在 iPhone 中推送 tabbarcontroller / 在 iPhone 应用程序中推送多个 tabbarcontroller

发布于 2024-11-07 16:34:21 字数 93 浏览 0 评论 0原文

我创建了一个基于选项卡栏的项目，我的第一个选项卡有一个导航控制器。在我的导航控制器中（推送 2 个视图后）我想添加/推送另一个选项卡控制器。所以请有人建议我如何做到这一点。

更新：再次阅读您的文章后，我想我误解了它！ UINavigationControllers 内部不能有 UITabBarController，它只能以相反的方式工作！

如果你真的想这样做（真的想一想！！），你可以编写自己的 UITabBarController 实现，它在 UINavigationController 中很满意（Twitter for iPhone 使用这样一个自定义编写的 UITabBarController）

链接： UITabBarController内部UINavigationController

只是将包含 UIView 的 NSArray 提供给 tabbarcontrollers viewControllers 属性。
tabcontroller =[[UITabBarController alloc] init];

UINavigationController *navcon = [[UINavigationController alloc] init];
UINavigationController *navcon2 = [[UINavigationController alloc] init];
UINavigationController *navcon3 = [[UINavigationController alloc] init];
[navcon pushViewController:someuiview animated:NO];
[navcon2 pushViewController:someuiview2 animated:NO];
[navcon3 pushViewController:someuiview3 animated:NO];

[someuiview release];[someuiview2 release];[someuiview3 release];

tabcontroller.viewControllers=[NSArray arrayWithObjects:navcon, navcon2, navcon3, nil];
[navcon release]; [navcon2 release]; [navcon3 release];

someuiviewn 是 UIViewControllers 的子类（例如 UITableViewControllers（或者其他什么:)）

UPDATE: After reading your post once more I think I misunderstood it! UINavigationControllers can't have a UITabBarController inside them, it only works the other way round!

If you really want to do this (really think about it!!) you could write your own implementation of a UITabBarController that is happy inside of a UINavigationController (Twitter for iPhone uses such a custom written UITabBarController)

Link: UITabBarController insider UINavigationController

Just feed the tabbarcontrollers viewControllers property with an NSArray containing your UIViews.
tabcontroller =[[UITabBarController alloc] init];

UINavigationController *navcon = [[UINavigationController alloc] init];
UINavigationController *navcon2 = [[UINavigationController alloc] init];
UINavigationController *navcon3 = [[UINavigationController alloc] init];
[navcon pushViewController:someuiview animated:NO];
[navcon2 pushViewController:someuiview2 animated:NO];
[navcon3 pushViewController:someuiview3 animated:NO];

[someuiview release];[someuiview2 release];[someuiview3 release];

tabcontroller.viewControllers=[NSArray arrayWithObjects:navcon, navcon2, navcon3, nil];
[navcon release]; [navcon2 release]; [navcon3 release];

someuiviewn are subclasses of UIViewControllers (maybe UITableViewControllers for example (or whatever :))
