Instance Property


The document object associated with the main window.


@property(readonly, strong) __kindof NSDocument *currentDocument;


The value of this property is nil if it is called when the app is not active. This can occur during processing of a drag-and-drop operation, for example, in an implementation of readSelectionFromPasteboard:. In such a case, send the following message instead from an NSView subclass associated with the document:

[[[self window] windowController] document];
