Question

我正试图在UITableView的应用中显示来自 Facebook 的朋友。但是，我TableView保持空白。以下是我提取UITableView。

的代码

-(IBAction)testfriends {
    FBFriendPickerViewController *friendPickerController = [[FBFriendPickerViewController alloc] init];
    friendPickerController.title = @"Pick Friends";
    [friendPickerController loadData];

    // Use the modal wrapper method to display the picker.
    [friendPickerController presentModallyFromViewController:self animated:YES handler:
     ^(FBViewController *innerSender, BOOL donePressed) {
         if (!donePressed) {
             return;
         }

         NSString *message;

         if (friendPickerController.selection.count == 0) {
             message = @"<No Friends Selected>";
         } else {

             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 friendPickerController.selection) {
                 if ([text length]) {
                     [text appendString:@", "];
                 }
                 [text appendString:user.name];
             }
             message = text;
         }

         [[[UIAlertView alloc] initWithTitle:@"You Picked:"
                                     message:message
                                    delegate:nil
                           cancelButtonTitle:@"OK"
                           otherButtonTitles:nil]
          show];
     }];
}

我在这里缺少什么？它直接来自Facebook Sample，但即使在示例应用程序中，也无法工作。
