1. viewdidload 设置代理
self.navigationController?.delegate = self
2.代理里面指定VC 隐藏
//MARK: - 导航栏delegate extension JYHomeViewController:UINavigationControllerDelegate { /// 此方法会在controller的viewWillApper方法调用后开始调用(使用时注意controller的生命周期) func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) { if viewController is JYHomeViewController || viewController is JYPhotoBrowserController || viewController is JYRTSRootViewController { JY_WINDOW?.removeBubbleView() self.navigationController?.setNavigationBarHidden(true, animated: true) }else{ self.navigationController?.setNavigationBarHidden(false, animated: true) } } }
3. 在根控制器首页 禁用手势, 不管有几个 homeVc, 有俩tabbar 就在俩homeVc都写上
extension JYHomeViewController: UIGestureRecognizerDelegate { /// 禁止使用手势返回 func forbidhenSideBack() { self.isCanSideBack = false if (self.navigationController?.responds(to:#selector(getter: self.navigationController?.interactivePopGestureRecognizer))) == true { self.navigationController?.interactivePopGestureRecognizer?.delegate = self } } /// 恢复手势返回 func resetSideBack() { self.isCanSideBack = true if (self.navigationController?.responds(to:#selector(getter: self.navigationController?.interactivePopGestureRecognizer))) == true { self.navigationController?.interactivePopGestureRecognizer?.delegate = nil } } func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool { return self.isCanSideBack } }
在 willappear 和willDisaapper 使用
override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) self.forbidhenSideBack() } override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) self.resetSideBack() }
