Remove tab bar item text, show only image

Simple question, how can I remove the tab bar item text and show only the image?

I want the bar items to like in the instagram app:

enter image description here

In the inspector in xcode 6 I remove the title and choose a @2x (50px) and a @3x (75px) image. However the image does not use the free space of the removed text. Any ideas how to achieve the same tab bar item image like in the instagram app?

Solution

You should play with imageInsets property of UITabBarItem. Here is sample code:

let tabBarItem = UITabBarItem(title: nil, image: UIImage(named: "more")
tabBarItem.imageInsets = UIEdgeInsets(top: 9, left: 0, bottom: -9, right: 0)

Values inside UIEdgeInsets depend on your image size. Here is the result of that code in my app:
