An NSSavePanel object creates and manages a Save panel and allows you to run the panel in a modal loop

An NSSavePanel object creates and manages a Save panel and allows you to run the panel in a modal loop. The Save panel provides a simple way for a user to specify a file to use when saving a document or other data. It can restrict the user to files of a certain type, as specified by an extension.

An NSSavePanel object manages a panel that allows users to specify the directory and name under which a file is saved. It supports browsing of the file system, and it accommodates custom accessory views.

An NSSavePanel object may have a delegate. The methods that delegates of NSSavePanel may implement are specified by the NSOpenSavePanelDelegate protocol.

In a sandboxed app, when a user saves a document, the Save dialog is presented by the powerbox, not AppKit. OS X then adds the saved file to the app’s sandbox (if necessary) to allow the app to write to the file.
