ios - 我可以使用 Document Provider 扩展上的导航 Controller 来模拟文件夹导航吗？

我正在为我的应用程序实现一个文档提供程序，我必须在其中模拟文件夹导航。

Apple documentation说:

In either case, the host app presents a document picker view controller. The system then imbeds your Document Picker View Controller extension inside the app’s view controller. The app’s view controller provides a navigation bar with the document provider’s name, a location switcher, and a Done button. Your extension must provide the rest of the user interface.

还有:

The UIDocumentPickerExtensionViewController object acts as the root view controller for your user interface; therefore, it is often convenient to make it a container controller. You can then create a separate child view controllers for each mode, and your extension simply presents the appropriate child view controller in your prepareForPresentationInMode: method.

有没有办法使用主导航 Controller 来推送自定义 View Controller 并模拟 iCloud Document Provider 扩展的相同行为？

Best Answer-推荐答案

你不能，如果你放上你的导航 Controller ，你会看到两个导航栏——你的和系统的。系统导航栏是私有(private)的，您无权访问它。目前，您无法制作像 iCloud 这样的文档提供程序扩展。
