# Stupid hack because the RubyMotion dependency detection has a bug.

    # Looks like RubyMotiononly  adds UIKit constants
    # at compile time. If you don't use these
    # directly in your code, they don't get added
    # to Kernel and Constants.get crashes.
    # Examples
    # Constants.register UIReturnKeyDone, UIReturnKeyNext
    def register(*ui_constants)
      # do nothing, just get the constants in the code
    end

    # @param [String] base of the constant
    # @param [Integer, NSArray, String, Symbol] the suffix of the constant
    #   when NSArray, will return the bitmask of all suffixes in the array
    # @return [Integer] the constant for this base and suffix
    # Examples
    # get("UIReturnKey", :done) => UIReturnKeyDone == 9
    # get("UIReturnKey", "done") => UIReturnKeyDone == 9
    # get("UIReturnKey", 9) => 9
    # get("UIImagePickerControllerSourceType", ["photo_library", "camera", "saved_photos_album"]) => 3
    # get("UIActivityType", [:air_drop, :print]) => ["com.apple.UIKit.activity.AirDrop", "com.apple.UIKit.activity.Print"]
