iphone - 带有动画的 popToRootViewController 然后切换选项卡

Question

我有一个带有 4 个 View /选项卡的 UITabBarController。每个 View 都是一个 UINavigationController。

如何在其中一个 UINavigationController 上弹出 ToRootViewController 然后切换选项卡并将 viewController 推送到另一个使用动画的 UINavigationController？

所以顺序是:

一开始我们在 Tab 1 的 View 中，它是一个 UINavigationController。一个 View 已被推送到其根 ViewController 之外。

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

-Tab 2
   - UINavigationController2
      - RootViewController2

点击 SomeViewController1 中的按钮会导致以下情况:

1. UINavigationController1 弹出到它的 Root View Controller (带有动画)
2. UITabBarController 将选项卡切换到 Tab2
3. SomeViewController2 被推送到 UINavigationController2(带动画)

所以 View 看起来像这样:

-Tab 1
   - UINavigationController1
      - RootViewController1

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

Answer 1

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];                
         }
}
