回答1:
You can setup UINavigationController with an initial navigation stack via setViewControllers:animated:.
// in application:didFinishLaunchingWithOptions:
self.navigationController = [[UINavigationController new] autorelease];
UIViewController *first = [[MyFirstViewController new] autorelease];
UIViewController *second = [[MySecondViewController new] autorelease];
NSArray *controllers = [NSArray arrayWithObjects:first, second, nil];
[navigationController setViewControllers:controllers animated:NO];
...
[window addSubview:navigationController.view];
回答2:
Initialise your navigation controller on startup programmatically with 2 controllers already in stack:
FirstViewController *first = ...//create controller
SecondViewController *second = ...//create controller
[navigationController setViewControllers:[NSArray arrayWithObjects:first, second, nil]
animated:NO];
Or alternatively you can make your 1st controller push the second one on startup - see Apple's DrillDownSave sample for that technique.

Follow somesteps as:
1.open the MainWindow.xib in resource folder or bundle.
2.click on Tool and open Inspector >> choose attribute >> NIB Name-set here your view name from drop down list >> identity in inspector(from upper tabs) >> choose class -set here your view name again from drop down list.
3.Open appdelegate.m file
change here the view controller as : fileviewcontrollername *viewController;
set it's property.
4.in didFinishLaunching in appdelegate.m add
UINavigationController *navController=[[UINavigationController alloc]initWithRootViewController:viewController];[window insertSubview:navController.view];[self.window makeKeyAndVisible];return YES;
5.In appdelegate.h file add
@class viewControllername;
