            iid = iid-41;
            int rr = 401900;
            rr++;
            rr = rr+iid;

            [(UIImageView*)[self.view viewWithTag:rr] setImage:[UIImage imageNamed:imageTitle]];
            iid++;
        }

        ids++;
    }

この特定のコード行でコードが失敗します...（forループの終わりに向かって）

[(UIImageView*)[self.view viewWithTag:iid] setImage:[UIImage imageNamed:iconNum]];

エラーが発生するため、意味がありません-（UILabel setImage）コードでUIImageViewを明確に使用している場合???

これがデバッガーでnslogされるものです...

タグ 71 または 72 を持つ UILabel のストーリーボードまたは nib を確認します。本当に問題がある場合は、見つけやすくするためにプログラムで追跡することもできます。

UILabel *labelToChange = (UILabel *)[self.view viewWithTag:71];
labelToChange.backgroundColor = [UIColor greenColor];

あなたがそれに取り組んでいる間に、最初の大きな長いスイッチを単純なワンライナーに変更してみませんか?

if (sint > 0 && sint < 10) iconNum = [NSString stringWithFormat:@"Num%d.png", sint];
