Type Property


Returns whether the document object stores its contents in the user's iCloud document storage.


@property(class, readonly) BOOL usesUbiquitousStorage;


This method’s default implementation returns YES if your app has a valid iCloud document storage entitlement (com.apple.developer.ubiquity-container-identifiers or com.apple.developer.icloud-container-identifiers, as described in Entitlement Key Reference). When this method returns YES, the system adds new menu items and other UI for iCloud documents, as appropriate, and allows documents to be saved or moved into the primary iCloud container. (The primary iCloud container is the one identified by the first container identifier string in the iCloud Containers list in the Xcode target editor.)

To indicate that your NSDocument subclass does not use iCloud storage, override this method to return NO.
