uinavigationbar

I've created custom transitions between view controllers using the following protocols: UIViewControllerAnimatedTransitioning and UIViewControllerTransitioningDelegate Is it possible using the default UINavigationBar , to create custom transitions for the titles, right now they simply crossfade between view controllers, Or do i have to built my own navigation bar view from scratch? WWDC 2013 video #218 indicates that all custom transitions will crossfade the navigation bar, and that there's no way to customize this behavior. xaphod If your transition is both custom and interactive, then you

In my iPad app I have an application settings view. One of the options lets the user switch interface color scheme. The settings view is loaded by segue to a separate view controller than my "main" app's window. When they pick a new color I switch the colorSchemeColor variable and do this: // set the colors and refresh the view [[UINavigationBar appearance] setBarTintColor:colorSchemeColor]; [[UIToolbar appearance] setBarTintColor:colorSchemeColor]; [[UITabBar appearance] setBarTintColor:colorSchemeColor]; However, none of the bars change color until I exit my settings view!

It seems the only way to remove a navigation bar with animation is via it sliding upward. I want it to fade, like in Photos.app. It would be easiest to change the alpha, however Apple's guidelines state : Prior to iOS v5.0, when used in conjunction with a navigation controller, there are only a handful of direct customizations you can make to the navigation bar.

I am working on an iPhone application which works in both orientations: portrait and landscape. I am using for one view and tableview embedded in an UINavigationController. The height of this navigationbar with its buttons is either: 44px portrait or 34px landscape. Within a different view I created the UINavigationBar by myself and I am able to set the frame for the correct size, but the embedded UINavigationItem with UIBarButtonItem doesn't shrink. So for the 34 px in the landscape mode this button is to big and overlaps the navbar in the height. The funny thing is though, that this worked
