I'm making a Hangman app in objective-c and want to include a statistics page which has stats on games played, games won, etc. I have 4 view controllers connected to their own .m files. One for the home page, one for single player, one for multiplayer, and one for statistics. How do you get information across one view controller to the other?
For example, if the user lost a game, how can I get that information across from the single player view controller to the statistics page?
(I can't include view controllers so I don't really know what code to include.)
