iOS insert View between Navigation Bar and View underneath it -

i want insert uiview between navigation bar , uiview (underneath navigationbar) show network connectivity status. view underneath nav bar should go downward make space indicatorview.

my code:

indicatorview = [[uiview alloc] initwithframe:cgrectmake(0, 0, view_width, 35)]; [self.view addsubview:indicatorview]; self.view.frame = cgrectmake(0, 35, view_width, view_height - 35);
