目标C：Tabbar控制器：如何选择选项卡并将视图集弹出为root？

Question

在我的通知确实收到方法，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，但所选标签未显示根视图控制器。我怎样才能做到这一点？

-(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];     
}
