Declaration

- saveOperation:

The delegate to which the selector message is sent.
- didSaveSelector:
The selector of the message sent to the delegate.

Discussion
When saving is completed, regardless of success or failure, or has been canceled, sends the message selected by didSaveSelector to the delegate, with contextInfo as the last argument. The method selected by didSaveSelector must have the same signature as:
- (void)document:(NSDocument *)doc didSave:(BOOL)didSave contextInfo:(void *)contextInfoInvoked from save(withDelegate:didSave:contextInfo:), and from the saveAs(_:) and saveTo(_:) action methods. The default implementation of this method first makes sure that any editor registered using the Cocoa Bindings NSEditorRegistration informal protocol has committed its changes, then creates a Save panel, adds a standard file format accessory view (if there is more than one file type for the user to choose from and shouldRunSavePanelWithAccessoryView returns true), sets various attributes of the panel, invokes prepareSavePanel(_:) to provide an opportunity for customization, then presents the panel. If the user approves the panel, the default implementation sends the message save(to:ofType:for:delegate:didSave:contextInfo:).
For backward binary compatibility with Mac OS v10.3 and earlier, the default implementation of this method instead invokes the deprecated saveToFile:saveOperation:delegate:didSaveSelector:contextInfo: if it is overridden, even if the user cancels the panel.
