Questions tagged [uidocument]

UIDocument represents a user-editable document in an iOS application. It is an abstract base class in the UIKit framework. When it is used, its subclass takes the role of the model of a model-view-controller application. Because it implements the NSFilePresenter protocol, it significantly simplifies writing a document-based iOS application. Its Mac OS counterpart is NSDocument.
