问题描述
大家好，我是iPhone开发的新手，我不了解整个UINavigationController和UITabBarController的想法。是一个替代另一个 - Tweetie等应用程序如何结合两者？
Hey everyone, I am new to iPhone development and I'm not understanding the whole UINavigationController and UITabBarController idea. Is one a substitute for the other - how do apps such as Tweetie combine both?
我想让我的应用程序在底部有一个持久的Tab Bar（似乎工作正常），但顶部的导航栏可以在不移除标签栏的情况下将视图推送/弹出到屏幕上。
I'd like to have my app have a persistent Tab Bar @ the bottom (which seems to be working), but also a Navigation bar at the top which can push/pop views onto the screen without removing the tab bar.
- 我怎样才能做到这一点？
- 对于所有这些控制器，IB的层次结构在我的MainWindow.xib中应该是什么样的？
- 这里的最佳做法是什么？
非常感谢，
推荐答案
将视图控制器包装在 UINavigationController 中，并将 UINavigationController 放在 UITabBar中。
这对你来说很好......
Just wrap the view controller inside the UINavigationController and Place the UINavigationController inside the UITabBar. This will work fine for you…
示例：
NSMutableArray *tabBarViewControllers = [[NSMutableArray alloc] initWithCapacity:2];
tabBarController = [[UITabBarController alloc] init];
[tabBarController setDelegate:self];
UINavigationController *navigationController = nil;
navigationController = [[UINavigationController alloc] initWithRootViewController:<Your View controller1>];
[tabBarViewControllers addObject:navigationController];
[navigationController release];
navigationController = nil;
navigationController = [[UINavigationController alloc] initWithRootViewController:<Your View controller2>];
[tabBarViewControllers addObject:navigationController];
[navigationController release];
navigationController = nil;
tabBarController = tabBarViewControllers;
[tabBarViewControllers release];
tabBarViewControllers = nil;
