What's the best way to grab a succession of images from the camera using the AV Foundation framework? 使用AV Foundation框架从摄像机捕获连续图像的最佳方法是什么？ I am only interested in what an iPhone 3G can support. 我只对iPhone 3G可以支持的内容感兴趣。 I haven't been able to find any information on which classes are not supported on the iPhone 3G (without video capability). 我无法找到有关iPhone 3G（不具有视频功能）不支持哪些类的任何信息。

Has anyone had any experience with this? 有没有人有这方面的经验？

Many thanks, Brett 非常感谢，布雷特

All classes are supported on the iPhone 3G. iPhone 3G支持所有类别。 The difference lies in the maximum supported resolution and frame rates as well as in missing hardware capabilities (auto focus, torch, front camera etc.). 区别在于最大支持的分辨率和帧速率以及缺少的硬件功能（自动对焦，手电筒，前置摄像头等）。

If you're a registered developer, you can watch session 409 of the WWDC ( https://developer.apple.com/videos/wwdc/2010/ ). 如果您是注册开发人员，则可以观看WWDC的会话409（ https://developer.apple.com/videos/wwdc/2010/ ）。 They present a few slides where they compare the capabilites and limitations of the different devices. 他们展示了一些幻灯片，比较了不同设备的功能和局限性。
