    <p>I am trying to setup CoreData in a new project, but somehow am stuck locating the momd directory.</p> <p>I found several stackoverflow posts with similar questions, but was unable to solve the problem with the supplied answers. So here it is: What causes the first line to return 'nil' and the second one actually finds the momd directory?</p> <pre><code>NSURL *modelURL = [NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource:@"Project" ofType:@"momd"] ]; NSURL *modelURL = [NSURL fileURLWithPath: @"/Users/name/Library/Developer/Xcode/DerivedData/Project-afusjhpzsjyjdbesttxposfzlzrj/Build/Products/Debug/Project.app/Contents/MacOS/Project.momd" ]; </code></pre> <p>Edit: As Metabble commented, It's now logical that the mainbundle is unable to locate resources outside the Resources folder.</p> <p>But my problem still exists. I found out some more: I am using mogenerator to generate classes. (I used these instructions: <a href="http://www.esenciadev.com/2011/05/mogen-and-xcode4-integration/" rel="nofollow">http://www.esenciadev.com/2011/05/mogen-and-xcode4-integration/</a>). A script is called by a build rule process 'Data model version files'. In that build rule I've set the output to '${DERIVED_FILES_DIR}/${INPUT_FILE_BASE}.momd' but it looks like that is not the correct destination for the momd:</p> <pre><code>error: Could not create bundle folder for versioned model at '/Users/user/Library/Developer/Xcode/DerivedData/Project-afusjhpzsjyjdbesttxposfzlzrj/Build/Products/Debug/Project.app/Contents/MacOS/Project.momd' </code></pre> <p>If I delete the build rule, the code can find the momd. But that disables mogenerator...</p> <p>Anybody know what output files I need to set in the build rule?</p>

    1. COWhat do you see if you use `NSLog(@"Path: %@", [[NSBundle mainBundle] pathForResource:@"Project" ofType:@"momd"]);`?

    3. COOK, how about `NSLog(@"Path: %@", [[NSBundle mainBundle] resourcePath]);`? (I suspect it's looking in a "Resources" sub-folder, but I'd rather have it tell you than guess.)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
