如何将相机设置为横向模式?每次我拍照时,图像都会保存为肖像图像。当设备处于横向模式时,照片看起来不错,但如果我在相机胶卷中看到它,它仍然是纵向模式。
这是我的拍照功能:
// take a photo
@IBAction func takePhoto(sender: AnyObject) {
self.fullScreenView.hidden = false
self.recordButton.enabled = false
self.takephoto.enabled = false
self.recordButton.hidden = true
self.takephoto.hidden = true
session.startRunning()
// customize the quality level or bitrate of the output photo
session.sessionPreset = AVCaptureSessionPresetPhoto
// add the AVCaptureVideoPreviewLayer to the view and set the view in fullscreen
fullScreenView.frame = view.bounds
videoPreviewLayer.frame = fullScreenView.bounds
fullScreenView.layer.addSublayer(videoPreviewLayer)
// add action to fullScreenView
gestureFullScreenView = UITapGestureRecognizer(target: self, action: #selector(ViewController.takePhoto(_:)))
self.fullScreenView.addGestureRecognizer(gestureFullScreenView)
// add action to myView
gestureView = UITapGestureRecognizer(target: self, action: #selector(ViewController.setFrontpage(_:)))
self.view.addGestureRecognizer(gestureView)
if (preview == true) {
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 view
if (sampleBuffer != nil) {
let imageData = AVCaptureStillImageOutput.jpegStillImageNSDataRepresentation(sampleBuffer)
let image = UIImage(data: imageData, scale: 1.0)
self.fullScreenView.hidden = true
self.fullScreenView.gestureRecognizers?.forEach(self.fullScreenView.removeGestureRecognizer)
self.session.stopRunning()
// save image to the library
UIImageWriteToSavedPhotosAlbum(image!, nil, nil, nil)
self.imageViewBackground = UIImageView(frame: self.view.bounds)
self.imageViewBackground.image = image
self.imageViewBackground.tag = self.key
self.view.addSubview(self.imageViewBackground)
}
})
}
}
else {
preview = true
}
}
提前致谢!
EDIT
我的预览看起来像这样,没关系:

但最后看起来是这样的:

最佳答案
我用的是这个功能,可能对你有用:
override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
super.viewWillTransitionToSize(size, withTransitionCoordinator: coordinator)
let orientation = UIDevice.currentDevice().orientation
if UIDeviceOrientationIsPortrait(orientation) || UIDeviceOrientationIsLandscape(orientation) {
if let videoOrientation = AVCaptureVideoOrientation(rawValue: orientation.rawValue) {
(captureView.layer as! AVCaptureVideoPreviewLayer).connection.videoOrientation = videoOrientation
}
}
}
