presentFeedDialogModallywithSession不會發布消息給朋友

Question

Iam使用以下代碼在我朋友的Facebook牆上發佈消息。此代碼將消息發佈到登錄用戶牆上，但不發送給朋友的牆

Iam也給予「to」值，即朋友的facebook標識（116623456）和App_id，但同樣的問題仍然存在。

請提供一個很好的方向。

- (void)facebookViewControllerDoneWasPressed:(id)sender 
{ 
     NSLog(@"DonePressed Called"); 
     NSString* fid; 
     NSString* fbUserName; 

     NSString *message = [NSString stringWithFormat:@"You have been selected as a  health coach(Multiple Users1), You will be receiving daily and weekly reports from here on!!!!"]; 


     NSLog(@"Before For"); 

// NSString *SelectedFriends = nil; 
for (id<FBGraphUser> user in _friendPickerController.selection) 
{ 

    fid = user.id; 
    fbUserName = user.name; 


    NSLog(@"User Name =%@, USer id =%@",fbUserName, fid); 


} 
NSLog(@"After For"); 
NSLog(@"%@",fid); 

NSMutableDictionary *params = 
[NSMutableDictionary dictionaryWithObjectsAndKeys: 
@"4444444444444444",@"app_id", 
fid,@"to", 
nil]; 
// Invoke the dialog 


[FBWebDialogs presentFeedDialogModallyWithSession:nil 
             parameters:params 
              handler: 
^(FBWebDialogResult result, NSURL *resultURL, NSError *error) { 
    if (error) { 
     // Error launching the dialog or publishing a story. 
     NSLog(@"Error publishing story."); 
    } else { 
     if (result == FBWebDialogResultDialogNotCompleted) { 
      // User clicked the "x" icon 
      NSLog(@"User canceled story publishing."); 
     } else { 
      // Handle the publish feed callback 
      NSDictionary *urlParams = [self parseURLParams:[resultURL query]]; 
      if (![urlParams valueForKey:@"post_id"]) { 
       // User clicked the Cancel button 
       NSLog(@"User canceled story publishing."); 
      } else { 
       // User clicked the Share button 
       // Show the result in an alert 
       [[[UIAlertView alloc] initWithTitle:@"Result" 
              message:@"Message Posted Successfully" 
              delegate:self 
            cancelButtonTitle:@"OK!" 
            otherButtonTitles:nil] 
        show]; 


      } 
     } 
    } 
}];

- (void)facebookViewControllerDoneWasPressed:(id)sender { 
    NSMutableString *text = [[NSMutableString alloc] init]; 

    // 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 
    for (id<FBGraphUser> user in self.friendPickerController.selection) { 
     if ([text length]) { 
      [text appendString:@", "]; 
     } 
     [text appendString:user.name]; 

     NSString *fid=user.id; 
     NSString *fbUserName=user.name; 

     NSLog(@""); 

     NSMutableDictionary* params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Test miLineup!", @"message", @"Iphone Apps", @"name", nil]; 

     NSLog(@"\nparams=%@\n", params); 

     //Post to friend's wall. 
     [FBRequestConnection startWithGraphPath:[NSString stringWithFormat:@"%@/feed", fid] parameters:params HTTPMethod:@"POST" 
           completionHandler:^(FBRequestConnection *connection, id result, NSError *error) 
     { 
      //Tell the user that it worked. 
      UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Shared" 
                   message:[NSString stringWithFormat:@"Invited %@! error=%@", fbUserName, error] 
                   delegate:nil 
                 cancelButtonTitle:@"OK" 
                 otherButtonTitles:nil]; 
      [alertView show]; 
     } 
     ]; 

     //Close the friend picker. 
     //[self dismissModalViewControllerAnimated:YES];
