Instance Method

autosave(withDelegate:didAutosave:contextInfo:)

Autosaves the document’s contents at an appropriate location.

Declaration

func autosave(withDelegate delegate: Any?, didAutosave didAutosaveSelector: Selector?, contextInfo: UnsafeMutableRawPointer?)

Parameters

delegate

The delegate to which the selector message is sent.

didAutosaveSelector

The selector of the message sent to the delegate.

contextInfo

Object passed with the callback to provide any additional context information.

Discussion

After autosaving, sends the message selected by didAutosaveSelector to the delegate, with contextInfo as the last argument. The method selected by didAutosaveSelector must have the same signature as:

- (void)document:(NSDocument *)document didAutosave:(BOOL)didAutosaveSuccessfully contextInfo:(void *)contextInfo

If an error occurs while autosaving, the method reports it to the user before sending the delegate a succeeded:NO message.
