如何使用segue为Facebook iOS Friend Picker设置自定义背景和单元格？

Question

我正在使用Facebook的SDK来向用户朋友展示。 但是当我调用segue时，我不知道如何更改表格的白色背景：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([segue.identifier isEqualToString:@"SegueToFriendPicker"]) {

        FBFriendPickerViewController *friendPickerController = (FBFriendPickerViewController *) segue.destinationViewController;
        friendPickerController.title = @"Pick Friends";
        friendPickerController.doneButton = nil;
        friendPickerController.allowsMultipleSelection = NO;
        friendPickerController.delegate = self;
        [friendPickerController loadData];

    }
}

来自FBFriendPickerViewController文档：

When the FBFriendPickerViewController view loads it creates a UITableView
object where the friends will be displayed. You can access this view through
the tableView property.

这可能有效：

friendPickerController.tableView.backgroundColor = /*YOUR COLOUR HERE*/;
