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:

Based on the answer of ddiego, in Swift 4.2:

extension UITabBarController {
    func cleanTitles() {
        guard let items = self.tabBar.items else {
            return
        }
        for item in items {
            item.title = ""
            item.imageInsets = UIEdgeInsets(top: 6, left: 0, bottom: -6, right: 0)
        }
    }
}

And you just need to call self.tabBarController?.cleanTitles() in your view controller.
