このテーブルビューにアクセサリ (チェックされている/チェックされていない) を追加しようとしていますが、何らかの理由で xCode が次の行に何か問題があると言っています: [item setObject:cell forKey:@"StrainTableCell"];
コンソールに次のエラーが表示されます。
*キャッチされない例外 'NSInternalInconsistencyException' が原因でアプリを終了します。理由: '-[__NSCFDictionary setObject:forKey:]: 変更メソッドが不変オブジェクトに送信されました'*
誰かが理由を知っていますか?以下のコード スニペットを参照してください。
