ios - presentFeedDialogModallywithSession 不向朋友发布消息

Question

我正在使用以下代码在我朋友的 Facebook 墙上发布消息。此代码将消息发布到登录的用户墙，但不发布到朋友的墙

我还给出了“to”值，即朋友 facebook id (116623456) 和 App_id 但同样的问题仍然存在。

请提供一个好的方向。

- (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]

        //Close the friend picker.
