这些是拍摄照片的步骤。
在您的clickCapture方法上具有以下代码，并且不要忘记在类中进行确认和实现委托。
let settings = AVCapturePhotoSettings()
let previewPixelType = settings.availablePreviewPhotoPixelFormatTypes.first!
let previewFormat = [kCVPixelBufferPixelFormatTypeKey as String: previewPixelType,
kCVPixelBufferWidthKey as String: 160,
kCVPixelBufferHeightKey as String: 160,
]
settings.previewPhotoFormat = previewFormat
self.cameraOutput.capturePhoto(with: settings, delegate: self)
如果您打算通过视频连接拍摄照片。您可以按照以下步骤操作。
if let videoConnection = stillImageOutput!.connectionWithMediaType(AVMediaTypeVideo) {
// ...
// Code for photo capture goes here...
}
stillImageOutput?.captureStillImageAsynchronouslyFromConnection(videoConnection, completionHandler: { (sampleBuffer, error) -> Void in
// ...
// Process the image data (sampleBuffer) here to get an image file we can put in our captureImageView
})
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)
// ...
// Add the image to captureImageView here...
}
根据您的需要将图像保存到照片库或在图像视图中显示
