我有一个正在开发的应用程序，其中包含表格视图中的用户时间线。这将是每个应用程序中相同的用户时间线。我已经对此进行了编码，并且效果很好。我的问题是，当我在调用中将 API 版本从 1 更改为 1.1 时，它停止工作。所有推文都将通过推文表进行，因此我不需要身份验证。除了在调用中更改 API 版本之外，我是否需要添加代码，或者设置授权只是为了使用新 API 显示时间线？除了简单地显示单个用户时间线并使用推文表来响应之外，我没有添加任何功能。我附上了我的代码。任何帮助都会很棒。谢谢你。

这就是我最终想出的。它对我需要它做的事情来说很好。希望它也可以帮助其他人。

我还添加了一个简单的加载器和可达性。如果您不需要它，只需删除底部的 NSNotification。

并确保添加

账户和社会框架

并将它们的头文件导入到您使用它的 .m 文件中。

祝你好运！
