uitabbarcontroller

问题 I'd like to be able to give my views short names for display on the tab bar, and longer (more descriptive) name when the same view is linked to in a table view. The reason is that longer names nudge up against each other on the tab bar. In a table view, there's more horizontal space, so I want to use more descriptive titles there. Normally, the tab bar's title is set in its view controller with self.title . Is there a way to specifically set the tab bar title, but leave the view controller's

问题 I have been unable to google an acceptable solution to this that can be applied to my project. My app is a graphing tool that has three tabs; one for the graph itself and the other two are for browse/search functions for things that can be added to the graph. All tabs are navigation controllers. The tab for the graph itself, when in portrait mode, displays a small preview of the graph and lists details of each entity that is on the graph below, and displays the tab bar at the bottom. When the

问题 I'm trying to set the icon color and background color of an individual item on my TabBar within the TabBarController.

The specific icon is (the one in the middle of the image) for my camera feed, this icon i would like to be white and the background to be red. My code so far is such - On my

问题 I have created a tab bar with 5 tabs. we want to create a feature that we can enable/disable some tabs of tab bar programmatically so that user will not able to click on it.

问题 I am trying to include a navigation controller within the third tab of my tabbarcontroller. I have had some feedback but am only able to get about this far. The code below doesn't produce any errors, but does not seem to work as the app just quits out. Does anyone have any input on what I might be doing wrong? UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:@"PDCFirstViewController" bundle:nil]; UIViewController *viewController2 = [[SecondViewController alloc]

问题 I have two problems I am trying to solve, one is refreshing the tab controller itself and the other is refreshing the content of the tabcontroller. The reason I wish to refresh the tab controller itself is that my application has a web call which returns a JSON which sets up the order of the tabs and also sets up the content of each tab. I have got it so that when you back out of the application and reenter the application the tab controller is refreshed by putting exit(0) in the AppDelegates
