無効なトークンがあると、iOSデバイスへのプッシュ通知が失敗する

Question

プッシュ通知を送信すると、無効なデバイスID（トークン）に当たってプッシュ通知が送信を停止するまで正しく動作します。

など。したがって、無効なトークンが配列の先頭にあった場合、残りのデバイスは通知を受けません。

これをやめる方法や無効なトークンをどのように処理するべきか、誰にも分かりますか？

無効なトークン：

1. あなたは無効なトークンを送信したときに発生するエラーを処理する必要がありますあなたがフィードバックサービス（feedback.push.apple.com）から無効なトークンを処理し、あなたのトークンのリストからトークン

は、あなたのコード例は、」doesnのことを削除する必要があり、次のトークン

を送信し続けますこれらのことを心配しているので、それが働くのを止めるのです。
