本篇文章为大家展示了原生AVCapture怎么在iOS中使用,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
<强>概述:
可用于音频、二维码,拍的照,录制视频(均可自定义界面)
<强>常见的输出信号:
AVCaptureAudioDataOutput音频输出
<李>AVCaptureFileOutput文本输出
<李>AVCaptureMetadataOutput二维码条形码…
<李>AVCaptureStillImageOutput拍照
<李>AVCaptureMovieFileOutput录制视频(不能实现暂停录制和定义视频文件类型)
<李>AVCaptureVideoDataOutput + AVCaptureAudioDataOutput录制视频的灵活性更强(能实现暂停录制和定义视频文件类型)
<强> AVCaptureMovieFileOutput输出流实现视频录制
初始化会话层
创建预览图层
录制视频
结束录制
拍摄视频保存路径
会话层启动和关闭
代理方法
