手势返回失效 iOS

自定义返回按钮，设置 setLeftBarButtonItem 后，系统的滑动手势返回会失效。

BaseNavigationController里，加下面的逻辑。

- (void)viewDidLoad {[super viewDidLoad];self.interactivePopGestureRecognizer.delegate = self;
}

 

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{self.interactivePopGestureRecognizer.enabled = YES;
}

 

导航栈顶部VC，首页滑动返回，会出现卡死现象，需要加以下代码解决

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer*)gestureRecognizer {if (self.viewControllers.count == 1){return NO;}return YES;
}
