objective-c - 使用什么来代替 QTCaptureDevice？

Question

我注意到在 QTCaptureDevice ( https://developer.apple.com/library/mac/documentation/quicktime/reference/QTCaptureDevice_Class/Reference/Reference.html ) 的文档中它似乎正在贬值？

您应该使用什么来进行屏幕/音频录制？

Answer 1

QTKit 已被淘汰，我们鼓励您使用 AVFoundation。它提供类似的功能以及更多

在本例中使用 AVCaptureDevice 来创建 AVCaptureSession

例如设置相机 View

AVCaptureDevice * captureDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
AVCaptureDeviceInput * captureDeviceInput = [AVCaptureDeviceInput deviceInputWithDevice:captureDevice error:error];

AVCaptureSession * captureSession = [[AVCaptureSession alloc] init];    
[captureSession beginConfiguration];
captureSession.sessionPreset = AVCaptureSessionPresetPhoto;
[captureSession addInput:captureDeviceInput];
AVCaptureStillImageOutput * output = [[AVCaptureStillImageOutput alloc] init];
[captureSession addOutput:output];

[captureSession commitConfiguration];    
[captureSession startRunning];
