objective-c - 目标 C：标签栏控制器：如何选择标签并将视图集弹出到根目录？

Question

在我的通知确实接收方法中，我希望应用程序转到选定的选项卡并显示选项卡的根视图控制器。

我尝试了以下实现，但选定的选项卡没有显示根视图控制器。我怎样才能使这项工作？

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    self.tabController.selectedIndex = 2; 

    //Pop View Controller to root
   [self.tabController.selectedViewController.navigationController popViewControllerAnimated:NO];     
}

Answer 1

尝试

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    self.tabController.selectedIndex = 2; 

    //Pop View Controller to root
   [self.tabController.selectedViewController.navigationController popToRootViewControllerAnimated:NO];     
}
