The difference is specific vs. unspecific type.

  • Use the specific type if only this particular UI element is supposed to call the method and you need to process properties like title or tag of the passed sender.
  • Use the unspecific type if the method can be called from different places with different sender types or if the sender parameter is not used at all.
