    <p>If I understand correctly, you'd like a way of showing a 'no data to display' message if there are no results, and then replace that when data is available.</p> <p>My approach is generally to display a loading indicator (overlaid over the table view) to the user when I start loading the content (i.e. when first making the call to the server). You can have a flag on your controller that tracks whether you're currently loading data - set this to YES when you start loading, and then NO when loading completes. While loading, you can simply not display any cells in your table (assuming you have some other display to show the user that it's loading). E.g.</p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (isLoading) return 0; //Don't display any cells while loading if (modelArray.count == 0) return 1; //1 row for the cell indicating there's no data return modelArray.count; //1 row for each entry in array } </code></pre> <p>When the server returns data, remove the loading indicator and refresh the table view data.</p> <p>When no data is returned, presumably your model array will be empty. Simply check for this case in the <code>tableView:cellForRowAtIndexPath:</code> in your UITableViewDataSource, and if the array is empty, return a cell with a message indicating that there's no data, e.g.</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { if (modelArray.count == 0) { return noResultsMessageCell; } else { &lt;normal cell dequeueing code&gt; } } </code></pre>

    1. COI was thinking about doing something like this. First, I would prefer not to have a cell that says something like "no results" while the data is being downloaded. But it's annoyingly difficult to get this. Second, and more importantly, once you create the cell that says no more data do you have to get rid of that cell?

    2. COI've updated my answer - basically you conditionally return either the no results cell or the normal list of cells, but not both. You can control how many appear with `tableView:numberOfRowsInSection:`

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.
