You have to install ' LG TV remote' app from AppStore and make sure that both TV and your iDevice are connected to same wi-fi network. Launch the app and it should find the TV. There're two different apps in the AppStore for lg TV remote. Try both in case you're not able to one of them to work. Good luck.
