swift - 指定VC隐藏导航栏 - 禁用tabbar的根控制器手势，防止两个tabbar跳转 手势冲突

1. viewdidload 设置代理

?

1	self.navigationController?.delegate = self

　　

2.代理里面指定VC 隐藏

?

1 2 3 4 5 6 7 8 9 10 11 12 13

//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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

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

?

1 2 3 4 5 6 7 8

override func viewWillAppear(_ animated: Bool) {     super.viewWillAppear(animated)     self.forbidhenSideBack() } override func viewWillDisappear(_ animated: Bool) {     super.viewWillDisappear(animated)     self.resetSideBack() }
