    <p>I am trying for the past few days to upload a locally saved sounde record to a server (which handels it with a php file and saves it to the server). the problem is that I can't find a way to do that.</p> <p>While recording the sound (AVAudioRecorder) it saves at a "NSTemporaryDirectory()":</p> <pre><code>NSURL *temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]]; </code></pre> <p>Now, everywhere I checked the answer was to use <a href="http://allseeing-i.com/ASIHTTPRequest/" rel="nofollow">ASIHTTPRequest</a>. but the problem is that it is not supported in ios6.</p> <p>There are some other libraries for it but nothing works no matter what and how I try. I would love it if someone could help me...</p> <p><em>Here is my code:</em></p> <p><strong>ViewController.h</strong></p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import &lt;AVFoundation/AVFoundation.h&gt;

    2. COit is uploading the file. i have updated a `UILabel` named 'recStateLabel' with how many of how many was sent: `recStateLabel.text = [NSString stringWithFormat:@"Sent %lld/%lld", totalBytesWritten, totalBytesExpectedToWrite];` and it does nothing... i don't get response from the server and the file is not uploded to the directory. the PHP file works because the app on the Android works with it perfectly

    3. COOne thing is that you might be using AFNetworking wrong. Your supposed to subclass AFHttpCLient for every API, and you're always supposed to use a singleton.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
