录制音频剪辑时设置时间限制？

问题描述

我按照帖子标题查找了搜索字词，但是唉...

我正在使用AVFoundation构建iPhone应用程序。

是否有正确的程序来限制将要录制的音频量？我想最多10秒。

感谢您提供任何帮助/建议/提示/指示..

   - （BOOL）recordForDuration：（NSTimeInterval）持续时间
  

我认为这样做会有所作为！

I looked for search terms along the lines of the post title, but alas..

I am building an iPhone app using AVFoundation.

Is there a correct procedure to limit the amount of audio that will be recorded? I would like a maximum of 10 seconds.

Thanks for any help/advice/tips/pointers..

解决方案

AVAudioRecorder has the following method:

- (BOOL)recordForDuration:(NSTimeInterval)duration

I think that will do the trick!
