问题描述
如题：我的跟控制器是是个导航控制器，现在有一个A控制器是我push过来的，我希望这个控制器只能点击导航条左边的返回按钮来pop，而侧边右滑动的手势pop我希望能把它禁用掉。当然其他控制器我希望不还是有这个pop的手势。请问我改如何实现呢？
问题解答
回答1：在 A 控制器里写：
- (void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; self.navigationController.interactivePopGestureRecognizer.delegate = self;}- (void)viewWillDisappear:(BOOL)animated{ [super viewWillDisappear:animated]; self.navigationController.interactivePopGestureRecognizer.delegate = nil;}// 给该控制器添加协议 <UIGestureRecognizerDelegate>- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{ return gestureRecognizer != self.navigationController.interactivePopGestureRecognizer;}回答2：
建设从 A -> B 优雅一点的话
在 B 的 viewDidLoad 里面
self.navigationController.interactivePopGestureRecognizer.delegate = self;
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated { [super pushViewController:viewController animated:animated]; self.interactivePopGestureRecognizer.enabled = NO;}
然后在 viewDidDisappear 里面
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
都写在 B 里面，是不是优雅了许多
