如何为Swift实现AVCam [英] How to implement AVCam for Swift

问题描述

您好，我找到两个关于AVCam的链接

1. Apple： https://developer.apple.com/library/ios/samplecode/AVCam/History/History.html


2. alex-chan / AVCamSwift： https://github.com/alex-chan / AVCamSwift

第一个链接的演示文件可以正常工作，但它在Object-C关于将Object-C转换为Swift的文档？

第二个链接我已经下载了文件，但它不会在我的4s运行 - 有人可以告诉我为什么？ >

我想有一个swift版本，所以我可以很容易地采用它到我的swift build +感谢再次SO！

解决方案

如果你有一个工作objc版本为什么不只是导入它与桥接头？没有一个关于将obj-c转换为swift的文档，如果你真的想转换它，你需要逐行执行。

你想做什么？获得实时相机馈送显示？这些文档已被移植到swift并适合这个目的，但您需要先获取输入端口。

https://developer.apple.com/library/mac /documentation/AVFoundation/Reference/AVCaptureVideoPreviewLayer_Class/index.html#//apple_ref/occ/clm/AVCaptureVideoPreviewLayer/layerWithSession ：

更新：如何导入obj -c头文件，一种更新的方式来创建它们，但是没有谈到的只是创建任何正常的.m文件或​​目标c文件，然后选择是创建一个briding标头，它配置一切为你。
据说，在尝试实现此类功能之前，如果您遇到关于链接的问题，可能需要更多地了解一些基本知识，或者遵循一些指南。

以下是随机应用程式制作指南 http://www.ioscreator.com/tutorials/calculator-tutorial-in-ios8-with-swift ，应该教你多少。我会推荐跟随和阅读这样的东西，直到你有一个更多的基础，并可以提出更多的确切问题。没有人会在这里为你重写苹果程序，你的问题是非常广泛的。

Hello I have found two links about AVCam

1. Apple: https://developer.apple.com/library/ios/samplecode/AVCam/History/History.html
2. alex-chan/AVCamSwift: https://github.com/alex-chan/AVCamSwift

The first link has demo files that work perfectly, but its in Object-C - can someone show me documentation on converting Object-C to Swift?

The second link I have downloaded the files but it will not run in my 4s - can someone tell me why?

I would like to have a swift version so I can easily adopt it into my swift build + thanks again SO!

解决方案

if you have a working objc version why not just import it with a bridging header? there is no one document about converting obj-c to swift, if you really want to convert it you are going to need to do it line by line.

also what exactly are you trying to do? get a live camera feed displayed? these docs have been ported to swift and would suit that purpose but you would need to get the input port first.

https://developer.apple.com/library/mac/documentation/AVFoundation/Reference/AVCaptureVideoPreviewLayer_Class/index.html#//apple_ref/occ/clm/AVCaptureVideoPreviewLayer/layerWithSession:

Update: how to import obj-c headers, a newer way to create them that isnt quite as talked about yet is to just create any normal .m file or objective c file then select yes to creating a briding header, it configures everything for you. That being said it may be worth while to play around with the basics a bit more and maybe follow a few guides before attempting to implement this type of feature if you are having issues with following the links.

Here is a random application creation guide http://www.ioscreator.com/tutorials/calculator-tutorial-in-ios8-with-swift that should teach you alot. i would recommend following and reading through stuff like this until you have a bit more of a footing and can come up with more of an exact question. no one here is going to rewrite the apple program for you and your questions are extremely broad.
