    <p>If you are referring to the tile view, you can duplicate that using a <code>UITableView</code> or a <code>UIScrollView</code>. If you want it to side scroll then a <code>UIScrollView</code> is the starting point.</p> <p>If you want it to scroll vertically (which I recommend on iPhone) then use a <code>UITableView</code> with a custom <code>UITableViewCell</code>. </p> <p>As for the Core Data side, you are probably coming at this incorrect, you are trying to store UI state information (how many photos are in a cell) in core data. Core Data should not care about how many images are in a cell.</p> <h2>UITableViewCell</h2> <p>To use a <code>UITableView</code> you would create an array that contains all of your images. You can then determine how many rows you need by dividing that array by the number of images per row. </p> <p>From there you should subclass <code>UITableViewCell</code> and pass in the 4 images for that cell to draw. Then it is a simple matter of adding 4 <code>UIImageView</code> instances to the custom cell and setting the images. </p> <h2>UIScrollView</h2> <p>For a scrollview you crate a <code>UIImageView</code> for each image and then add them as subviews of the <code>UIScrollView</code>. You would then set the frame of each <code>UIImageView</code> so that they are displayed in a grid. </p> <p>If you find you have more images than you can hold in memory at once then you will need to deal with tiling, effectively paying attention to where the user is scrolling and filling in (via moving the offscreen image views) ahead of the edge the user is scrolling towards. This is the same thing you get effectively for free with a <code>UITableView</code> via its queuing of cells.</p>

    1. COThanks for the tips, like I mentioned to @sosborn I was wondering if there was any way to use NSFetchedResultsController's didChangeObject:atIndexPath: so I won't have to reset and reload the entire table each time there is a change. In any case, I think I'll go with this for now. Thanks again.

    2. COYes you can but it requires calculating the indexPath offset and then reacting to it properly. Can be a lot of work, especially with inserts and deletes but it can be done with a UITableView. In a scrollView design I would build my own context watcher instead.

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.
