concurrency

I have a document based application. Saving the document can take a few seconds, so I want to enable the user to continue using the program while it saves the document in the background.

Due to the document architecture, my application is asked to save to a temporary location and that temporary file is then copied over the old file. However, this means that I can not just run my file saving code in the background and return way before it is done, since the temporary file has to be written completely before it can be copied.

Is there a way to disable this temporary-file-behavior or otherwise enable file saving in the background?

I think I may be missing the obvious but I'm not sure. The section on subclassing NSDocument in the docs states that subclasses of NSDocument must override one reading and one writing method. If I'm creating a viewer application that will not write anything back, do I still need to override a writing… >>> More
