How do I add a featured iTunes Radio station to my stations on iOS? On iTunes for Mac I can right click a station to add it my stations. I tried a long press on a featured station on iOS but that doesn't bring up any options.
According an Apple support doc:


  You can add a featured station to My Stations by tapping the Info (i)
  button, then tapping the Plus (+) button to the right of "Add to My
  Stations."
