Scoring in Turn Based Games

[keyvisuals]

Hi, I've been following an excellent tutorial on Turn Based Gaming . . .
Beginning Turn Based Gaming with iOS 5 Part 2 | Ray Wenderlich

I'm able to handle scoring ok as long as there is only one match going on, but as soon as I start/join another match things go wrong.

For simplicity i've just been trying to add +1 to the players score every time they take a turn.

I've been using this to keep score for the current player:

self.currentScore = self.currentScore + 1;
currentScoreLabel.text = [NSString stringWithFormat: @"%ld", self.currentScore];

When I change to a different match the score for the previous match persists ;(

I'm sure my overly simplistic method of scoring is not ideal but that's why i'm following a tutorial Can someone show how to better handle this?

I imagine the best place to be is in your game set up code to reset the self.currentScore;

I'd recommend a reset too
