title: Enforce static title in UITabBar
body: <p>I am using a <code>UITabBar</code> whose first tab relates to a <code>UINavigationController</code>. The <code>UINavigationController</code>'s root view controller's <code>viewWillAppear:</code> sets that view controller's (and hence the navigation controller's) title to the current month symbol. This implicitly also changes the title shown in the tab bar.</p>
  
  <p>How can I achieve an alternative situation where the tab bar shows a static title (e.g. <code>"Calendar"</code>) whereas its related navigation controller still shows the dynamic one (e.g. <code>"December"</code>)?</p>
