Question

Help Please. Everytime when I touch my UIButton, my label should increase existing number (1,2,3,4…) if my UIImageView.image = image1.png and I press at that time my UIButton, my label should decrease -10. Decreasing and Increasing works, but if I deacrease for example from 34 to 24, next time when i press to increase, it increase from 34 not from existing 24.

Here is my code:

if (UIImageView.image == [UIImage imageNamed:@"image1.png"]) {
        NSString *dataMinus = [NSString stringWithFormat:@"%i",scoreIncrease - 10];
        [self.label setText:dataMinus];
    }

    else {

        NSString *dataToSend = [NSString stringWithFormat:@"%i",scoreIncrease++];

        [self.label setText:dataToSend];

      }

Help to fix that, please.
