  1. POHidden UINavigationController inside UITabBarController
    text
    copied!<p>I have an application with 5 <code>UIViewController</code>s each inside a corresponding <code>UINavigationController</code>, all tucked inside a <code>UITabBarController</code> that displays 5 tabs at the bottom of the screen.</p> <p>I want to display another <code>UIViewController</code> (inside a <code>UINavigationController</code>) when a dialog button is pressed.</p> <p>This view should only be loaded and unloaded programatically; i.e. it should not appear in the tab bar. However, I want the tab bar to be visible always.</p> <p>If I add the <code>[UINavigationController view]</code> to <code>[self window]</code> the <code>UITabBar</code> is covered. If I add it to any other layer, the <code>UINavigationController</code> adds on the compensation it has for the status bar so appears further down than expected.</p> <p>A solution would be to have the 6th <code>UINavigationController</code> added to the <code>UITabBar</code> with the others, but with its <code>tabBarItem</code> hidden. Then I can show it and hide it using the <code>tabBar</code>s <code>selectedIndex</code> property.</p> <p>Accessing the <code>tabBarItem</code> through the <code>UIViewController</code> shows no obvious way of doing this.</p> <hr> <p>@wisequark, I think you completely misunderstood and you have almost rewritten the architecture of my application. However I have a separate navigation controller for each view as they are mutually exclusive and there is no concept of "drilling down".</p> <p>@Kendall, This is what I expect I will have to do - have the modal view appear with a hide button to bring back the normal interface. But it would be nice to keep the tab bar always visible, so I was just wondering if anyone knew of a way.</p>
