uitabbar

问题 How does one do this? Note that I do not want a controller. Just a tab bar. 回答1: UITabBar *aTabBar = [[UITabBar alloc] initWithFrame:aFrame]; You’ll probably need to refer to the class documentation for instance methods like -setItems:animated: . Also, see the UITabBarDelegate protocol. 来源： https://stackoverflow.com/questions/3221133/iphone-create-uitabbar-programmatically

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 want to use a UITabBar in my project. I did not create a project that is uitabbar based. I was wondering how for only one page I would be able to use a UITabBar.

I would also like to not restart this project since I have a navigation based project template being used and would like to just add the UITabBar to a single page to go back and forth with two views. The flow of my

Inside one of view controller's thats displayed via tab bar selection, there's a UIButton which needs to display a view modally. I tried [self presentModalViewController:modalNavController animated:YES]; , but the new navigation bar was hidden underneath

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 Since I am developing an iOS >= 5.0 application, I am trying to change the appearance of the main UI components through the appearance proxies. When dealing with the UITabBar component, I correctly changed its tintColor to a light shade of gray trough the [[UITabBar appearance] setTintColor:] method. But doing this, the UITabBarItem s included in the bar are quite impossible to see, since they retain the old gray/white color in their title label. I tried to change their appearance through the
