Add this method to your frame to register multiple events.

Code Edit

local function UnregisterEvents(self, ...)
	for i=1,select('#', ...) do
		self:UnregisterEvent(select(i, ...))
	end
end

Example Edit

local frame = YourEventFrame
frame.UnregisterEvents = UnregisterEvents

-- Tell the API to stop listen for 'VARIABLES_LOADED', 'ADDON_LOADED', and 'MERCHANT_SHOW'
frame:UnregisterEvents('VARIABLES_LOADED', 'ADDON_LOADED', 'MERCHANT_SHOW')

Or unregister events for a frame without attaching UnregisterEvents to the frame:

local frame = YourEventFrame

-- Tell the API to stop listen for 'VARIABLES_LOADED', 'ADDON_LOADED', and 'MERCHANT_SHOW'
UnregisterEvents(frame, 'VARIABLES_LOADED', 'ADDON_LOADED', 'MERCHANT_SHOW')
