NSTextStorage

NSTextStorage

Mac OS X 10.0

This subclass of NSMutableAttributedString is the data model for Cocoa's text-handling system. NSTextStorage manages one or more NSLayoutManagers, which are responsible for determining how the text should be displayed. Two additional classes have an equally important role in the text-handling system, as does NSTextStorage: NSTextContainer and NSTextView. In terms of the Model-View-Controller pattern, NSTextStorage is the model, NSTextView is the view, and NSLayoutManager and NSTextContainer serve as controllers between the data layer and the view layer.
