copied!<p>Thanks to the comment above, and the failure of all my other ideas, I went ahead and took advantage of <strong>ARC</strong>.</p> <p>I didn't want to refactor my entire project to start using <strong>ARC</strong>, so I rewrote a new class to handle all of my audio needs and set some compiler flags (<strong>-fobjc-arc</strong>) to enable <strong>ARC</strong> just for that file.</p> <p>Not exactly sure what I was doing wrong before, but the system seems to be much better at managing memory than I am, and I'm happy to let it solve all my problems.</p> <p><strong>EDIT 2</strong>:</p> <p>Apparently Apple did finally fix their memory leak so I went back to my <strong>ARC</strong> solution which works fine for both <strong>iOS 5</strong> and <strong>iOS 6</strong>.</p> <p><strong>EDIT</strong>:</p> <p>I may have been a little premature.</p> <p>While implementing <strong>ARC</strong> for this was helpful in general, this specific problem goes deeper.</p> <p>Apparently, there is a leak in <strong>Core Foundation</strong> for <strong>iOS 6</strong>.</p> <p><a href="https://stackoverflow.com/questions/12498015/leak-from-nsurl-and-avaudioplayer-using-arc">Leak from NSURL and AVAudioPlayer using ARC</a></p> <p><a href="https://stackoverflow.com/questions/13309745/memory-leak-nsstring-nsurl">Memory Leak - NSString & NSURL</a></p> <p>Using <strong>ARC</strong>, it works fine on my <strong>Gen 3 iOS 5</strong> device, but leaks significantly for <strong>Gen 4/5 iOS 6</strong>.</p> <p>Without <strong>ARC</strong>, <strong>Gen 4/5 iOS 6</strong> works fine, but <strong>Gen 3 iOS 5</strong> crashes.</p> <p>I ended up making two versions of my new class, one using <strong>ARC</strong> and one not, and checking the system version at runtime <strong>[[UIDevice currentDevice] systemVersion]</strong> to determine which version to use.</p> <p>It may be a little clumsy, but does allow me to support the <strong>Gen 3</strong> devices. If <strong>Apple</strong> ever fixes their problem I can return to a single version at that time.</p>
