大佬教程收集整理的这篇文章主要介绍了ios – 有没有办法在swift中将相机设置为横向模式?,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
// 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) 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!
我的预览看起来像那样,那没关系:

但最终看起来像这样:

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 } } }
