title: Presenting a Modal View Controller hides the Navigation Bar
body: <p>I have a navigation based app with a navigation bar, but there are a few instances where instead of pushing a view controller onto the stack, I need to present the view controller modally. The problem is that when I dismiss the modal view controller, everything functions as expected except that the navigation bar is hidden and the (parent view) has been resized, which is the expected behavior according to the docs. So I figured I could simply call a built-in method to unhide the navigation bar. I have already tried</p>
  
  <pre><code>[self.navigationController setNavigationBarHidden:NO];
  </code></pre>
  
  <p>as well as the animated version without success.</p>
  
  <p>The documentation talks about this in the method</p>
  
  <pre><code>presentModalViewController: animated:
  </code></pre>
  
  <p>in the discussion section where it says,</p>
  
  <blockquote>
    <p>On iPhone and iPod touch devices, the view of modalViewController is always presented full screen" and "Sets the modalViewController property to the specified view controller. Resizes its view and attaches it to the view hierarchy."However, the docs didn't clue me in as to how to undo this process after dismissing a modal view.</p>
  </blockquote>
  
  <p>Has anyone else experienced this and found a solution?</p>
  
  <p><strong>Edit: I am having this same problem, so instead of asking my own question I am sponsoring a bounty on this one.  This is my specific situation:</strong></p>
  
  <p>In my case, I am presenting an Image Picker in a Modal View Controller, over a Navigation Controller:</p>
  
  <pre><code>-(void) chooseImage {
      if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
          imagepicker = [[UIImagePickerController alloc] init];
          imagepicker.allowsEditing = NO;
          imagepicker.delegate = self;
          imagepicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
          imagepicker.navigationBar.opaque = true;
          imagepicker.wantsFullScreenLayout = NO;
  
          if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
  
              if (self.view.window != nil) {
                  popoverController = [[UIPopoverController alloc] initWithContentViewController:imagepicker];
  
                  [popoverController presentPopoverFromBarButtonItem:reset permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
              } else {}
  
          } else {
              [self.navigationController presentModalViewController:imagepicker animated:YES];   
          }
      }
  }
  
  -(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
      if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
          [self.popoverController dismissPopoverAnimated:true];
      } else {
          [self.navigationController dismissModalViewControllerAnimated:YES];
      }
      //Save the image
  }
  
  -(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker {
      if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
          [self.popoverController dismissPopoverAnimated:true];
      } else {
          [self.navigationController dismissModalViewControllerAnimated:YES];
      }
  }
  </code></pre>
