用什么代替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，它似乎正在折旧？

你应该用什么代替进行屏幕/录音？

Answer 1

QTKit逐步淘汰，我们鼓励您使用AVFoundation。它提供了类似的功能和更多

在这种情况下使用AVCaptureDevice来制作AVCaptureSession

e.g。设置相机视图

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];
