When hiding and later unhiding the backButton (not a regular left/rightBarButtonItem) in the NavigationBar via navigationItem.hidesBackButton = true/false the text gets truncated in the middle.
Set the Text Size (dynamic font size) of your phone to the smallest value (or second smallest) otherwise it doesn't work.
Example: The back button shows the title of the previous controller, e.g. < Settings. After hiding and showing it the back button again it now says < Se...gs
Is there any known workaround?
