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
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 { } }
