AudioToolbox库AVAudioPlayer中的内存泄漏 [英] memory leak in AudioToolbox library AVAudioPlayer

问题描述

AVAudioPlayer对象是否存在存储导线问题?在模拟器中使用AVAudioPlayer时出现内存泄漏.我如何创建AVAudioPlayer都没有关系.我用过initWithContentsOfURL和InitWithData.下面是代码片段.完整项目@ Github https://github.com/docchang/MemoryLeakAVAudioPlayer

Is there a memory lead issue with the AVAudioPlayer object? I'm getting a memory leak when using AVAudioPlayer in the simulator. It doesn't matter how I created the AVAudioPlayer. I've used initWithContentsOfURL and InitWithData. Below is a snippet of the code. Full project @ Github https://github.com/docchang/MemoryLeakAVAudioPlayer

NSError *error;
NSURL *playerURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Bell" ofType:@"m4a"]];   
self.playerWithURL = [[AVAudioPlayer alloc] initWithContentsOfURL:playerURL error:&error];
if (!playerWithURL) {
    NSLog(@"no %@.%@: %@",@"Introduction2", @"m4a", [error localizedDescription]);  
}
playerWithURL.volume = 0.9f;
playerWithURL.numberOfLoops = 0;
[playerWithURL play];

但是在设备上进行测试时没有内存泄漏.这个问题开始倾向于AudioToolBox库的问题，但只想与stackoverflow人员确认即可.

However there is no memory leak when testing it on the device. This issue is starting to leaning towards issue with the AudioToolBox library, but just want to confirm it with stackoverflow folks.

推荐答案

使用AVAudioPlayer时遇到相同的内存泄漏.我在网络上看到过几篇关于AVAudioPlayer和VideoPlayer库发生类似泄漏的帖子.库本身(苹果怪)似乎是个问题:

I am getting the same memory leak when using AVAudioPlayer. I have seen a few posts about similar occurrences of this leak with the AVAudioPlayer and VideoPlayer libraries around the web. It appears to be a problem with the library itself (blame Apple):

1. iPhone:OpenAL& AudioToolbox泄漏
2. https://appcelerator.lighthouseapp.com/projects/32238/tickets/1992-ios-strange-behavior-and-intermittant-mem-leak-on-embedded-video-test-case a>

1. iPhone: OpenAL & AudioToolbox leak

当目标在设备上运行时，泄漏也消失了.

Also seeing the leak disappear when the target is run on the device.
