如何在不触摸标签的情况下切换到UITabBar的另一个标签? [英] How to switch to another tab of UITabBar without touching a tab?

问题描述

我有一个选项卡栏设置，我希望能够让用户更改选项，并且在选择了最后一个选项或通过按视图上的按钮后，能够自动切换到另一个选项卡.

I have a tab bar setup and I want to be able to let the user change options and after the last one is selected or by pressing a button on the view, be able to automatically switch to another tab.

简单来说，我有4个选项卡设置，在一个选项卡上，我选择一个选项或按一个按钮，然后希望它切换到另一个选项卡.我在主窗口上有一个标签栏，并有4个单独的视图，每个视图都是一个nib文件.

Simply, I have 4 tabs setup and on one, I pick an option or press a button and I want it to switch to the other tab. I have the tab bar on the main window and 4 separate views, each as a nib file.

推荐答案

确定要在此处使用TabBarController而不是NavigationController吗?对于TabBar，您要查找的答案是设置-selectedViewController或-selectedIndex.对于您列出的特定情况，-selectedIndex可能是最好的选择.

Are you sure you want a TabBarController here and not a NavigationController? For TabBars, the answer you're looking for is to set -selectedViewController or -selectedIndex. For the specific case you list, -selectedIndex is probably your best bet.
