    SDTabFavorites *sdTabFavViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"tabVC"];
            [self.navigationController pushViewController:sdTabFavViewController animated:YES];
   }

Did select method of SDTabFavorites ViewController

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

Answer 1

Never push VC from login/register to home screen. Always show it in model seque. You need to replace

[self.navigationController pushViewController:sdTabFavViewController animated:YES];

to

[self.navigationController presentViewController:sdTabFavViewController animated:YES completion:NULL];

The Home screen should not have any back button to go back to login/register page.

Thanks, it help me in Xamarin.iOS, I changed :

HomePageViewController homePage = 
this.Storyboard.InstantiateViewController("HomePageViewController") as 
HomePageViewController;
NavigationController.ShowViewController(homePage, this);

to

HomeTabController homePage = 
this.Storyboard.InstantiateViewController("HomeTabController") as 
HomeTabController;
await NavigationController.PresentViewControllerAsync(homePage, true);
