uitabbarcontroller

问题 I have an existing iPhone project that has been tested, submitted, and approved, compiled with the 3.1.3 SDK. I've taken this project and converted it to a universal iPad/iPhone app, following Apple's instructions (i.e. letting Xcode do its magic). This app has a UITabBarController as its root view controller, built inside a XIB. When run on the 4.0 iPhone simulator, it works fine. When running on the 3.2 iPad Simulator or the device itself, it has one major flaw: the UITabBar is unresponsive

问题 I'm facing a bug with my UITableView in UIViewController . I'll try to explain what's the situation and my problem. I have a TabBarController which a view is a UIViewController with a UITableView . I don't use a UITableViewController because I have some specifics controls on my UIViewController . So, when my UIViewController isn't a child of my TabBarController , everything is okay : all rows are displayed correctly. But, when I set my UIViewController as a child of my TabBarController , I

问题 I want to change tab through code with animation. Exact scenario is that there are 2 tabs with below hierarchy. First tab - Navigation controller - Login controller - Some other controller Second tab - Navigation controller - Screen with Logout button Now, if user presses logout, I need to display login screen. For that I need to switch tab to FirstTab and then popToRootViewController. So what I am doing is on logout button press I send NSNotification to LoginController which in turn executes

问题 This is more of a philosophical question than anything, so give me your thoughts. The iPhone SDK documentation specifies that you may have a tab bar controller contain a navigation controller, but you can't have a navigation controller contain a tab bar controller. It seems that there are times when you might want to organize views within a view that is part of a navigation controller stack in a tabular fashion. Is this unreasonable?
