    <p>I've recently posted a question about reducing the timeout of an FTP connection (<a href="https://stackoverflow.com/questions/19292936/ios-how-to-reduce-an-ftp-connection-timeout">click here to see it if you want</a>).</p> <p>Now, I've been asked to post a more specific question, focusing on the component we're using for the FTP download.</p> <p>We're using Nico Kreipke's FTPManager (<a href="https://github.com/nkreipke/FTPManager" rel="nofollow noreferrer">click here to go to its GitHub</a>).</p> <p>What we're trying to implement is to download data from an FTP address, and if it fails we'll fallback to use an HTTPS web server.</p> <p>When the FTP address we give isn't available, it takes about one minute to timeout.</p> <p>The question is, how can I reduce that timeout?</p> <p>Best regards,<br/> Tiago</p> <p><strong>Some More Info</strong></p> <p>I forgot to say, the FTP connection is done with an IP (local network).</p> <p><strong>Johan's Tip</strong></p> <p>I added a property to FTPManager, a <code>double</code> named <code>timeout</code>.</p> <p>Then I've overridden the accessor of <code>serverReadStream</code>, a property used throughout FTPManager to hold the read stream, so that it would configure the timeout interval for all requests.</p> <pre><code>- (NSInputStream *)serverReadStream { return _serverReadStream; } - (void)setServerReadStream:(NSInputStream *)serverReadStream { if ((_serverReadStream = serverReadStream)) { CFNumberRef number = CFNumberCreate(kCFAllocatorDefault, kCFNumberDoubleType, &amp;_timeout); CFReadStreamSetProperty((__bridge CFReadStreamRef)(_serverReadStream), _kCFStreamPropertyReadTimeout, number); CFRelease(number); } } </code></pre> <p><code>_kCFStreamPropertyReadTimeout</code> is defined by:</p> <pre><code>#define _kCFStreamPropertyReadTimeout CFSTR("_kCFStreamPropertyReadTimeout") </code></pre> <p>However, it still takes about one minute to timeout. I set the timeout before connecting to the FTP address, right after creating <code>ftpManager</code>. The code I use to set the timeout follows:</p> <pre><code>FTPManager *ftpManager = [[FTPManager alloc] init]; [ftpManager setTimeout:10]; </code></pre>

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.
