UIToolbar doesn't get smaller in landscape

Question

In my main view, I add a normal UIToolbar to the bottom of the frame, in landscape it doesn't get smaller? Is this because i dont supply landscape images or am i missing something else? All of the other toolbars in the UINavigationController's all change size in landscape.

Heres how i add this one to the screen.

toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, SCREEN_HEIGHT-64, SCREEN_WIDTH, 44)];
toolbar.translatesAutoresizingMaskIntoConstraints = YES;
[self.view addSubview:toolbar];
[self setupToolbarItems];

setupToolbarItems just creates some of the images for the bar buttons and sets them.

A UIToolbar that you add yourself will not magically change height. If you want it to do so, you must change the height yourself in response to a change in app orientation.

The behavior that you have observed, where a bar changes height, is a feature of UINavigationController; it changes the height of its navigation bar and its toolbar in response to orientation change (as explained in my book: http://www.apeth.com/iOSBook/ch25.html#SBbarMetrics). But this UIToolbar does not belong to a UINavigationController so nothing happens to its height automatically. It's up to you.

This is because you are creating the toolBar's frame but not setting it again when the view is rotated. You need to check when the screen is rotated using [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(resize) name:UIDeviceOrientationDidChangeNotification object:nil];

and then in your -(void)resize; method, you need to resize the toolbar to the new window's size.
