私は次のようにユーザーの壁に画像を投稿することができます：-

if (appDelegate.session.isOpen)
    {
        FBSession.activeSession  = appDelegate.session;            
        [FBRequestConnection startForUploadPhoto:img 
                               completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                                   [self showAlert:@"eCard Posted" result:result error:error];
                               }];

    }

ここでの要件は、友達ピッカークラスから友達を選び、選択した友達のウォール/タイムラインに画像を投稿することです。

私は次のようにフレンズピッカークラスを統合しました：-

if (appDelegate.session.isOpen)
    {
         FBSession.activeSession  = appDelegate.session; 
        if (self.friendPickerController == nil) {
            // Create friend picker, and get data loaded into it.
            self.friendPickerController = [[FBFriendPickerViewController alloc] init];
            self.friendPickerController.title = @"Pick Friends";
            self.friendPickerController.delegate = self;
        }

        [self.friendPickerController loadData];
        [self.friendPickerController clearSelection];            
        [self presentModalViewController:self.friendPickerController animated:YES];


   }

今デリゲートメソッドで：-

- (void)facebookViewControllerDoneWasPressed:(id)sender {

// we pick up the users from the selection, and create a string that we use to update the text view
// at the bottom of the display; note that self.selection is a property inherited from our base class
//UIImage *img = self.image;
    FBSession.activeSession = appDelegate.session;

for (id<FBGraphUser> user in self.friendPickerController.selection) {   

    FBSession.activeSession  = appDelegate.session; 
    if (appDelegate.session.isOpen)
    {            
        NSMutableDictionary  *postVariablesDictionary = [[NSMutableDictionary alloc] init];
       // [postVariablesDictionary setObject:@"me" forKey:@"name"]; 
       // [postVariablesDictionary setObject:self.image forKey:@"picture"];
        [postVariablesDictionary setObject:@"Sample Text" forKey:@"message"];
         NSLog(@"%@",user.id);
        [FBRequestConnection startForPostWithGraphPath:[NSString stringWithFormat:@"%@/feed",user.id] graphObject:[NSDictionary dictionaryWithDictionary:postVariablesDictionary] completionHandler:nil];


     }    
    else 
    {
        if (appDelegate.session.state != FBSessionStateCreated) {
            // Create a new, logged out session.
            appDelegate.session = [[FBSession alloc] init];
        }            
        // if the session isn't open, let's open it now and present the login UX to the user
        [appDelegate.session openWithCompletionHandler:^(FBSession *session, 
                                                         FBSessionState status, 
                                                         NSError *error) {
        }];
    } 

}

[self dismissModalViewControllerAnimated:YES];

}

上記のデリゲートメソッドは、常にエラーコード= 5facebooksdkエラーにつながります。上記の画像を選択した友達のウォールに投稿するには、どのAPIを呼び出す必要がありますか。

私を助けてください.......

最後に、友達の壁に画像を投稿できるようになりました。

次のように変更されたデリゲートメソッド:--

if (appDelegate.session.isOpen)

            }];
        } 

    }

}
[self dismissModalViewControllerAnimated:YES];

}
