使用自定义相机Swift 3拍照

在Swift 2.3中，我使用以下代码在自定义相机中拍照：

 func didPressTakePhoto(){
        if let videoConnection = stillImageOutput!.connection(withMediaType: AVMediaTypeVideo) {
            stillImageOutput?.captureStillImageAsynchronouslyFromConnection(videoConnection, completionHandler: { (sampleBuffer, error) -> Void in
                if sampleBuffer != nil {
                    let imageData = AVCaptureStillImageOutput.jpegStillImageNSDataRepresentation(sampleBuffer)
                    let dataProvider = CGDataProviderCreateWithCFData(imageData)
                    let cgImageRef = CGImageCreateWithJPEGDataProvider(dataProvider, nil, true, CGColorRenderingIntent.RenderingIntentDefault)
                    let image = UIImage(CGImage: cgImageRef!, scale: 1.0, orientation: UIImageOrientation.Right)
                    self.captureImageView.image = image
                }
            })
    }
}

但是他的话：

stillImageOutput?.captureStillImageAsynchronouslyFromConnection(videoConnection,

completionHandler: { (sampleBuffer, error) -> Void in

显示此错误：

类型“ AVCapturePhotoOutput”的值没有成员“

captureStillImageAsynchronouslyFromConnection”

我尝试解决问题，但是我总是收到越来越多的错误，所以这就是我发布原始代码的原因。

有人知道如何使我的代码再次起作用吗？

谢谢。

多亏了Sharpkits，我找到了解决方案（此代码对我有用）：

func capture(_ captureOutput: AVCapturePhotoOutput, didFinishProcessingPhotoSampleBuffer photoSampleBuffer: CMSampleBuffer?, previewPhotoSampleBuffer: CMSampleBuffer?, resolvedSettings: AVCaptureResolvedPhotoSettings, bracketSettings: AVCaptureBracketedStillImageSettings?, error: Error?) {
        if let error = error {
            print(error.localizedDescription)
        }
        if let sampleBuffer = photoSampleBuffer, let previewBuffer = previewPhotoSampleBuffer,
            let dataImage = AVCapturePhotoOutput.jpegPhotoDataRepresentation(forJPEGSampleBuffer: sampleBuffer, previewPhotoSampleBuffer: previewBuffer) {
            let imageData = AVCapturePhotoOutput.jpegPhotoDataRepresentation(forJPEGSampleBuffer: sampleBuffer, previewPhotoSampleBuffer: nil)
            let dataProvider = CGDataProvider(data: imageData as! CFData)
            let cgImageRef = CGImage(jpegDataProviderSource: dataProvider!, decode: nil, shouldInterpolate: true, intent: CGColorRenderingIntent.absoluteColorimetric)
            let image = UIImage(cgImage: cgImageRef!, scale: 1.0, orientation: UIImageOrientation.right)
            let cropedImage = self.cropToSquare(image: image)
            let newImage = self.scaleImageWith(cropedImage, and: CGSize(width: 600, height: 600))
            print(UIScreen.main.bounds.width)
            self.tempImageView.image = newImage
            self.tempImageView.isHidden = false
        } else {
        }
    }
