I've been programming in Cocoa for 12 months now so I may not understand the
subject fully but my NSTextView Data binding is connected to a Core Data
attribute of type "Binary Data" (NSData) and this works when I manually type in
text, set some attributes like underline or font, save it and reopen it.
Since I have 4,000 files to cycle through I want to do this all
programatically. To simplify things I tried to do this with an NSString
instead of an NSAttributableString. I wrote a test app that creates a new
document, pulls the entity "newNote" and uses the following code to set the
NSData object:
NSData *noteData = [s dataUsingEncoding:NSUnicodeStringEncoding];
[newNote setValue:noteData forKey:@"noteData"];
I then save the document and loop around again. This works fine with the
NSString. After the 4,000 are loaded in, if I open one of the documents in my
interface and look in the textView I see the string. I guess don't fully
understand how to repeat this process with an AttributedString. I don't see
how NSTextStorage applies in this scenario. Maybe I'm skipping a step.
