代码如下：

class ViewController: UIViewController,UIGestureRecognizerDelegate {

    override func viewDidLoad() {

        super.viewDidLoad()

        //单击收起菜单手势

        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(handleTapGesture))

        tapGestureRecognizer.delegate = self

        self.view.addGestureRecognizer(tapGestureRecognizer)

    }

    //单击手势响应

    @objc func handleTapGesture() {

        //如果菜单是展开的点击主页部分则会收起

        if currentState == .Expanded {

            animateMainView(false)

        }

    }

    func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {

        print(NSStringFromClass((touch.view?.classForCoder)!))

        if NSStringFromClass((touch.view?.classForCoder)!) == "UITableViewCellContentView"{

            return false

        }

        return true

    }
