使用什麼來代替QTCaptureDevice？

Question

我注意到在QTCaptureDevice（https://developer.apple.com/library/mac/documentation/quicktime/reference/QTCaptureDevice_Class/Reference/Reference.html）的文檔中，它似乎正在被折舊？

你應該用什麼來代替做屏幕/錄音？

QTKit已被淘汰，建議您使用AVFoundation。它提供similiar功能，在這種情況下更

使用AVCaptureDevice做出AVCaptureSession

例如建立一個攝像機視圖

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];
