UIViewController isn't displayed how it appears in interface builder

Question

I'm having a problem with my view shifting down when I load my app. In interface builder it looks like:

But when I load the app on the iPod it looks like:

I'm not really concerned with why it isn't showing the grey background in interface builder, I set that and it's working. But I don't understand why the view is shifting down. I verified that I'm not changing the view's bounds or anything in my viewController. I'm just running [super viewDidLoad]; in my viewDidLoad.

I realize you can't see the frame or anything but I can answer any questions you have about the interface builder file.

Here's my didFinishLoading from my AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
    UINavigationController *navcon = [[[UINavigationController alloc] init] autorelease];
    [navcon pushViewController:[[GTSpotViewController alloc] init] animated:YES];
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    self.window.rootViewController = navcon;
    [self.window makeKeyAndVisible];
return YES;
}

Answer 1

You are adding your view controller to a UINavigationController. In this case, it will not look identical to how you view it in IB. Try setting the rootViewConroller directly to your viewcontroller.

Answer 2

你可以看看在属性检查器并设置顶部栏导航栏，然后一切都会正常排队。

Answer 3

while designing vies in IB therebia an option to set/keep space for navbar/toolbar in the inspector. try setting those values. alos check the resizing option.

Answer 4

Maybe are there two Navigation controller. check the xib to see if there's a Navigation controller.

Answer 5

事实证明，我的iPod上有一个旧版本，该版本以某种方式影响了构建，因为我清除了它，现在不再有任何变化。
