I have a UITabBarController where the default view controller is a UINavigationController . I want to be able to hide the UITabBar of the UITabBarController when I push a certain view in the UINavigationController . I've tried adding: delegate.tabBarController.hidesBottomBarWhenPushed = YES; in my UINavigationController before I push the view, but that doesn't seem to do the trick. Any tips on what I should be doing or if it's even possible? Thanks in advance! Source: Tips4all

I have implemented a custom tabbar in my app. Where I can scroll on the tab, and also the tab can have more than 5 buttons. The problem is when i pick a video with imagepickercontroller, the compressing video dialog box shows up. The video is compressed and when the imagepicker is dismissed, my custom tabBar gets distorted. The default tabbar shows at the bottom of the screen along with my custom tabbar. And this problem is only when i run the app on iOS 5 device. Please help me out here, either tell me how to avoid compression (tried setting the video quality to 'HIGH'), or some way around the compression thing.

As above, I can't seem to change the background color or image of the tabBar. Even when hiding it by changing alphan 0, I still see it as a black solid bar. How can I fix this?
