    <p>Pre-populating images to a SQLite database for use with Core Data turns out to be fairly trivial.</p> <ol> <li>First configure your Core Data application, implementing your attribute to contain images as a "Binary" type. Build the application and navigate to your view utilizing Core Data within the application simulator. This will initialize the SQLite database as required for use with Core Data (assuming you've implemeted the persistentStoreCoordinator as follows).</li> </ol> <pre><code>- (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (persistentStoreCoordinator != nil) { return persistentStoreCoordinator; } NSString *storePath = [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"YourDBName.sqlite"]; // Set up the store. // For the sake of illustration, provide a pre-populated default store. NSFileManager *fileManager = [NSFileManager defaultManager]; // If the expected store doesn’t exist, copy the default store. if (![fileManager fileExistsAtPath:storePath]) { NSString *defaultStorePath = [[NSBundle mainBundle] pathForResource:@"YourDBName" ofType:@"sqlite"]; if (defaultStorePath) { [fileManager copyItemAtPath:defaultStorePath toPath:storePath error:NULL]; } } NSURL *storeUrl = [NSURL fileURLWithPath:storePath]; NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]]; NSError *error; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { // Update to handle the error appropriately. NSLog(@"Unresolved error %@, %@", error, [error userInfo]); exit(-1); // Fail } return persistentStoreCoordinator; } </code></pre> <ol> <li><p>Navigate to the application data at "Users//Library/Application Support/iPhone Simulator/User/Applications/". If you sort the folder by "Date Modified," your application will have the latest date (assuming you haven't built any other applications in the mean time). Enter the application folder and the initialized &lt; YourDBName.sqlite > will reside in the Documents folder. Copy the SQLite database to another location (like your desktop) and delete the original file (this is necessary to allow Core Data to reload the pre-populated SQLite database you are about to create).</p></li> <li><p>Open &lt; YourDBName.sqlite > with your favorite SQLite editor (the SQLite Manager plugin for Firefox is an adequate, and free, option). Add entries to your table, inserting any images as a "BLOB."</p></li> <li><p>Within XCode add &lt; YourDBName.sqlite > as an existing file. Core Data will copy this file to the application data folder the next time you launch your application if it does not already exist there (you deleted the original right?).</p></li> <li><p>Access your pre-populated images within your code with <code>[UIImage imageWithData:&lt; DataObject >.&lt; ImageAttributeName ></code></p></li> </ol>

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.
