私は自分のアプリを特定の無人機に接続することはできません。私はブリッジ・アプリをダウンロードして、それを使ってデバッグしています。サンプルアプリケーションから "DJIBaseViewController"をコピーして、自分のView Controllerをその代理人にしました。多くのブレークポイントをコードに追加した後、私のアプリケーションとサンプルアプリケーションの主な違いは、デリゲートメソッド "sdkManagerProductDidChange"です。DJIドローンが接続されていません（sdkManagerProductDidChangeデリゲートメソッドが呼び出されません）

sdkManagerは、指定されたアプリキーとバンドラ識別子で正しく登録されています。私はまた、3つの要素、com.dji.video、com.dji.protocol、およびcom.dji.commonで、 "サポートされている外部アクセサリプロトコル"をinfo.plistファイルに追加しました。
かなり長い間ここにこだわってきたことがありました。誰かが助けを呼ぶことを望む。
ありがとうございます。
