I read this question about adding a 'more' button to the tab bar. It says if we add a 5th button, the tab bar controller will automatically add a 'more' button. But, in XCode 4 , adding a new tab to the tab bar is different and so it doesn't take the 5th button as a 'more' button'.
What do I have to do to add a 'more' button to the tab bar?
