Push-Benachrichtigung an iOS-Geräte schlägt fehl, wenn ungültiges Token

Question

Beim Senden einer Push-Benachrichtigung funktioniert es richtig, bis es eine ungültige Geräte-ID (Token) trifft und die Push-Benachrichtigungen nicht mehr senden.

z. Wenn also das ungültige Token am Anfang des Arrays war, erhielten die übrigen Geräte keine Benachrichtigung.

Hat jemand eine Idee, wie man das stoppt oder wie ich mit den ungültigen Token umgehen soll?

ungültig token:

gültigen Tokens:

1. Sie erhöht behandeln sollten Fehler, wenn Sie einen ungültigen Token gesendet und weiter nächste Token

2. senden sollten Sie ungültige Token von Feedback-Service (feedback.push.apple.com) handhaben und entfernen, dass aus der Liste Ihrer Token-Token

Ihr Beispielcode doesn‘ t kümmern sich um diese Dinge und deshalb hört es auf zu arbeiten.
