title: iOS: Implementing UITabBar from User Interface without a UITabBarController
body: <p>In my app I have a UIViewController to which I wish to add a UITabBar. So I have added it via User Interface (into the UIViewController.xib file) and created instances of the IUTabBar and the UITabBarItems within the UIViewController.h+m files. in the xib file I was able to connect the code items to the ones on the xib (by dragging from the File Owner to the relevant item and selecting the relevant IBOutlet) but I cannot seem to connect back the buttons to the IBActions written on the h+m files.</p>
  
  <p>Before adding the UITabBar I worked with a UIToolBar and had no problem doing these connections.</p>
  
  <p>Can anyone explain what am I doing wrong? </p>
