iphone - Why is my UINavigation controller off by 79 pixels -

in iphone works great.

however when @ navigationbar frame -44? iphone y origin 0.

is supposed this? seems shifted 79 pixels.

any idea how fix?

when rotate sizes ok initial landscape size wrong.

adding view code fixes not want do: navigationcontroller.view.superview.frame = cgrectmake(-79, 0, size.width, size.height);

startravelappdelegate *appdelegate = (startravelappdelegate *)             [[uiapplication sharedapplication] delegate];      firstmenuview *firstmenuview = [[[firstmenuview alloc] init] autorelease];     // bac123viewcontroller *bac123 = [[bac123viewcontroller alloc] autorelease];     // uinavigationcontroller *navigationcontroller;    // appdelegate.navcontroller = [[[uinavigationcontroller alloc] initwithrootviewcontroller:firstmenuview] autorelease];      mynavigationcontroller *navigationcontroller = appdelegate.navcontroller;     [navigationcontroller pushviewcontroller:firstmenuview animated:true];      cgsize size = [[ccdirector shareddirector] winsize];      navigationcontroller.view.superview.frame = cgrectmake(-79, 0, size.width, size.height);     // uiview *view = [[ccdirector shareddirector] view];     // [view addsubview:bac123.view];    //  [view addsubview:navigationcontroller.view];     navigationcontroller.navigationbarhidden = true; 

the app delegate:
