Removing titlebar from 'Utility Application's flipside view

Question

I've put a table on the flipside of my Utility Application template. The template automatically puts a titlebar with a done button to go back to the front view.

When one of the cells in the flipside's table is selected, it brings up the Camera / Image Library picker. But it leaves the titlebar is position, partially obscuring the picker interface.

How do I remove the titlebar while the picker is in effect? thanks

Answer 1

1. Add an outlet to FlipsideViewController.h for the UINavigationBar.
2. Open the FlipsideView.xib and connect the outlet.
3. When showing the image picker, set the hidden property of the UINavigationBar to true.
4. When the image picker is dismissed, set the hidden property to false.

Answer 2

I'm going in completely in circles here. There is obviously something fundamental I am not understanding...

In my RootViewController, to load the FlipsideView:

FlipsideViewController *viewController = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil];
self.flipsideViewController = viewController;

[viewController release];


// Set up the navigation bar
UINavigationBar *aNavigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 44.0)];
aNavigationBar.barStyle = UIBarStyleBlackTranslucent;
self.flipsideNavigationBar = aNavigationBar;
[aNavigationBar release];

UIBarButtonItem *buttonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(toggleView)];
UINavigationItem *navigationItem = [[UINavigationItem alloc] initWithTitle:@"App Title"];
navigationItem.rightBarButtonItem = buttonItem;
[flipsideNavigationBar pushNavigationItem:navigationItem animated:NO];
[navigationItem release];
[buttonItem release];

Meanwhile, in my FlipViewController, this shows the image picker:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

// THIS IS NOT WORKING
[self.navigationController.navigationBar setHidden:YES];

[self presentModalViewController:picker animated:YES];
[picker release];

I've commented the bit that I thought would remove the navigation bar.

Inside the animation block where you perform the UIViewTransitionAnimationFlipFromLeft (Or UIViewTransitionAnimationFlipFromRight), add the removal of the navigation bar:

[flipsideNavigationBar removeFromSuperView];
