使用MPMoviePlayerViewController iOS 4.2时，AudioToolbox的iPhone内存泄漏 [英] iPhone Memory Leak from AudioToolbox when using MPMoviePlayerViewController iOS 4.2

问题描述

我正在使用以下代码（在标签栏应用程序中的视图控制器内）播放用户选择表格行后从主包中加载的视频。

I'm using the following code (inside a view controller in a tab bar application) to play video loaded from the main bundle after a user selects a table row.

- (void)loadMoviePlayer:(NSString*)moviePath
{
    NSURL* fileURL    =   [[NSURL alloc] initFileURLWithPath:moviePath];

    MPMoviePlayerViewController* player = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
    [fileURL release];

    [self presentMoviePlayerViewControllerAnimated:player];
    [player release];
}

该应用程序在模拟器中构建并运行时没有任何明显问题（我没有'尚未在设备上测试过）但是当我通过仪器运行时，在视频播放过程中会发生内存泄漏。
Instruments强调AudioToolbox为'Responsible Library'和 SimAggregateDevice :: SimAggregateDevice（_CFString const *，_CFString const *，long&）
和

The app builds and runs without any obvious problems in the simulator (I haven't tested on a device yet) but when I run it through Instruments a memory leak occurs during video playback. Instruments highlights the AudioToolbox as the 'Responsible Library' and SimAggregateDevice::SimAggregateDevice(_CFString const*, _CFString const*, long&) and

APComponent::CreateDispatchTable(AudioComponentPluginInterface*, unsigned long)

作为'负责任的框架'。

as the 'Responsible Frame(s)'.

您可以获得的任何亮点都将非常感谢！
谢谢。

Any light you can shed on this would be much appreciated! Thanks.

推荐答案

问题不在于模拟器本身，而是而是为Mac OS X编译的AVFoundation
框架。 - Alex Nichol 2011年8月17日23:53

The problem isn't the "simulator" itself, but rather the AVFoundation framework compiled for Mac OS X. – Alex Nichol Aug 17 '11 at 23:53
