用自定义相机Swift 3拍照 [英] Taking photo with custom camera Swift 3

问题描述

在Swift 2.3中我使用此代码在自定义相机中拍照：

in Swift 2.3 I used this code to take a picture in custom camera:

 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
                }
            })

    }
}

但他的行： stillImageOutput？.captureStillImageAsynchronouslyFromConnection（videoConnection，completionHandler：{（sampleBuffer，error） - >无效

显示此错误：

AVCapturePhotoOutput类型的值没有成员
'captureStillImageAsynchronouslyFromConnection'

Value of type 'AVCapturePhotoOutput' has no member 'captureStillImageAsynchronouslyFromConnection'

我尝试解决了我的问题，但我总是得到更多更多错误，这就是我发布原始代码的原因。

I tried solving my problem but I always get more and more errors so that is why I post my original code.

有人知道如何让我的代码再次运行吗？

Does anybody know how to make my code work again?

谢谢。

推荐答案

感谢Sharpkits我发现了我的解决方案（此代码适用于我）：

Thanks to Sharpkits I found my solution (This code works for me):

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 {

        }
    }
