推荐答案

看一下iOS 4.0中新的AV Foundation框架，这个框架提供了从相机捕获视频的（低级）访问。

Have a look at the new AV Foundation framework in iOS 4.0, this framework provides (low-level) access to capturing video from the camera(s).

主要类你需要使用 AVCaptureSession 并且你已经将输出设置为 AVCaptureMovieFileOutput 或 AVCaptureVideoDataOutput 。

The main class you'll need to uses is AVCaptureSession and you'll have set the output to either to AVCaptureMovieFileOutputor AVCaptureVideoDataOutput.
