UINavigationController & SplitViewController

Question

I have a project where I use a NavigationController as a detailed view for my SplitViewController.

So when the app shows up, everything is fine in both orientations. However as soon as i push a view inside my navigation controller, if i'm in portrait mode my button to 'show master view' (uisplitview delegate) will disapear and the 'back' button of the uinavigationcontroller will replace it. If i press the back button to pop my view, the 'show master view' button comes back.

My question is, how do i manage the fact that i want to be able to show both buttons ('back', 'show master') in my UINavigationBar even if i have pushed some views?

Answer 1

You simply can't do that with a regular UINavigationBar.

You'd have to place your "show master view" button somewhere else - e.g. in a UIToolbar at the bottom of your detail view.

Or you could code your own NavigationController and NavigationBar, but that's a bit more work. :)

Answer 2

You can do it with a UIToolbar. You must first hide the navigationbar and place a UiToolbar on the top of the view.

Now you can add as buttons as you want.

UIToolbar *tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 20, 1036, 42)];          
tools.barStyle = UIBarStyleBlackTranslucent;
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];

UIBarButtonItem * backButton = [[UIBarButtonItem alloc] initWithCustomView:myCustomView];
[buttons addObject:backButton];

//you can add also a spacer
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[buttons addObject:spacer];

UIBarButtonItem * homeButton = [[UIBarButtonItem alloc] initWithCustomView:myCustomView];
[buttons addObject:homeButton];
[tools setItems:buttons animated:NO];
