私は現在、地図上に注釈を配置するために plist を使用しています。これを行うことはできましたが、地図ビューから詳細ビューに移動して plist から情報を取得しようとすると問題が発生します。
マップビューにタイトルとサブタイトルが含まれるように plist を設定しました。次に、子を設定しました。これは、詳細ビューでアクセスしようとしている情報に移動します。
詳細ビューに移動することはできましたが、それを行うために必要なコードを理解できないため、情報を取得しません。
私は少し混乱しているので、これがすべて意味をなすことを願っています。これについて誰か助けてくれてありがとう、あなたは命の恩人になるでしょう（一種の）
コードはこちら
