iOS之侧滑返回无需第三方，只需在自己的BaseNavController添加大概20行代码即可

实现步骤：

1、viewDidLoad需要做的事情

1 2 3 4 5 6 7 8

self.delegate = self;           __weak typeof(self) weakSelf = self;           if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {                   self.interactivePopGestureRecognizer.delegate = weakSelf;     }

2、实现UIGestureRecognizerDelegate代理中的方法

1 2 3 4 5 6 7

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

3、实现UINavigationControllerDelegate代理中的方法

• 1.实现didShowViewController方法

1 2 3 4 5 6 7 8 9 10 11

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{           if ([navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {         navigationController.interactivePopGestureRecognizer.enabled = YES;     } //使navigationcontroller中第一个控制器不响应右滑pop手势     if (navigationController.viewControllers.count == 1) {         navigationController.interactivePopGestureRecognizer.enabled = NO;         navigationController.interactivePopGestureRecognizer.delegate = nil;     } }

• 2.此方法中拦截所有push 进来的控制器

1 2 3 4 5 6

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{     if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {         self.interactivePopGestureRecognizer.enabled = NO;     }     [super pushViewController:viewController animated:animated]; }
