objective-c - フォーマット指定エラー

Question

エラーメッセージが表示されます：expected ':'おそらくinitWithTitle:@"You downloaded %i boards", iboard以下のフレーズが原因です。修正を手伝ってもらえますか？

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"You downloaded %i boards", iboard message:@"Press Ok to continue" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];

Answer 1

交換

initWithTitle:@"You downloaded %i boards", iboard 

と

initWithTitle:[NSString stringWithFormat:@"You downloaded %i boards", iboard]

Answer 2

コードをめちゃくちゃにしました。

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"You downloaded %i boards", iboard message:@"Press Ok to continue" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];

そのはず ：

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"You downloaded %i boards", iboard]
                                                message:@"Press Ok to continue" 
                                               delegate:self 
                                      cancelButtonTitle:@"Ok" 
                                      otherButtonTitles:nil];
