1、設定自定義的右滑手勢，別忘記禁止系統右滑手勢

let target = self.interactivePopGestureRecognizer?.delegate
        let pan:UIPanGestureRecognizer = UIPanGestureRecognizer.init(target: target!, action: Selector(("handleNavigationTransition:")))
        self.view.addGestureRecognizer(pan)

        self.interactivePopGestureRecognizer
 
?.isEnabled = false
        pan.delegate = self

2、UIGestureRecognizerDelegate代理方法篩選手勢作用條件

設定根控制器右滑手勢不起作用，如果不設定，一旦在根控制器中右滑，將造成app卡死

    func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
        return self.childViewControllers.count > 1
    }

這樣即可
