uitabbarcontroller

问题 Can someone point me in the right direction with how to set up a UINavigationController inside of a UITabBarController? I have a feeling I'm using initWithRootViewController wrong. ViewController1 *viewController1 = [[[ViewController1 alloc] initWithNibName:@"ViewController1" bundle:nil] autorelease]; self.navController = [[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease]; ViewController2 *viewController2 = [[[ViewController2 alloc] initWithNibName:@

问题 I have an iPhone application that I use the ABPersonViewController and I allow delete. The thing is that the application is a TabBar application and when i use the regular delete method I get this warning: Presenting action sheet clipped by its superview. Some controls might not respond to touches. On iPhone try -[UIActionSheet showFromTabBar:] or -[UIActionSheet showFromToolbar:] instead of -[UIActionSheet showInView:]. the problem is that when I try to press on the "Cancel" of the delete,

问题 I have UITabBarController having 5 tabbar buttons. On some activity I want to unhighlight all the tab bat items. Can anyone help please? Thank you, Ankita 回答1: First of all, I'd like to say that unselecting all tabbaritems is a bad user experience. Chances are high that it won't be accepted into the appstore. After I said that, I found the answere here. You can accept this answer (if it works!!!) but props should be given to that user. He used a trick in Key Value Observing, and used the

问题 I have attached the sample code that illustrates the issue I'm having. For some reason a tableview needs to be the first tab in order for the tableviewcontroller recognize the navbar.

问题 I am developing an App with content that is crosslinked to other content. The App contains 5 Tabs. Each Tab has it's Tableviews and detailsviews. From the detailview of a Tab, one can proceed to other items from another tab. For Example: Tab 1 > TableView List Categories > TableView List Items > DetailView > TableView crosslinked Items > Tab 2 > DetailView (Hope that makes any sense! :D) When I activate the Tab 2 by tabbarController.selectedIndex = 1; it doesn't open the requested detailview

问题 In a tab bar application, I'm adding a view to my first tabbar view by doing: [self.view addSubview:anotherView.view]; Once anotherView is done, I do: [self.view removeFromSuperview]; Which goes back to the parent but doesn't fire viewDidAppear or viewWillAppear on the parent. I can use messaging but it seems there must be a better way. Any suggestions? 回答1: When you add a subview to the first view, it's still visible, just behind the second view. Those methods don't fire because technically

问题 In our current project we had a tab bar controller, and every corresponding view had a tab bar controller. Lately we decided to use another navigation approach and we removed the tab bar controller. Unfortunately the tab bar items in the views seem to be unremovable in the SB. In the running app they are not visible. We even tried to reconnect them to a tab bar controller, but no avail. Also, they don't show up in the document outline. Is there anyone who can spread some wisdom how to remove

问题 I am on the beginning stages of my project. It is a UITabbedApplication with three tabs. The tab at [0] position is the "Location picker", the [1] tab is the "view profiles" from the location picked in the Location picker view. Depending on the location that is first chosen I want the view profiles tab to show profiles from that specific location. Would I be able to do this with container views or is the way I want this set up not going to work? Any advice would be helpful. //tab [0] choose
