//添加代理<UIGestureRecognizerDelegate> 实现代理方法  全部都放在  导航根视图里面
@interface SCNavigationController () <UIGestureRecognizerDelegate>

@end

@implementation NavigationController

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

#pragma mark - 返回手势
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    if (self.navigationController.viewControllers.count == 1) {//关闭主界面的右滑返回
        return NO;
    } else {
        return YES;
    }
}
