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];
}
