Title Body

I'm trying to upload a photo to a Facebook page I own using the iOS SDK and graph API. I've been able to upload photos to my own wall. I've also been able to post a message to my fan page wall as an admin and create an album on my fan page, so I think I'm making the right calls, but not succeeding. This is what I'm currently doing. I'm logging in using Facebook *fb = [[Facebook alloc] init]; self.facebook = fb; [fb release]; NSArray *permissions = [[NSArray arrayWithObjects:@"read_stream", @"offline_access", @"publish_stream", @"manage_pages", @"user_photos", @"friends_photos",nil] retain]; [facebook authorize:FB_APP_ID permissions:permissions delegate:self]; [permissions release]; After I log in, I request the accounts [facebook requestWithGraphPath:@"/me/accounts" andDelegate:self]; The accounts are returned to me with access tokens for each page and app I own. I use a simple loop to parse through the accounts to extra the access_token supplied for the page I wish to upload a photo to. I then set my access token of my facebook object to the new access_token. facebook.accessToken = new_accessToken; and try and upload a photo my fan page using UIImage *uploadImage = [UIImage imageNamed:@"t200.jpg"]; NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys: uploadImage, @"source", @"test caption", @"message", nil]; [facebook requestWithGraphPath:@"/me/photos" andParams:params andHttpMethod:@"POST" andDelegate:self]; The response I receive is {"error":{"type":"OAuthException","message":"(#1) An unknown error occurred"}} Is this a bug in the facebook graph API? I also tried making this call using standard HTTPS requests, and get the same result.
