问题 I have an app with a tabbar and a navbar. I have a BaseVC and a DetailVC . I'm pushing DetailVC from BaseVC . I want the tabbar to be under the pushed VC DetailVC . I'm using hidesBottomBarWhenPushed to achieve it. It works great, but for some reason while it's animating the push the tabbar is still visible and just when the animation ends the tabbar is hidden. I want it to be under the pushed VC in the animation too. My code is: self.hidesBottomBarWhenPushed = true self.navigationController?

问题 In my iPhone app, to restore previously viewed tab, on launch I set the setSelectedIndex: (also tried setSelectedViewController: as per docs but to no avail) This works on iPhone OS 3.0 - however on OS 2.x the selected index greater than 3 (the first 4 tabs) doesn't switch to the required view. This is documented by Apple here: http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UITabBarController_Class/Reference/Reference.html#//apple_ref/occ/instp/UITabBarController

I would really like for the calling object to not have to worry about device or orientation, but instead pass as input the view controllers that are in the tab bar on iPhone in portrait and in the root view

问题 I have a navigation controller with 4 tab bar items. Each one has a navigation controller inside. I want to be able to change the 4th tab bar badge number when I get push notification, no matter in what view or tab am I. I need to use the auto-layout so I can't use any programmatically solution inside the app delegate. I started the project from a single view template.
