我一直在使用自定义相机,最近我和Swift 3一起升级到Xcode 8 beta.我原来是这样的:

var stillImageOutput: AVCaptureStillImageOutput?

但是,我现在收到警告:

在iOS 10.0中不推荐使用'AVCaptureStillImageOutput':改用AVCapturePhotoOutput

由于这是相当新的,我没有看到很多关于此的信息.这是我目前的代码:

var captureSession: AVCaptureSession?
var stillImageOutput: AVCaptureStillImageOutput?
var previewLayer: AVCaptureVideoPreviewLayer?

func clickPicture() {

    if let videoConnection = stillImageOutput?.connection(withMediaType: AVMediaTypeVideo) {

        videoConnection.videoOrientation = .portrait
        stillImageOutput?.captureStillImageAsynchronously(from: videoConnection, completionHandler: { (sampleBuffer, error) -> Void in

            if sampleBuffer != nil {

                let imageData = AVCaptureStillImageOutput.jpegStillImageNSDataRepresentation(sampleBuffer)
                let dataProvider = CGDataProvider(data: imageData!)
                let cgImageRef = CGImage(jpegDataProviderSource: dataProvider!, decode: nil, shouldInterpolate: true, intent: .defaultIntent)

                let image = UIImage(cgImage: cgImageRef!, scale: 1, orientation: .right)

            }

        })

    }

} …
