    <p>I just downloaded your project &amp; found this section of code in <code>didSelectRowAtIndexPath</code> delegate where <code>reloadRowsAtIndexPaths</code> is used. </p> <pre><code>[tableView reloadRowsAtIndexPaths:indicesToReload withRowAnimation:UITableViewRowAnimationAutomatic]; [tableView beginUpdates]; [tableView endUpdates]; </code></pre> <p>instead of the above why don't you try this?</p> <pre><code>[tableView beginUpdates]; [tableView reloadRowsAtIndexPaths:indicesToReload withRowAnimation:UITableViewRowAnimationAutomatic]; [tableView endUpdates]; </code></pre> <p>The reason i am suggesting this is that I believe <code>reloadRowsAtIndexPaths:...</code> only works when wrapped inbetween calls to:</p> <pre><code>- (void)beginUpdates; - (void)endUpdates; </code></pre> <p>Outside of that, behavior is undefined and as you've discovered, fairly unreliable. Quoting relevant part of "<a href="http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/TableView_iPhone/AboutTableViewsiPhone/AboutTableViewsiPhone.html" rel="nofollow">Table View Programming Guide for iPhone OS</a>":</p> <blockquote> <p>To animate a batch insertion and deletion of rows and sections, call the insertion and deletion methods within an animation block defined by successive calls to beginUpdates and endUpdates. If you don’t call the insertion and deletion methods within this block, row and section indexes may be invalid. beginUpdates...endUpdates blocks are not nestable.</p> <p>At the conclusion of a block—that is, after endUpdates returns—the table view queries its data source and delegate as usual for row and section data. Thus the collection objects backing the table view should be updated to reflect the new or removed rows or sections.</p> <p>The reloadSections:withRowAnimation: and reloadRowsAtIndexPaths:withRowAnimation: methods, which were introduced in iPhone OS 3.0, are related to the methods discussed above. They allow you to request the table view to reload the data for specific sections and rows instead of loading the entire visible table view by calling reloadData.</p> </blockquote> <p>There could be other valid reason but let me mull on this a bit, since i have your code too I could muck around with it. Hopefully we should figure it out...</p>

    1. COIf you place beginUpdates before reloadRowsAtIndexPaths the cells immediately disappear when tapped. Placing it after reloadRowsAtIndexPaths works. Try out the test project and see what happens. Regarding the Apple docs, "To animate a batch insertion and deletion of rows and sections..." I'm not inserting or deleting rows or sections, I'm simply changing the height of cells, nothing more. I'm using reload so it knows to check their height since it changed. ;)

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.
