在UIView中嵌入实时相机视图 [英] embed live camera view inside a UIView

问题描述

我一直在想办法在iPhone的 UIView 里面嵌入一个小的（ish）实时相机视图。

我甚至没有能够在网上找到任何样品。我知道它是可行的，但我甚至不知道从哪里开始。似乎有很多例子，其他人已添加视图到相机的完整的屏幕视图，而不是其他方式...

I've been trying to figure out how to embed a small(ish) live camera view inside of an iPhone's UIView to no avail.
I have not even been able to find any samples of that on the net either. I know that it's do-able, but I don't even know where to start. There seem to be a lot of examples where others have added views TO the full-blown screen view of the camera, but not the other way around...

似乎 UIImagePickerControllerSourceTypeCamera 只是显示大模态摄像机
查看器，图片接收器，因此它不适合我的目的

It seems that UIImagePickerControllerSourceTypeCamera just displays the BIG modal camera viewer, picture taker, so it is unsuitable (I think) for my purposes.

我想有一个小的活的相机视图，在 UIView 里面，我可以添加我自己的按钮
采取pic我可以想出这个 - 一个代表以某种形式捕获
的图像）

I want to have a small live camera view, inside a UIView, and I can add my own buttons for taking the pic (I can probably figure this out - a delegate of some sort to capture the image)

谢谢...

出于您的目的，您需要使用 AVFoundation ，具体看看 AVCaptureSession ， AVCaptureDeviceInput 您可以使用它来访问摄像机，并查看 AVCaptureVideoPreviewLayer ，这将允许您将相机输入绘制到屏幕，所需的一切是在那里..
