title: setTitleView strange behaviour in iOS 5 - objective-c
body: <p>I try to set <code>UILabel</code> as <code>titleView</code> using <code>[self.navigationItem setTitleView:musicArtist];</code> method, but it works strange with different iOS versions. UINavigationBar is in <code>UIPopoverController</code>.
