Remove tab bar item text, show only image

Question

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:

Answer 1

I used the following code in my BaseTabBarController's viewDidLoad. Note that in my example, I have 5 tabs, and selected image will always be base_image + "_selected".

// Get tab bar and set base styles
let tabBar = self.tabBar;
tabBar.backgroundColor = UIColor.whiteColor()

// Without this, images can extend off top of tab bar
tabBar.clipsToBounds = true

// For each tab item..
let tabBarItems = tabBar.items?.count ?? 0
for i in 0 ..< tabBarItems {
    let tabBarItem = tabBar.items?[i] as UITabBarItem

    // Adjust tab images (Like mstysf says, these values will vary)
    tabBarItem.imageInsets = UIEdgeInsetsMake(5, 0, -6, 0);

    // Let's find and set the icon's default and selected states
    // (use your own image names here)
    var imageName = ""
    switch (i) {
    case 0: imageName = "tab_item_feature_1"
    case 1: imageName = "tab_item_feature_2"
    case 2: imageName = "tab_item_feature_3"
    case 3: imageName = "tab_item_feature_4"
    case 4: imageName = "tab_item_feature_5"
    default: break
    }
    tabBarItem.image = UIImage(named:imageName)!.imageWithRenderingMode(.AlwaysOriginal)
    tabBarItem.selectedImage = UIImage(named:imageName + "_selected")!.imageWithRenderingMode(.AlwaysOriginal)
}
