    <p>I have a basic implementation for iCarousel where I am pulling images from a core-data store. I am experiencing memory related crashes when you get a lot of images loaded, as I guess is expected. The problem is I don't know of any way to use the AsyncImageView library since there is no NSURL reverence for a core-data object. Anyone know another way to manage this memory issue?</p> <p>Here is my iCarousel viewForItemAtIndex</p> <pre><code>- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view { JournalEntry *journalEntry = (JournalEntry *)[fetchedResultsController objectAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0]]; if (view == nil) { view = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 240.0f, 240.0f)] autorelease]; view.contentMode = UIViewContentModeScaleAspectFit; } [((UIImageView *)view) setImage:[journalEntry.image valueForKey:@"image"]]; NSLog(@"%i", index); return view; } </code></pre> <p>For reference here is code for adding images to my core-data store straight out of the iPhoneCoreDataRecipes sample code.</p> <pre><code>@implementation ImageToDataTransformer + (BOOL)allowsReverseTransformation { return YES; } + (Class)transformedValueClass { return [NSData class]; } - (id)transformedValue:(id)value { NSData *data = UIImagePNGRepresentation(value); return data; } - (id)reverseTransformedValue:(id)value { UIImage *uiImage = [[UIImage alloc] initWithData:value]; return [uiImage autorelease]; } @end </code></pre>

    2. COUsing AsyncImageView wouldn't be hard, but depending on how you're dealing with Core Data it might not help. It would be useful to know (a) what the Core Data entity that stores the image looks like, and (b) what your code to provide those images to iCarousel looks like (probably your -carousel:viewForItemAtIndex:reusingView:, but really wherever you're getting images from your Core Data entity).

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.
