iPhone上的UIImagePickerController和AVCaptureSession之间的相机差异 [英] Camera differences between UIImagePickerController and AVCaptureSession on iPhone

问题描述

我尝试使用 AVCaptureSession 替 UIImagePickerController c> 和 AVCaptureStillImageOutput

I'm trying to build a replacement for UIImagePickerController, using AVCaptureSession with AVCaptureDeviceInput and AVCaptureStillImageOutput, as input/output respectively.

要预览相机流，我使用 AVCaptureVideoPreviewLayer 。

To preview the camera stream I'm using AVCaptureVideoPreviewLayer.

它现在可以像捕获和存储照片一样正常工作。

It's now working correctly for capturing and storing photos just like the default camera.

问题我无法解决：

• 拍摄的照片的质量与默认照相机不同



• 无法控制相机特定选项（例如闪光灯）

有任何方法可以使用更定制的方法到达 UIImagePickerController （ AVFoundation 或任何其他）？

Is there any way to get to the level of UIImagePickerController using a more customizable approach (i.e. AVFoundation or any other)?

推荐答案

409 - 使用相机与AV基金会的 WWDC 2010视频。根据视频， 就像您可以用 AVFoundation 解决所有三个问题。

Check out "Session 409 - Using the Camera with AV Foundation" in the WWDC 2010 videos. Based on the video, it looks like you can resolve all three of your issues with AVFoundation.
