    <p>I'm trying to come up with a way that I can pre-load data into core data while using an <code>UIManagedDocument</code>. My attempt so far is to make the document in a "Loader" app using this code.. </p> <pre><code>NSURL *url = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]; url = [url URLByAppendingPathComponent:@"Default Database"]; if(![[NSFileManager defaultManager] fileExistsAtPath:[self.document.fileURL path]]){ [self.document saveToURL:self.document.fileURL forSaveOperation:UIDocumentSaveForCreating completionHandler:^(BOOL success){ if(success)[self loadDataIntoDocument]; }]; } </code></pre> <p>and then copy the persistentStore file from the 'documents' directory that is created in the simulator's directory to the resources section in Xcode for the main app that will be using the loaded database.</p> <p>My problem is that I can't figure out how to copy that document from the app bundle and use it as a document successfully. </p> <p>I've tried copying the document directory as-is from the app bundle and trying to access it as a document which gave the error that <code>UIManagedDocument</code> can only access a package of files. I've tried creating another fresh document in the main app and copying the persistentStore from the bundle over the one that is created in the document with the same error. And I've tried using <code>UIManagedDocument</code>'s <code>-(BOOL)loadFromContents:ofType:error:</code> method .. I'm not even sure this is what I should be using.</p> <p>Does anyone have an idea as to how this is normally done? Thanks! </p>

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.
