    copied!<p>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. </p> <p>When I execute this: </p> <p><code>NSData *myData = [object valueForKey:@"cueNotes"];</code></p> <p>...it returns this:</p> <pre><code> 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} </code></pre> <p>when I try this: </p> <pre><code>NSAttributedString* myDataTry = [[[NSAttributedString alloc] initWithRTF:myData documentAttributes:nil] autorelease]; </code></pre> <p>... myDataTry is nil. I read a little about the rtf format and then removed this: </p> <pre><code>typedstreamè@ NSMutableDataNSDataNSObjecti[276c] </code></pre> <p>...from the myData data but still get a nil result. Does anyone have any idea what I'm doing wrong?</p> <p>Update: After thinking about the first answer I tried this (as well as a couple permutations):</p> <pre><code>NSString* notesString = [[[NSString alloc] initWithRTF:[object valueForKey:@"cueNotes"] documentAttributes:nil] autorelease]; </code></pre> <p>as well as an allocated string and still no results.</p> <p>Here is the results of the entity that I'm pulling from:</p> <pre><code>2010-10-30 00:47:32.867 lzshow7.2[4222:10b] &lt;NSManagedObject: 0x2a4850&gt; (entity: Song; id: 0x26a030 &lt;x-coredata:///Song/t172F066B-285C-4125-B2FA-CFFA6A353D102&gt; ; data: { cueName = Stupid; cueNo = 001; cueNotes = &lt;040b7479 70656473 74726561 6d8103e8 84014084 84840d4e 534d7574 61626c65 44617461 00848406 4e534461 74610084 8408&gt;; songToEffect = ( ); songToInstrument = ( ); </code></pre> <p>})</p>
