Updating UILabel and clearing it? - objective-c

Question

I have a UILabel that I start at "0" and then as my game progresses I call the below code to add "1" to the score each time a button is pressed. This all works fine.
playerOneScore.text = [NSString stringWithFormat:#"%d",[playerOneScore.text intValue]+1];
My problem is that when the game ends and the user presses the "Replay" button. This replay button sets the label back to "0" by calling this.
playerOneScore.text = #"0";
But then when the game progresses my label jumps from "0" to where it had initially left off + 1. What am I doing wrong here? Not making sense.
Any help would be very grateful! Thank you!
More code requested (simplified):
- (void)viewDidLoad
{
playerOneScore.text = #"0";
}
-(IBAction)touchDown {
if (playerOneTurn == YES) {
if (button1.touchInside == YES) {
playerOneScore.text = [NSString stringWithFormat:#"%d",[playerOneScore.text intValue]+1];
}
}
}
-(void) replayGame {
playerOneScore.text = #"0";
}

Not sure what's going on, but I would suggest using a separate NSInteger property to track the score. Then override the property setter to update the label text.
Add the property to your interface or a private category:
#property (nonatomic, assign) NSInteger score;
Then override the setter:
- (void)setScore:(NSInteger)value {
_score = value;
playerOneScore.text = [NSString stringWithFormat:#"%d", value];
}
Then in your action, update the score and label using the new property:
-(IBAction)touchDown {
if (playerOneTurn == YES) {
if (button1.touchInside == YES) {
self.score += 1;
}
}
}
Note that I haven't compiled or tested this code, but it should be close.
EDIT: fixed typo in setter
