title: UITabBarController does not respond on iPhone 5 simulator: 4-inch retina display
body: <p>I have a UITabBarController that displays four options. These have all worked fine until now.</p>
  
  <p>My problem is that the tab bar does not respond only when testing on the 4-inch retina display device in the IOS Simulator. All other devices the tab bar responds and I am able to select other views.</p>
  
  <p>I don't have an iPhone 5 to test it on so I don't know if this is a fault with the simulator or Apple have changed the workings of tab bars etc for the new hardware or made it stricter and I wrote the wrong code in the first place.</p>
