私は検索バーでtableviewを使用しています.jsonはサーバーから正しくフェッチしています。私の検索ビューバーのデータが表示され、それがフィルタリングされて、私のテーブルビューに正しく表示されているにもかかわらず、私は一見のためにviewcontrollerを開くと、データが私のテーブルビューにロードされていません。 誰も私にここで何が問題になるのか教えてもらえますか？ 開いているときにjsonデータ全体を読み込むようにtableviewします。 NSURLSession completionHandlerブロック内[self.residentListTableView reloadData];を入れ、ここviewcontrollerが最初に読み込まれたときにテーブルビューが読み込まれない

ありがとうございます@nynohu。私は以下のコードを解決しました。 – Shelby
