def handle_event(event)
  trigger_changed(event)
end

#on(control_event, options = {}, &block) ⇒ Object

control_event can be any UIControlEventConstant, or any symbol found in wiretap_control_events.rb, or an array of UIControlEventConstants or symbols. Since UIView implements ‘on` to accept a gesture, this method calls `super` when the symbol isn’t a control
