Ich versuche, einige Inapp-Kauf zu implementieren. Ich habe das Online-Tutorial verfolgt und mein Code ist unten veröffentlicht. Ich habe die In-App-Käufe zu meinem iTunes Connect-Konto hinzugefügt, aber wenn ich den Code ausführe, ruft er die "didfailwitterror" -Methode auf, die die Liste der Produkte nicht laden kann. Hat jemand anderes dieses Problem und kennt möglicherweise eine Lösung?In-App-Kauf fehlgeschlagen, Liste der Produkte zu laden

Ich denke, es kein Code Problem ist, dass Sie ungültige Kennung bekommen, weil Sie nicht ein paar Schritte i einige Bedingungen erwähnen Abschluss bitte diese – morroko
