Question

在我的代码中

class DocViewController: UIViewController,UITextViewDelegate, MFMailComposeViewControllerDelegate{
    var result:String!
    override func viewDidLoad() {
        super.viewDidLoad()
        result = "/Test - " + dateToday!
        func getPDFFileName(_ name: String) -> String {
            let newPDFName = "\(name).pdf"
            let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
            let documentsDirectory = paths[0]
            let pdfFileName: String = (documentsDirectory as String).appending(newPDFName);
            print(pdfFileName)
            return pdfFileName
        }
        @IBAction func sendMail(_ sender: UIBarButtonItem) {
            let mailComposeViewController = configuredMailComposeViewController()
            if MFMailComposeViewController.canSendMail() {
                self.present(mailComposeViewController, animated: true, completion: nil)
            } else {
                self.showSendMailErrorAlert()
            }
        }
        func configuredMailComposeViewController() -> MFMailComposeViewController {
            let mailComposer:MFMailComposeViewController = MFMailComposeViewController()
            mailComposer.mailComposeDelegate = self
            let recipients = ["a@a.com"]
            //Set the subject and message of the email
            mailComposer.setToRecipients(recipients)
            mailComposer.setSubject("Test")
            mailComposer.setMessageBody("Send Saved PDF File", isHTML: false)

            if let filePath = Bundle.main.path(forResource: getPDFFileName(result), ofType: "pdf") {
                print("File path loaded.")

                if let fileData = NSData(contentsOfFile: filePath) {
                    print("File data loaded.")
                    mailComposer.addAttachmentData(fileData as Data, mimeType: "application/pdf", fileName: "pdf")
                }
                present(mailComposer, animated: true, completion: nil)
            }
            return mailComposer
        }

我正在创建pdf并希望通过邮件发送。邮件有效。但是没有附上pdf。如果我使用模拟器，则目录为/Users/xxxxxx/Library/Developer/CoreSimulator/Devices/91BD76E3-7BD6-49E9-87E7-63C87BE980EF/data/Containers/Data/Application/16350B51-6898-45AA-BEF3-F0B0E4FF7556/Documents/Test - Monday, 25 December 2017.pdf

如果我使用iPhone，保存目录是：当我尝试附加邮件时，/var/mobile/Containers/Data/Application/7374E0A1-3E49-494D-B554-1D9C761FC7C1/Documents/Test - Monday, 25 December 2017.pdf和控制台消息为2017-12-25 20:36:45.344149+0530 Karma[7690:1157301] [App] if we're in the real pre-commit handler we can't actually add any new fences due to CA restriction。我哪里做错了？如何指定iPhone的相同位置来附加创建的pdf文件？请帮忙。

编辑：下面的代码工作并附加创建的pdf与邮件：

class DocViewController: UIViewController,UITextViewDelegate, MFMailComposeViewControllerDelegate{
    var result:String!
    override func viewDidLoad() {
        super.viewDidLoad()
        result = "/Test - " + dateToday!
        func getPDFFileName(_ name: String) -> String {
            let newPDFName = "\(name).pdf"
            let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
            let documentsDirectory = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)[0] as! String
            let pdfFileName: String = (documentsDirectory as String).appending(newPDFName);
            print(pdfFileName)
            return pdfFileName
        }
        @IBAction func sendMail(_ sender: UIBarButtonItem) {
            let mailComposeViewController = configuredMailComposeViewController()
            if MFMailComposeViewController.canSendMail() {
                present(mailComposeViewController, animated: true, completion: nil)
            } else {
                self.showSendMailErrorAlert()
            }
        }
        func configuredMailComposeViewController() -> MFMailComposeViewController {
            let mailComposer:MFMailComposeViewController = MFMailComposeViewController()
            mailComposer.mailComposeDelegate = self
            let recipients = ["a@a.com"]
            //Set the subject and message of the email
            mailComposer.setToRecipients(recipients)
            mailComposer.setSubject("Test")
            mailComposer.setMessageBody("Send Saved PDF File", isHTML: false)
            let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)[0] as! String

            let filePath = getPDFFileName(result)
                print("File path loaded.")

                if let fileData = NSData(contentsOfFile: filePath) {
                    print("File data loaded.")
                    mailComposer.addAttachmentData(fileData as Data, mimeType: "application/pdf", fileName: result)

                self.present(mailComposer, animated: true, completion: nil)
            }
            return mailComposer
        }
}
