How do I access the detail data (master detail relationship) from a fetch request in a core data document?

Question

Hello,

I am very new at using Xcode and I have worked my way through most of the code necessary for my program. I have a fetch request that is returning this:

2010-10-04 15:48:01.341 lzshow7.2[7001:10b] 004 Commando March
2010-10-04 15:48:01.352 lzshow7.2[7001:10b] <NSManagedObject: 0x29e370> (entity: Song; id: 0x2ab990 <x-coredata://CF5A85CE-BE0F-4ADC-979A-7F4214A8FB19/Song/p5> ; data: <fault>)
2010-10-04 15:48:01.409 lzshow7.2[7001:10b] 005 Polacca from Second Conccerto for Clarinet
2010-10-04 15:48:01.419 lzshow7.2[7001:10b] <NSManagedObject: 0x2c5a30> (entity: Song; id: 0x2ab170 <x-coredata://CF5A85CE-BE0F-4ADC-979A-7F4214A8FB19/Song/p14> ; data: {
    cueName = "Mars from The Planets";
    cueNo = 006;
    cueNotes = <040b7479 70656473 74726561 6d8103e8 84014084 8484124e 53417474 72696275 74656453 7472696e 67008484 084e534f 626a>;
    songToInstrument = "<relationship fault: 0x2ab750 'songToInstrument'>";
})

The first logged item "004 Commando March" has no detail information. The second Item "005 Polacca from Second Conccerto for Clarinet" does.

I'm not sure how to pull the detail information into a string. Additionally I'm not sure how to translate the "cueNotes" (a binary store type) to a string.

As always any help would be greatly appreciated!

Thank you,

Loren Zimmer
