Question

当我使用相机在我的应用程序中拍照时，图像会被颠倒显示。

我使用UIImagePickerController拍摄照片，然后选择我喜欢的照片。选择后，执行以下功能：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    print("image selected ...")
    // Get picked image info dictionary
    let image = info[UIImagePickerControllerOriginalImage] as! UIImage
    // Image is upside down. Need to re-orient


    // Add captured and selected image to your Photo Library
    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)

    // Create PDFDocument object and display in PDFView
    let document = createPDFDataFromImage(image: image)

    myPDFView.document = document

    // Dimiss imagePicker
    dismiss(animated: true, completion: nil)

}


func createPDFDataFromImage(image: UIImage) -> PDFDocument{
    let document = PDFDocument.init()
    let imagePDF = PDFPage.init(image: image)

    document.insert(imagePDF!, at: 0)
    return document
}

如何阻止图片颠倒？

Answer 1

这是一种方法：

    var flippedImage: UIImage?

    if let origImage = UIImage(named: "s1") {
        if let cg = origImage.cgImage {
            flippedImage = UIImage(cgImage: cg, scale: 1.0, orientation: UIImageOrientation.downMirrored)
        }
    }

    theImageView.image = flippedImage

在我的应用程序中使用相机拍摄的照片是颠倒的
