如何使用pdfkit通过相机拍摄的图像创建pdf [英] how to create a pdf from image which taken by camera with pdfkit

问题描述

您好我是 pdfkit 和iOS应用程序的新手，我想用设备拍照，然后将图像转换为pdf。使用相机拍照并将其保存在相机胶卷上工作完全正常，问题是当我想从该图像创建pdf时它需要图像的名称，我怎么能找到它？
和另一个问题是可以用 pdfkit 实现任何pdf编辑器来编辑图像吗？
感谢任何帮助。下面是我的 imagePickerController 代码。

Hi I am new to pdfkit and iOS applications, I want to take a picture with device and then convert the image to pdf. taking pictures with camera and saving it on Camera Roll works completely fine, the problem is when I want to create pdf from that image it needs the name of the image, how I can find it? and another question is it possible to implement any pdf editor with pdfkit to edit image? Appreciate any help. below is my imagePickerController codes.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage

    if (Mylibrary)
    {

    }
    else
    {
        UIImageWriteToSavedPhotosAlbum(pickedImage!, nil, nil, nil);
        let image = UIImage(named: "????") //the problem is here
        let newPage = PDFPage(image: image!)
    }

    picker.dismiss(animated: true, completion: nil)




}

推荐答案

由于图像已经存储在 pickedImage 变量。您只需要使用 pickedImage 初始化新的 PDFPage 对象。使用 ImageKit 编辑图像，然后再使用它初始化新的 PDFPage 对象。

There's no need to instantiate a new image since the image is already stored in the pickedImage variable. You just need to initialize the new PDFPage object with pickedImage. Use ImageKit to edit the image before using it to initialize a new PDFPage object.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    guard let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage else { return }

    // Adds pickedImage to the user’s Camera Roll album.
    UIImageWriteToSavedPhotosAlbum(pickedImage, nil, nil, nil)
    // Creates a new PDFPage object and initializes it with pickedImage.
    let newPage = PDFPage(image: pickedImage)

    dismiss(animated: true, completion: nil)
}
