UINavigationController動畫

Question

我有一個tabBar應用程序與兩個選項卡。每個標籤都有自己的navigationController這種方式來實現：

FirstViewController *firstController = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil]; 
UINavigationController *firstNavController = [[UINavigationController alloc] initWithRootViewController:firstController]; 

SecondViewController *secondController = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; 
UINavigationController *secondNavController = [[UINavigationController alloc] initWithRootViewController:secondController]; 

tabBar.viewControllers = [NSArray arrayWithObjects:firstNavController, secondNavController, nil]; 

當我要推一個視圖到一個選項卡我用這個：

[self.navigationController pushViewController:activityController animated:YES]; 

，當我在推看法，我想彈出我使用的視圖：

[self.navigationController popViewControllerAnimated:YES]; 

推動畫作品不錯，但在彈出動畫只有頂部欄（NavigationController）獲取動畫和視圖，而無需動畫消失。什麼可能是錯誤的？

Answer 1

嘗試使用而不是[self.navigationController popViewControllerAnimated:YES]; [self.navigationController popToRootViewControllerAnimated:YES];

，並告訴我，如果這個工程。記住netsted導航控制器。
