    <p>You might want to use the AVAudioPlayer instead of AudioServices.</p> <p>The following code will take an audio file (.m4a) and play the audio file 1 time. Don't forget to release "audioPlayer" when you're done with it.</p> <pre><code>NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"filename" ofType:@"m4a"]; NSURL *url = [NSURL fileURLWithPath:urlAddress]; NSError *error; AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&amp;error]; audioPlayer.numberOfLoops = 0; if (audioPlayer == nil) { NSLog([error description]); } else { [audioPlayer play]; } </code></pre> <p>Hope this example helps you with playing audio on the actual device. It might also be a good idea to increase the device audio when the file is playing.</p> <p>Note: You will need to add the AVFoundation framework to your project if you have not already done so. As well as import the header file.</p> <p><code>#import &lt;AVFoundation/AVFoundation.h&gt;</code> </p> <p><strong>Update:</strong></p> <p>From Apple's Core Audio Overview <a href="http://developer.apple.com/iphone/library/documentation/MusicAudio/Conceptual/CoreAudioOverview/WhatsinCoreAudio/WhatsinCoreAudio.html" rel="nofollow noreferrer">Document</a></p> <p><strong>Audio Session Services</strong></p> <p>Audio Session Services lets you manage audio sessions in your application—coordinating the audio behavior in your application with background applications on an iPhone or iPod touch. Audio Session Services consists of a subset of the functions, data types, and constants declared in the AudioServices.h header file in AudioToolbox.framework.</p> <p><strong>The AVAudioPlayer Class</strong></p> <p>The AVAudioPlayer class provides a simple Objective-C interface for playing sounds. If your application does not require stereo positioning or precise synchronization, and if you are not playing audio captured from a network stream, Apple recommends that you use this class for playback. This class is declared in the AVAudioPlayer.h header file in AVFoundation.framework.</p>

    1. COThanks. I will try it. Why would AudioServices fail to play sounds? Or, why use one over the other?

    2. COI'm using AVAudioPlayer now on a user event basis (i.e. button click). I release if not nil, create the instance, and play. Seems as though there is a small delay since I'm creating an instance each time. Is there a more efficient way?

    3. CO@user230949: You can make a sound object, similar to [this wrapper for `SystemSoundID`](http://stackoverflow.com/a/9802540/1431728), only you're making a wrapper for `AVAudioPlayer`.

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.
