Why do navigation appear 20 pixels below status bar in the view?

Question

  (void)viewDidLoad {

     [super viewDidLoad];

     UINavigationController *naviController = [[UINavigationController alloc]init];

     [self.view addSubview:naviController.view];
}

If I add navigation controller in the view, it appears about 20 pixels below status bar. I want it appears just below status bar. How do I fix this?

You need to release the navigation controller when you're done - you have a memory leak. — deanWombourne, May 03 '11 at 14:35

Just set the frame for naviController.view

naviController.view.frame = self.view.frame;

DeclareUINavigationController in the app delegate's applicationDidFinishLaunching:

UINavigationController *navController = [[UINavigationController alloc] init];

[navController pushViewController:viewControllerOfYourExample animated:YES];

I think it works if I put the code in there. But I have put the code in the view. Because navigation have to appeare if I click the button. – user698200 May 03 '11 at 14:17

Assuming that you're adding your navigation bar at 0,0 then it looks like you're view isn't positioning correctly.

The easy fix is to move your bar to be at 0,-20

UINavigationController *naviController = [[UINavigationController alloc]init];
CGRect frame = [naviController frame];
frame.origin.y = -20;
[naviController setFrame:frame];
[self.view addSubview:naviController.view];

However, that's a hack.

Try something like this instead :

[[self view] setAutoresizesSubviews:YES];
UINavigationController *naviController = [[UINavigationController alloc]init];
[naviController setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleBottomMargin];
[self.view addSubview:naviController.view];

That might work?

The First works. Second does not work. View seems to start from (0, 20). I don't understand why. Thank you. — user698200, May 03 '11 at 14:59
