问题 I'm new to iphone development. I've read tutorials about implementing a tab bar controller on the window (eg as the main controller for the app). But how can I create a tab bar controller as a 'standalone' UIViewController that can be called by a navigation bar controller? Basically my navigation bar controller has an array of UIViewControllers that it displays in the table and then loads the appropriate view/controller when a user selects an item. Now I want one of these loaded views

问题 When in the Camera Roll section of the Photos app, you can click the top right button to edit the photos. This replaces the bottom tab bar with three new buttons which are in a UIToolBar. I would like to do something similar, but I cannot get my UIToolBar to be on TOP of the tab bar. Is there a way to specify the layer order? Or do I need to do something different? 回答1: You may be able to add the toolbar as a subview of your key window: [[[UIApplication sharedApplication] keyWindow]

问题 I have a working iPhone app with a UITabBarController. It all works fine. The app has more tabs than can be shown across the portrait width of the display, so we see 5 tabs in total (the last being the "more" tab). The thing is, we want to relegate some of the "less interesting" things to be behind the "more" tab. I know that if I had just 2 view controllers, then I'd see just 2 tabs, and so on until I exceeded 5 tabs. How can we show just 4 tabs (3 plus a "more" tab), instead of 5? My guess

问题 I have an app with a tab bar, which contains 5 tabs. I decided to have a "Home screen" instead of opening the app directly in the first tab. My home screen will contain a welcome message AND 5 buttons to segue directly to the wanted tab. Example: the 4th button will go to the 4th tab. After clicking one button, the home screen should never be seen again. The navigation mode will by the tab bar. My Home View Controller 5 buttons and a reference to the Tab Bar Controller, to pass the button
