为什么我的纵向拍摄的照片会变成横向？

Question

我有这个 cameraView，最重要的是我有这个 UIImageView。 UIImageView 基本上是一个改变cameraView颜色的滤镜。 我可以使用下面的代码拍照，output 图像将纵向图像更改为横向。 为什么会这样？ 谢谢！

@IBAction func takePicture(_ sender: Any) {

let settings = AVCapturePhotoSettings(format: [AVVideoCodecKey: AVVideoCodecType.jpeg])
stillImageOutput.capturePhoto(with: settings, delegate: self)

}


func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: 
AVCapturePhoto, error: Error?) {

let renderer = UIGraphicsImageRenderer(size: view.bounds.size)

let image = renderer.image { ctx in
view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)

}


if let imageData = photo.fileDataRepresentation() {
if let cameraImage = UIImage(data: imageData) {

let newImage = self.composite(image:cameraImage, overlay: image, scaleOverlay:true)
captureImageView.image = newImage

    }
  }
}

//combine imageview with uiview

func composite(image:UIImage, overlay:(UIImage), scaleOverlay: Bool = false)->UIImage?{

UIGraphicsBeginImageContext(image.size)
var rect = CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height)
image.draw(in: rect)
if scaleOverlay == false {
    rect = CGRect(x: 0, y: 0, width: overlay.size.width, height: overlay.size.height)
}
overlay.draw(in: rect)
return UIGraphicsGetImageFromCurrentImageContext()
}
