        }
    } @catch (NSException * e) {
//      NSLog(@"Problem in keyboardWillShow:%@",e);
    }

}

しかし、このコードはiphone sdk 3.0で機能しますが、このコードはiphone SDK 4.0では機能しません.uikeyboardバウンスユーザー情報キーはiphone 4.0 OSでは非推奨です.完了ボタンのあるツールバーを作成しません.どうすればそれを行うことができるか教えてください.

あなたはで試すことができます

if ([[currentWindow description] hasPrefix:@"<UITextEffectsWindow"])
        {
            NSLog(@"Key board found");
}

でも、隠すことはできないと思います。カスタム ビューを配置できますがUIKeyboard、iOS 4 では機能しないと思います。
