自定义UITabBarController选项卡的“更多”列表

I am writing an App based on UITabBarController which has more than 10 viewControllers with corresponding UINavigationControllers. Each viewContoller has a (short) Title and a (long) navigationTitle. The short title shows up under the TabBar icon and the long title shows up on top of the navigation bar.I am writing an App based on UITabBarController
