Remove text from Back button keeping the icon

Question

I want to remove the text from the back button, but I want to keep the icon. I have tried

let backButton = UIBarButtonItem(title: \"\", style: UIBarButtonIt         


        

Answer 1

Sometimes its not working to change only the title color, in case when the title is long. Because it might shift the navigation bar title to the left. So to prevent it you might need to shift the bar button title horizontally in addition to make it transparent:

let barButtonItemAppearance = UIBarButtonItem.appearance()
    barButtonItemAppearance.setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.clear], for: .normal)
    barButtonItemAppearance.setBackButtonTitlePositionAdjustment(UIOffsetMake(-200, 0), for:UIBarMetrics.default)
