是否需要AudioServicesDisposeSystemSoundID? [英] Is AudioServicesDisposeSystemSoundID required?

问题描述

我最近开始使用AudioToolbox框架，并注意到有一个名为AudioServicesDisposeSystemSoundID()的方法.

I recently started working with the AudioToolbox framework and noticed that there is a method called AudioServicesDisposeSystemSoundID().

只知道，调用AudioServicesCreateSystemSoundID()初始化我的SystemSoundID时不调用上述方法是否会导致内存泄漏?我这样称呼它:

Just to know, is it a memory leak not to call the above method when calling AudioServicesCreateSystemSoundID() to init my SystemSoundID? I am calling it like:

AudioServicesCreateSystemSoundID((CFURLRef)filePath, &sound);

那样，filePath是一个NSURL和声音SystemSoundID.

That way filePath being a NSURL and sound SystemSoundID.

推荐答案

是. sound完成后调用它.否则，您可能会泄漏与sound相关联的所有内存(这对A/V文件可能很重要).

Yes. Call it when you're done with sound. Otherwise, you may leak any memory associated with sound (which can be significant for A/V files.)
