bascily

    int playerscore = [_txt_score.text intvalue];     int gamescore = 501;     int currentscore = gamescore - playerscore;

when clicked done button second time processes start on want manipulate gamescore value, not it.

1) create variable value in appdelegate.h file @propertise , @synthesise it

2) set value below: appdelegate *appdelegate = [[uiapplication sharedapplication] delegate]; appdelegate.value -= 5;
