Dokumentierten Verfahren zur Verwendung mit Facebook für das iPhone zum Hochladen von Fotos

Question

Nachdem ich auf der Suche quer durch diesen Beitrag auf den Facebook-Foren kam:

Sie füttern die facebook UIImage-Objekt. Das scheint logisch, aber wo ist das dokumentiert? Die API-Dokumentation ist für alle Plattformen verallgemeinert. Wo sind die iPhone-spezifischen Anforderungen für Argumente und ihre Datentypen?

Dank

******-Update ***** Ich habe kam noch nicht über irgendwelche Dokumente API Cocoa gehört. Ich sammelte jedoch die Informationen, die ich benötigte, indem ich Foreninformationen, Facebook-Beispielcode und etwas Klebstoff zusammenstellte.

Hoffentlich werden sie in den nächsten Monaten etwas Konkreteres herausgeben.

Der Vollständigkeit halber:

Im Folgenden wird erläutert, wie mit Facebook Connect zu interagieren: https://developers.facebook.com/docs/guides/web/

Die API-Aufrufe: https://developers.facebook.com/docs/reference/api/

Joe Hewitt (der Autor der Facebook iPhone App) veröffentlichte große Teile der Facebook-Anwendung als sein Three20 Framework. Es ist auf github gehostet.
