Restore an Objective-C method signature from MacRuby's automatic Ruby-style conversion (such as that passed to method_missing)

restoreObjcMethodSignature.rb

# Takes an Objective-C method signature, automatically converted to "Ruby-style" by MacRuby, and restores it.
# Restored method and arguments are returned in an array.
def restoreObjcMethodSignature(method, args)
	if ((args.length == 2) && (args[1].is_a? Hash))
		method = method+':'+args[1].keys.join(':')
		args = [args[0], *args[1].values]
	end
	[method, args]
end

# Example usage
def method_missing(method, *args)
	newMethod, newArgs = restoreObjcMethodSignature(method, args)
	if @cocoaObject.respond_to?(newMethod)
		@cocoaObject.send(newMethod, *newArgs)
	else
		super
	end
