UIViewController作为一个单例 [英] UIViewController as a singleton

问题描述

我在选项卡栏应用程序中有一个UIViewController.我已经从MainWindow.nib文件中添加了控制器(即不是以编程方式).

I have a UIViewController in a tab bar application. I've added the controller from the MainWindow.nib file (i.e. not programatically).

我的问题是如何使我的视图控制器成为一个单例?(以解决Facebook委托问题).

My question is how can I make my view controller a singleton? (To resolve the Facebook delegate issue).

推荐答案

您可能希望使"Facebook连接代码"成为单例(或应用程序委托的一部分)，而不是视图控制器本身.然后，只需将FB事物与需要它的任何视图控制器连接起来即可.

You probably want to make your "Facebook connection code" a singleton (or part of the app delegate), but not the view controller itself. Then just wire up the FB thing with any view controller that needs it.
