I've been working on a core data program for a while now. I'm trying to combine attributes of an entity in a text view for saving to PDF and Printing. One of the attributes of the entity uses binary data.
When I execute this:
NSData *myData = [object valueForKey:@"cueNotes"];
...it returns this:
typedstreamè@
NSMutableDataNSDataNSObjecti[276c]{\rtf1\ansi\ansicpg1252\cocoartf949\cocoasubrtf540
{\fonttbl\f0\fnil\fcharset0 LucidaGrande;}
{\colortbl;\red255\green255\blue255;}
\pard\tx560\tx1120\tx1680\tx2240\tx2800\tx3360\tx3920\tx4480\tx5040\tx5600\tx6160\tx6720\ql\qnatural\pardirnatural
\f0\fs20 \cf0 step one text}
when I try this:
NSAttributedString* myDataTry = [[[NSAttributedString alloc] initWithRTF:myData documentAttributes:nil] autorelease];
... myDataTry is nil. I read a little about the rtf format and then removed this:
typedstreamè@
NSMutableDataNSDataNSObjecti[276c]
...from the myData data but still get a nil result. Does anyone have any idea what I'm doing wrong?
Update: After thinking about the first answer I tried this (as well as a couple permutations):
NSString* notesString = [[[NSString alloc] initWithRTF:[object valueForKey:@"cueNotes"] documentAttributes:nil] autorelease];
as well as an allocated string and still no results.
Here is the results of the entity that I'm pulling from:
