My drawer start screen is missing navigation bar

I am making one iOS app where I am using MMDrawer. The problem is the toolbar which is not showing my drawer button. I can't even find the navigation bar on this screen through which I want to show the side drawer menu.

I am initializing the box by following the code in my login screen button

AppDelegate *aPPDel=(AppDelegate*)[[UIApplication sharedApplication] delegate];

UIViewController * leftSideDrawerViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"sidemenuvc"];

UINavigationController * leftSideNavController = [[UINavigationController alloc] initWithRootViewController:leftSideDrawerViewController];

UIViewController * centerSideDrawerViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"homevc"];

UINavigationController * centerSideNavController = [[UINavigationController alloc] initWithRootViewController:centerSideDrawerViewController];
MMDrawerController *drawerController = [[MMDrawerController alloc] initWithCenterViewController:centerSideNavController  leftDrawerViewController:leftSideNavController];
[leftSideDrawerViewController.navigationController setToolbarHidden:NO];
 [centerSideDrawerViewController.navigationController setToolbarHidden:NO];
[drawerController setShowsShadow:NO];

[drawerController setMaximumRightDrawerWidth:200.0];
[drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
[drawerController setCloseDrawerGestureModeMask:MMCloseDrawerGestureModeAll];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:drawerController];
[aPPDel.window setRootViewController:navigationController];

      

        
        
        
      

    

in my home screen toolbar, I wrote this code

[self.mm_drawerController toggleDrawerSide:MMDrawerSideLeft animated:YES completion:nil];

      

        
        
        
      

    

I tried all possible ways to show the navbar (hidden is not) but could not find a solution
