iPhone:TabBarController作为导航控制器的第二级 [英] iPhone: TabBarController as second level of Navigation Controller

问题描述

我是iPhone开发的新手.

I'm new to iphone development.

我已经阅读了有关在窗口上实现标签栏控制器(例如，作为应用程序的主控制器)的教程.但是，如何将标签栏控制器创建为可以由导航栏控制器调用的独立" UIViewController?

I've read tutorials about implementing a tab bar controller on the window (eg as the main controller for the app). But how can I create a tab bar controller as a 'standalone' UIViewController that can be called by a navigation bar controller?

基本上，我的导航栏控制器具有一个UIViewControllers数组，它将显示在表中，然后在用户选择一个项目时加载适当的视图/控制器.

Basically my navigation bar controller has an array of UIViewControllers that it displays in the table and then loads the appropriate view/controller when a user selects an item.

现在，我希望这些已加载的视图/控制器之一成为选项卡栏控制器.我该怎么办?

Now I want one of these loaded views/controllers to be a tab bar controller. How can I do this?

我不确定如何在应用程序委托中没有插座/实例的情况下独自创建标签栏控制器.

I'm not sure how to create a tab bar controller on its own without having an outlet/instance in the application delegate.

希望如此.谢谢.

推荐答案

尽管先前的答案是正确的，但我想指出苹果对此不满意:

Although previous answer was is correct, I'd just like to point out that Apple won't be happy with this:

您永远不想将标签栏控制器推入导航控制器的导航堆栈中.这样做会造成一种不寻常的情况，即只有当特定视图控制器位于导航堆栈的顶部时，选项卡栏才会出现.标签栏设计为持久性的，因此这种短暂的方法可能会使用户感到困惑.

You never want to push a tab bar controller onto the navigation stack of a navigation controller. Doing so creates an unusual situation whereby the tab bar appears only while a specific view controller is at the top of the navigation stack. Tab bars are designed to be persistent, and so this transient approach can be confusing to users.

阅读人机界面指南，您的应用可能因违反界面规则"而被拒绝.此外，您还必须手动处理所有vieWillAppear/Disappear等.我很确定还有另一种设计界面的方法.

Read Human Interface Guidelines, your app might be rejected for "breaking the interface rules". What's more, you'll also have to handle all the vieWillAppear/Disappear etc manually. I'm pretty sure there's another way of designing the interface.
