Declaration

Parameters

  • url:

Discussion

You can override this method to customize the reopening of autosaved documents.

This method is invoked by the NSDocumentController method makeDocument(withContentsOf:ofType:). The default implementation of this method calls the init() and read(from:ofType:) methods and sets values for the fileURL, fileType, and fileModificationDate properties.

For backward binary compatibility with OS X v10.3 and earlier, the default implementation of this method instead invokes initWithContentsOfFile:ofType: if it is overridden and the URL uses the file: scheme. It still updates the fileModificationDate property in this situation.
