ios - 保存旋转的图片(swift3)
<p><p><strong>图片不旋转</strong></p>
<p> <a href="/image/2Cih3.png" rel="noreferrer noopener nofollow"><img src="/image/2Cih3.png" alt="picture without rotation"/></a> </p>
<p><strong>图片旋转</strong></p>
<p> <a href="/image/W2FQY.png" rel="noreferrer noopener nofollow"><img src="/image/W2FQY.png" alt="picture with rotation"/></a> </p>
<p>我要做的就是拍摄旋转保存的照片。就像使用 avfoundation 构建的自定义相机旋转图片一样。现在我的代码拍摄照片并将它们保存到照片库，就像没有旋转的图片一样。 </p>
<pre><code> import UIKit
import AVFoundation
class ViewController: UIViewController, AVCapturePhotoCaptureDelegate {
@IBOutlet var cameraDisplay: UIView!
var captureSession : AVCaptureSession!
var cameraOutput : AVCapturePhotoOutput!
var previewLayer : AVCaptureVideoPreviewLayer!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
captureSession = AVCaptureSession()
captureSession.sessionPreset = AVCaptureSessionPresetPhoto
cameraOutput = AVCapturePhotoOutput()
let device = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo)
if let input = try? AVCaptureDeviceInput(device: device) {
if (captureSession.canAddInput(input)) {
captureSession.addInput(input)
if (captureSession.canAddOutput(cameraOutput)) {
captureSession.addOutput(cameraOutput)
previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
previewLayer.frame = CGRect(x: 10, y: 10, width: 700, height: 700)
cameraDisplay.layer.addSublayer(previewLayer)
captureSession.startRunning()
}}}}
func image(_ image: UIImage, didFinishSavingWithError error: NSError?, contextInfo: UnsafeRawPointer) {
if let error = error {
// we got back an error!
let ac = UIAlertController(title: "Save error", message: error.localizedDescription, preferredStyle: .alert)
ac.addAction(UIAlertAction(title: "OK", style: .default))
present(ac, animated: true)
} else {
let ac = UIAlertController(title: "Image Saved!", message: "Your image has been saved to your photos.", preferredStyle: .alert)
ac.addAction(UIAlertAction(title: "OK", style: .default))
present(ac, animated: true)
}
}
func capture(_ captureOutput: AVCapturePhotoOutput, didFinishProcessingPhotoSampleBuffer photoSampleBuffer: CMSampleBuffer?, previewPhotoSampleBuffer: CMSampleBuffer?, resolvedSettings: AVCaptureResolvedPhotoSettings, bracketSettings: AVCaptureBracketedStillImageSettings?, error: Error?) {
if let sampleBuffer = photoSampleBuffer,
let previewBuffer = previewPhotoSampleBuffer,
let dataImage = AVCapturePhotoOutput.jpegPhotoDataRepresentation(forJPEGSampleBuffer: sampleBuffer, previewPhotoSampleBuffer: previewBuffer){
let dataProvider = CGDataProvider(data: dataImage as CFData)
let cgImageRef: CGImage! = CGImage(jpegDataProviderSource: dataProvider!, decode: nil, shouldInterpolate: true, intent: .defaultIntent)
let imagea = UIImage(cgImage: cgImageRef, scale: 1.0, orientation: UIImageOrientation.right)
UIImageWriteToSavedPhotosAlbum(imagea, self, #selector(self.image(_:didFinishSavingWithError:contextInfo:)), nil)
}}
@IBAction func TakePhoto(_ sender: Any) {
let settings = AVCapturePhotoSettings()
let previewpixel = settings.availablePreviewPhotoPixelFormatTypes.first!
let previewformat = [
kCVPixelBufferPixelFormatTypeKey as String: previewpixel, kCVPixelBufferWidthKey as String: 160,
kCVPixelBufferHeightKey as String : 160]
settings.previewPhotoFormat = previewformat
cameraOutput.capturePhoto(with: settings, delegate: self)
}}

<p><p>更改下一行</p>
<pre><code>UIImage(cgImage: (otherImage?.cgImage!)!, scale: CGFloat(1.0), orientation: .right)
</code></pre>
<p>到</p>
<pre><code>UIImage(cgImage: (otherImage?.cgImage!)!, scale: CGFloat(1.0), orientation: .up)
</code></pre></p>
