单独使用UINavigationViewController

Question

在我的应用程序中，它基于一个tabbar视图控制器，每个tabbar项目有许多uinavigationviewcontrollers，我想在某个时候（在应用程序启动时）调用presentModalViewController，它包含一个uinavigationcontroller作为root，这样用户可以做一些事情......当他或她完成时，可以点击右上角的完成按钮以关闭模态视图控制器，然后返回到基本标签栏视图....如何使用Interface Builder？

Answer 1

In XCode, create a new View XIB file and open it in Interface Builder. In this xib file, delete the View and drag a UINavigationController into it's place.

Then, in your view controller code, something like

UINavigationController *controller = [[UINavigationController alloc] initWithNibName:@"ModalViewController" bundle:nil];
[self presentModalViewController:controller animated:YES];
[controller release];

Will load your XIB and present it.

Hope this helps, any other questions don't hesitate to comment on this answer!
