title: UITabBarItem setFinishedSelectedImage: deprecated in iOS7
body: <p><code>setFinishedSelectedImage:withFinishedUnselectedImage:</code> is deprecated in iOS7. Apple <a href="https://developer.apple.com/library/ios/documentation/uikit/reference/UITabBarItem_Class/DeprecationAppendix/AppendixADeprecatedAPI.html">recommends</a> to use setters of <code>image</code> and <code>selectedImage</code>  with <code>UIImageRenderingModeAlwaysOriginal</code> instead. I can't find any example of how to use <code>UIImageRenderingModeAlwaysOriginal</code>. So the question is really simple: how to set images for <code>UITabBarItem</code> in iOS7?</p>
