点击 Twitter 和 Facebook 的 Tweet 或 Share 时出现的“文本框”。那些是什么做的？可以制作类似的东西吗？我正在尝试自定义它们，以便它将作为 tableView 的“评论”。我说的是这两个：
我试图让它说“评论”而不是“推文”和“Facebook”。然后是“完成”，上面写着“发送”和“发布”。知道如何/在哪里可以创建/自定义这些吗？

这些是私有视图控制器。你不能（好吧，不应该）自定义它们——你必须自己重新实现它们。
但是，您可以使用私有方法-recursiveDescription来了解视图层次结构的构造方式。创建一个简单的应用程序，使用UIActivityViewController. 展示它，选择 Twitter 或 Facebook，然后在调试器中暂停应用程序。在控制台中键入po [[[UIApplication sharedApplication] keyWindow] recursiveDescription]以列出当前视图层次结构。
编辑：好的，我很好奇……</p>

基本上，这就是您所期望的：一堆背景图像、一个标签和按钮来伪造导航栏样式和一个大文本视图的内容。
