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.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.
- 我怎样才能做到这一点?
- 就所有这些控制器而言，就我的 MainWindow.xib 而言，IB 中的层次结构应该是什么样的?
- 这里的最佳做法是什么?
非常感谢，
推荐答案
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;
