大家好，我是 iPhone 开发的新手，我不了解整个 UINavigationController 和 UITabBarController 的想法.一个可以替代另一个 - Tweetie 等应用如何将两者结合起来?
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标签栏(这似乎正在工作)，但在顶部还有一个导航栏，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.
非常感谢，
只需将视图控制器包装在 UINavigationController 中，并将 UINavigationController 放入 UITabBar.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…
例子:
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;
