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

闲时多研究研究代码或者多多封装一些常用的类，对自己有利而无害，作为一个程序员，我觉得只要多看，多敲，多琢磨，慢慢滴你也就会成为大牛。

 

效果图

 

 

实现步骤：

 

1、viewDidLoad需要做的事情

 

    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

 

-(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

 

 

 

- (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

 

 

 

 

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{

    if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {

        self.interactivePopGestureRecognizer.enabled = NO;

    }

    [super pushViewController:viewController animated:animated];

}
