    <p>I would say something like this:</p> <pre><code>- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { self.resumePreviousSettingAfterEditing = true; [self.topImageView setImage:image]; [cubeModel setImage:image forFace:[cubeModel.validFaces objectAtIndex:selectedRowInFacePicker]]; [self dismissImagePickerAnimated:true]; </code></pre> <p>}</p> <p>You register an event in your controller to handle the image selection. In that event handler, call a method somewhere, say in your model to set the new image. That function would look something like this:</p> <pre><code> (void)saveImage:(UIImage *)image withName:(NSString *)imageName { // get the image path NSString *filename = [self determineImagePath:imageName]; // make sure the file is removed if it exists NSFileManager *fileManager = [NSFileManager defaultManager]; if([fileManager fileExistsAtPath:filename]) { if(NO == [fileManager removeItemAtPath:filename error:NULL]) { } } // Now, save the image to a file. if(NO == [UIImagePNGRepresentation(image) writeToFile:filename atomically:YES]) { [NSException raise:@"Image Save Failed" format:@"Unable to store image %s", filename]; } } </code></pre> <p>When you want to load the image again, you would so something like: </p> <pre><code>- (UIImage *)loadImage:(NSString *)imageName { NSString *filename = [self determineImagePath:imageName]; NSFileManager *fileManager = [NSFileManager defaultManager]; self.currentImage = nil; if([fileManager fileExistsAtPath:filename]) { NSData *imageData = [[NSData alloc] initWithContentsOfFile:filename]; UIImage *image = [UIImage imageWithData:imageData]; self.currentImage = image; } return self.currentImage; } </code></pre> <p>And don't get me started on transforming which is way harder than it should be.</p> <p>Enjoy, Jacob</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
