我的自定义相机在swift 3中运行但是当我更新它时，我试图改变它以使用现在有用的功能
之前的代码：
func photoOutput(_ captureOutput: AVCapturePhotoOutput, didFinishProcessingPhoto photoSampleBuffer: CMSampleBuffer?, previewPhoto previewPhotoSampleBuffer: CMSampleBuffer?, resolvedSettings: AVCaptureResolvedPhotoSettings, bracketSettings: AVCaptureBracketedStillImageSettings?, error: Error?) {
if let unwrappedError = error {
print(unwrappedError.localizedDescription)
} else {
if let sampleBuffer = photoSampleBuffer, let dataImage = AVCapturePhotoOutput.jpegPhotoDataRepresentation(forJPEGSampleBuffer: sampleBuffer, previewPhotoSampleBuffer: previewPhotoSampleBuffer) {
if let finalImage = UIImage(data: dataImage) {
let newImage = finalImage.resizeImage(image: finalImage)
let place = CGPoint(x: newImage.size.width / 2, y: newImage.size.height/2)
Make sure point is within the image
let color = newImage.getPixelColor(pos: place)
print(color)
displayCapturedPhoto(capturedPhoto: finalImage)
}
}
}
}
更改代码:(不会工作）
private func photoOutput(_ output: AVCaptureOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {
if let imageData = photo.fileDataRepresentation() {
if let finalImage = UIImage(data: imageData) {
let newImage = finalImage.resizeImage(image: finalImage)
let place = CGPoint(x: newImage.size.width / 2, y: newImage.size.height/2)
let color = newImage.getPixelColor(pos: place)
print(color)
displayCapturedPhoto(capturedPhoto: finalImage)
}
}
}
我不断收到如下错误：
NSInvalidArgumentException＆＃39;，原因：＆＃39; *** - [AVCapturePhotoOutput capturePhotoWithSettings：delegate：]如果在设置中指定了非零格式字典，则委托必须响应选择器captureOutput：didFinishProcessingPhoto：error ：或者已弃用的captureOutput：didFinishProcessingPhotoSampleBuffer：previewPhotoSampleBuffer：resolvedSettings：bracketSettings：error：
有什么想法吗？
