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

In my case, same ViewController was used in TabBar and other navigation flow. Inside my ViewController, I have set self.title = "Some Title" which was appearing in TabBar regardless of setting title nil or blank while adding it in tab bar. I have also set imageInsets as follow:

item.imageInsets = UIEdgeInsets(top: 6, left: 0, bottom: -6, right: 0)

So inside my ViewController, I have handled navigation title as follow:

if isFromTabBar {
   // Title for NavigationBar when ViewController is added in TabBar
   // NOTE: Do not set self.title = "Some Title" here as it will set title of tabBarItem
   self.navigationItem.title = "Some Title"
} else {
   // Title for NavigationBar when ViewController is opened from navigation flow
   self.title = "Some Title"
}
