Hi all,
I have a question about reading and writing file types. I have been
following an old Apple text editor example (http://developer.apple.com/documentation/Cocoa/Conceptual/TextArchitecture/Tasks/TextEditor.html
), and want to extend it to allow me to read and write rtf files. At
least, I want it to be able to round-trip rich text files with
TextEdit. From the example:
"At this stage of its development, your editor opens and saves
documents only with an extension of ????. To enable your application
to save and open documents with a recognized file type, you need to
use Xcode to configure the application’s document types settings as
described in “Storing Document Types Information in the Application's
Property List” in Document-Based Applications Overview. For complete
details about application property lists, see Runtime Configuration
Guidelines."
I read the documents, and an example from 2001 by Mike Beam () and
also looked at the settings for the TextEdit example. I ended up
setting it like so:
Creator: ttxt
Name: DocumentType
Extensions: rtfd
MIME Types: text/rtfd
OS Types: rtfd
My program writes files with rich content and reads them OK. But it
won't read rtfd files that I have created elsewhere (I can select such
files but they just don't open - nothing happens). Also, TextEdit will
read files that I have created using my editor, but they are in plain
text with lots of tutti-frutti.
Can anyone point me to an example that describes how I am supposed to
tell my application that it should read and write rtf (or rtfd) files?
Ian.
