获取iPhone照片曝光信息 [英] Obtaining iPhone Photo Exposure Information

问题描述

有没有办法获取在iPhone上拍摄的照片的曝光设置（光圈，快门速度，ISO）？

Is there any way to get the exposure settings (aperture, shutter speed, ISO) for a photo taken on an iPhone?

在iPhone上运行的应用程序可以使用UIImagePickerController接口拍照，但这并没有提供有关图片的大量信息。

An app running on the iPhone can use the UIImagePickerController interface for taking pictures, but that doesn't provide much info about the picture.

iPhone上拍摄的照片的EXIF数据包含光圈信息，但是不是快门速度或ISO。

The EXIF data for a photo taken on the iPhone contains aperture info, but not shutter speed or ISO.

推荐答案

目前无法使用SDK。如果你觉得这是需要的，我建议你向Apple提交增强请求。

This is not currently possible using the SDK. If it's something you think is needed, I suggest you file an enhancement request with Apple.
