導航控制器在選項卡控制器不顯示返回按鈕

我有一個選項卡控制器與2個選項卡「我的信息」和「他們的信息」，這只是一堆文本框。我想在頂部導航控制器，這樣我就可以回去，但後退按鈕不會顯示出來...這裏是我的代碼：導航控制器在選項卡控制器不顯示返回按鈕

按下按鈕顯示形式：

-(IBAction)onIncidentAidFormPressed:(id)sender { 
    FormController *aidForm = [[FormController alloc] initWithNibName:@"formController" bundle:nil]; 
    aidForm.managedObjectContext = self.managedObjectContext; 
    [self.navigationController pushViewController:aidForm animated:YES]; 
}

在的FormController .M - （ID）initWithNibName：（的NSString *）nibNameOrNil包（一個NSBundle *）nibBundleOrNil：

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
if (self) { 
    self.title = NSLocalizedString(@"Aid Form", @"Aid Form title"); 
} 
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
UIViewController *viewController1 = [[MyInformationController alloc] initWithNibName:@"MyInformationController" bundle:nil]; 
UIViewController *viewController2 = [[TheirInformationController alloc] initWithNibName:@"TheirInformationController" bundle:nil]; 
UINavigationController *navController = [[UINavigationController alloc] initWithNibName:@"navController" bundle:nil]; 

[navController pushViewController:viewController1 animated:YES]; 

self.tabBarController = [[UITabBarController alloc] init]; 
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController, viewController2, nil]; 
self.window.rootViewController = self.tabBarController; 
[self.window makeKeyAndVisible]; 
return self;

的標籤正確顯示和導航欄是有，但沒有後退按鈕顯示取回。

編輯：這裏有文件：IncidentAidStartViewController.h

你可以在這裏找到我的答案http://stackoverflow.com/questions/10229805/i-want-to-use-both-tab-bar-and-navigation-bar-in-same-view-控制器/ 10229914＃10229914 – Charan 2012-04-20 14:39:50

發佈你想要顯示的按鈕上的那些視圖控制器文件的一些代碼。例如。當在MyInformationController選項卡上點擊一些按鈕（可能是backgroundButton，我猜）;你會看到一個新的觀點。發佈你想要插入返回按鈕的「新視圖」文件的代碼。 – 2012-04-20 18:51:26

我通過將導航控制器添加到選項卡控制器來實現它的功能！感謝您的幫助 – user1154920 2012-04-20 21:01:24

到目前爲止，我知道這是增加的好方法你們六ews to tabbar。所以試試這個

UIViewController *viewController1 = [[MyInformationController alloc] initWithNibName:@"MyInformationController" bundle:nil]; 
UIViewController *viewController2 = [[TheirInformationController alloc] initWithNibName:@"TheirInformationController" bundle:nil]; 
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1]; 
UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:viewController2]; 

self.tabBarController = [[UITabBarController alloc] init]; 
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController1, navController2, nil];

要添加回欄項目，下面的ine也被使用。

self.navigationItem.leftBarButtonItem = self.navigationItem.backBarButtonItem;

我在寫信之前沒有看到您的答案。你應該知道，當有人給出答案時，瀏覽器不會刷新。那我怎麼看到你的答案？你爲什麼降低我的聲譽??????? – sandy 2012-04-20 15:04:56

可能是你的互聯網不是很快..「不要忘了，這個網站是非常快速的，每隔幾秒給予udates」。在你完成之前，當你鍵入答案並且某人已經發布時，那麼它會通過橙色閃光提醒你有人發佈了答案。即使你編輯帖子你會得到相同的閃光效果通知有關變化。 – 2012-04-20 15:09:41

downvote原因在評論 - >「initWithRootViewController」中出現錯誤。它是一個NSSting，但viewContrller實例 – 2012-04-20 15:11:53

-1

應替換爲以下代碼：

UIViewController *viewController1 = [[MyInformationController alloc] initWithNibName:@"MyInformationController" bundle:nil]; 
UIViewController *viewController2 = [[TheirInformationController alloc] initWithNibName:@"TheirInformationController" bundle:nil]; 
UINavigationController *navController1 = [[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease]; 
UINavigationController *navController2 = [[[UINavigationController alloc] initWithRootViewController:viewController2] autorelease]; 

self.tabBarController = [[UITabBarController alloc] init]; 
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController1, navController2, nil];

讓我知道任何別的東西，你需要........

哎什麼的.. u必須抄我的答案我已經回答了這個問題...＆BTW「initWithRootViewController：」 u必須寫一個NSString的..所以downvote爲 – 2012-04-20 15:02:15

請修改你的方法是這樣

-(IBAction)onIncidentAidFormPressed:(id)sender 
{ 
    FormController *aidForm = [[FormController alloc] initWithNibName:@"formController" bundle:nil]; 
    aidForm.managedObjectContext = self.managedObjectContext; 
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:nil]; 
    [self.navigationController pushViewController:aidForm animated:YES];
