我有一个 PDF 文档存储在我的应用程序的主包中,还有一个带有文本字段供用户输入的 ViewController。我还有一个按钮,可以将填写好的 PDF 通过电子邮件发送给用户。我不需要将 PDF 保存到设备
我想使用 PDFKit 来做到这一点,但我无法弄清楚如何实现这一点。
我尝试了以下代码:
if let path = Bundle.main.path(forResource: "User", ofType: "pdf") {
let url = URL(fileURLWithPath: path)
if let doc = PDFDocument(url: url) {
for index in 0..<doc!.pageCount{
if let page = doc?.page(at: index){
let annotations = page.annotations
for annotation in annotations{
print("Annotation Name :: \(annotation.fieldName ?? "")")
if annotation.fieldName == "firstname"{
annotation.setValue(firstnameField.text, forAnnotationKey: .widgetValue)
page.removeAnnotation(annotation)
page.addAnnotation(annotation)
}
}
}
}
let mailComposer = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
mailComposer.setToRecipients([emailField.text])
mailComposer.setSubject("User Information")
mailComposer.setMessageBody("User Information for \(firstnameField.text).", isHTML: true)
mailComposer.addAttachmentData(doc.dataRepresentation()!, mimeType: "application/pdf", fileName: "User")
self.present(mailComposer, animated: true, completion: nil)
}
}
对此的任何帮助将不胜感激。
