    <p>UIWebView doesn't give you any progress information in the normal mode. What you need to do is first fetch your data asynchronously using an NSURLConnection. When the NSURLConnection delegate method <code>connection:didReceiveResponse</code>, you're going to take the number you get from <code>expectedContentLength</code> and use that as your max value. Then, inside the delegate method <code>connection:didReceiveData</code>, you're going to use the <code>length</code> property of the NSData instance to tell you how far along you are, so your progress fraction will be <code>length / maxLength</code> , normalized to between 0.0 and 1.0.</p> <p>Finally, you're going to init the webview with data instead of a URL (in your <code>connection:didFinishLoading</code> delegate method). </p> <p>Two caveats:</p> <ol> <li><p>It is possible that the <code>expectedContentLength</code> property of the NSURLResponse is going to be <strong>-1</strong> (<code>NSURLReponseUnknownLength</code> constant). In that case, I would suggest throwing up a standard UIActivityIndicator that you shut off inside <code>connection:didFinishLoading</code>.</p></li> <li><p>Make sure that any time you manipulate a visible control from one of the NSURLConnection delegate methods, you do so by calling <code>performSelectorOnMainThread:</code> - otherwise you'll start getting the dreaded EXC_BAD_ACCESS errors.</p></li> </ol> <p>Using this technique, you can show a progress bar when you know how much data you're supposed to get, and a spinner when you don't know.</p>

    1. COThe problem with implementing the NSURLConnection data fetch on top of the UIWebView load request is that you're grabbing the same data twice, which is wasteful on a lightweight connection. You can load the NSData instance directly into the UIWebView with `loadData:MIMEType:textEncodingName:baseURL:`, but this can compromise other facets of using UIWebView.

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).
