我正在使用 iOS 上的位置服务开发 IPS。我使用故事板来设计我的视图控制器。当我单击导航视图控制器（使用 iphonelocation 服务显示您的当前位置）时出现问题。无论我想从导航视图控制器转到哪个页面（主视图控制器、约会视图控制器等），整个应用程序都会崩溃。想寻求帮助解决这个问题，尝试3天后完全失败。

//  MenuViewController.m
@implementation MenuViewController

- (void)viewDidLoad
{
  [super viewDidLoad];
  [self.slidingViewController setAnchorRightRevealAmount:280.0f];
  self.slidingViewController.underLeftWidthLayout = ECFullWidth;
}

-(void)goToPage:(NSString*) page
{
    UIViewController *newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:page];
   [self.navigationController pushViewController:newTopViewController animated:YES];
    [self.slidingViewController anchorTopViewOffScreenTo:ECRight animations:nil onComplete:^{
        CGRect frame = self.slidingViewController.topViewController.view.frame;
        self.slidingViewController.topViewController = newTopViewController;
        self.slidingViewController.topViewController.view.frame = frame;
        [self.slidingViewController resetTopView];
    }];
}

- (IBAction)goToMainMenu:(id)sender
{
    [self goToPage:@"MenuMain"];
}

- (IBAction)goToAppointment:(id)sender
{
    [self goToPage:@"Appointment"];
}

- (IBAction)goToFindADoctor:(id)sender
{
    [self goToPage:@"FindADoctor"];
}

- (IBAction)goToNavigation:(id)sender
{
    [self goToPage:@"Navigation"];
}

- (IBAction)goToViewQueue:(id)sender
{
    [self goToPage:@"ViewQueue"];
}

@end
