title: Tabbar Images Cut
body: <p>I am using tabcontroller. In the first image screenshot got from storyboard, the second one got from the app on the iphone. Once you look closer to the images in the second image, you could see images are cut at the bottom compared to first screenshot tabbar images. I do not have any idea why this happened.</p>
