问题描述

我有一个带有 4 个视图/选项卡的 UITabBarController.每个视图都是一个 UINavigationController.

I have a UITabBarController with 4 views/tabs. Each view is a UINavigationController.

如何在这些 UINavigationControllers 之一上 popToRootViewController 然后切换选项卡并将 viewController 推送到另一个 UINavigationController 上使用动画贯穿始终?

How can I popToRootViewController on one of these UINavigationControllers then switch tabs and push a viewController onto another UINavigationController using animation throughout?

所以顺序是:

开始时,我们在 Tab 1 的视图中,这是一个 UINavigationController.一个视图被推到它的根视图控制器之外.

At start we are in Tab 1's view which is a UINavigationController. A View has been pushed onto it beyond its root ViewController.

-Tab 1
   - UINavigationController1
      - RootViewController1
      - SomeViewController1 [We are here]

-Tab 2
   - UINavigationController2
      - RootViewController2

在 SomeViewController1 中点击一个按钮会导致以下情况:

A button is tapped in SomeViewController1 that causes the following:

  1. UINavigationController1 弹出到其根视图控制器(带动画)
  2. UITabBarController 将 tab 切换到 Tab2
  3. SomeViewController2 被推送到 UINavigationController2(带动画)

所以视图看起来像这样:

So the view looks like this:

-Tab 1
   - UINavigationController1
      - RootViewController1

-Tab 2
   - UINavigationController2
      - RootViewController2
      - SomeViewController2 [We are here]

推荐答案

int tabYouWantToSelect=2;
BOOL isNavigation=YES;
[[self.tabBarController selectedViewController].navigationController popToRootViewControllerAnimated:YES];

//if any controller is presented as a model view then
//[[self.tabBarController selectedViewController] dismissModalViewControllerAnimated:YES];

[self.tabBarController setSelectedIndex:tabYouWantToSelect];

//the newly pushed view controller's viewWillAppear
-(void)viewWillAppear:(BOOL)animated {
        if(isNavigation){
            [self.navigationController pushViewController:objAddLocation animated:YES];
         }
}
