如何添加navigationcontroller到的UIViewController

employeeDetailed = [[[EmployeeDetailedViewController alloc] initWithNibName:@"EmployeeDetailedViewController" bundle:nil] autorelease]; 
    UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:employeeDetailed] autorelease]; 
    [employeeDetailed release]; 
    [self.navigationController pushViewController:navController animated:YES];

我試試這個它說壞的訪問。[碰撞]如何添加navigationcontroller到的UIViewController

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  

    // Override point for customization after application launch. 
    // Set the view controller as the window's root view controller and display. 
    UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:self.viewController] autorelease]; 
    self.window.rootViewController = navController; 
    [self.window makeKeyAndVisible]; 

    return YES; 
} 



employeeDetailed = [[[EmployeeDetailedViewController alloc] initWithNibName:@"EmployeeDetailedViewController" bundle:nil] autorelease]; 

[self. navigationController presentModalViewController: navController];

這會爲你工作試試這個。

其爲我工作的感謝！ – kiran 2012-01-10 14:06:37

你已經在第一線自動釋放設定（分配/初始化）

你是那麼明確地釋放在三線視圖控制器。

因此，您過度釋放此對象並導致崩潰。

您可以刪除[employeeDetailed發佈]行，它會沒事的。

@thanks IanL忘記內存問題。！你能幫我看看如何推ViewViewController它不推動我 – kiran 2012-01-10 13:26:40

正如鈹提到的，你不能推動一個新的UINavigationController到現有的導航堆棧。你指的是self.navigationController，所以我假設當前的控制器是堆棧的一部分。在這種情況下，您應該可以簡單地使用：[self.navigationController pushViewController：employeeDetailed animated：YES]; – 2012-01-10 13:37:47

yeap我使用[self.navigationController pushViewController：employeeDetailed animated：YES];控制器仍然沒有做任何事情！ – kiran 2012-01-10 13:44:07

您不能將UINavigationController添加到現有導航堆棧。相反的，你需要表現出新的導航控制器模式是這樣的：

employeeDetailed = [[[EmployeeDetailedViewController alloc] initWithNibName:@"EmployeeDetailedViewController" bundle:nil] autorelease]; 
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:employeeDetailed] autorelease]; 
[self presentModalViewController: navController];

我不想要presentmodalviewcontroller先生。我需要pushViewController – kiran 2012-01-10 13:27:23

，然後只推'employeeDetailed'，沒有'navController'。 – beryllium 2012-01-10 13:39:13

yeap我做了它不工作！ – kiran 2012-01-10 13:46:28

我發現呈現導航控制器在應用程序的特定部分的最佳方式是這樣的：

MyViewController *myViewController = [[MyViewController alloc]initwithnibname :@"MyViewController"]; 
    UINavigationController *myNavC = [[UINavigationController alloc]initWithRootViewController:myViewController];

在myViewController.m

然後使用

[self.NavigationController pushViewController: XController animated:YES];
