关于导航栏右滑返回的工具库 FDFullscreenPopGesture 是 OC 版本,用了 runtime 等各种骚操作

关于 swift ,我在 UINavigationController 的 viewDidLoad 方法中

class GMNavigationController: UINavigationController {

    override func viewDidLoad() {
super.viewDidLoad() self.addPanGes()
}
/// 将导航栏的右滑手势添加到 view 上面
func addPanGes() { interactivePopGestureRecognizer?.delegate = self
guard let targets = interactivePopGestureRecognizer?.value(forKey: "_targets") as?[AnyObject] else {
return
}
let dict = targets[]
//拿到action
let target = dict.value(forKey: "target") as Any
//通过字典无法拿到action,这里通过Selector方法包装action
let action = Selector(("handleNavigationTransition:"))
//拿到target action 创建pan手势并添加到全屏view上
let gesture = UIPanGestureRecognizer(target: target, action: action)
view.addGestureRecognizer(gesture)
     // 这里需要将导航栏的右滑手势去掉
self.interactivePopGestureRecognizer?.isEnabled = false
}
}

这样就可以达到的效果了。
