自定义nav返回按钮后，自带的右滑返回功能失效解决方法

百度了一下，用自定义的navigationController，加上以下的方法，可以解决，红色的是主要代码，不知道大牛们有其它的方法bu。

在MainNavigationViewController写：

@interface MainNavigationViewController () <UINavigationControllerDelegate, UIGestureRecognizerDelegate>

- (void)viewDidLoad

{

    [super viewDidLoad];

    self.interactivePopGestureRecognizer.delegate = self;

    self.delegate = self;

}

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

{

    if (self.viewControllers.count > 0) { // 这时push进来的控制器，不是第一个子控制器（不是根控制器）

        // 设置导航栏上面的内容

        // 设置左边返回按钮

        viewController.navigationItem.leftBarButtonItem = [UIBarButtonItem itemWithTarget:self action:@selector(back) image:@"arrow_left_w" highImage:@"arrow_left_w"];

    }

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

        self.interactivePopGestureRecognizer.enabled = NO;

    }

    [super pushViewController:viewController animated:animated];

}

#pragma mark - UIGestureRecognizerDelegate 在根视图时不响应interactivePopGestureRecognizer手势

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer

{

    if (self.navigationController.viewControllers.count == 1) {

        return NO;

    } else {

        return YES;

    }

}

#pragma mark - navigationDelegate 实现此代理方法也是为防止滑动返回时界面卡死

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated

{

    //开启滑动手势

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

        navigationController.interactivePopGestureRecognizer.enabled = YES;

    }

}
