Question

我尝试使用UIActivityViewController共享csv文件我想通过电子邮件和Telegram等其他应用程序分享通过Telegram，文件可以正确共享，但使用电子邮件，电子邮件没有附件另外，csv文件没有扩展名，我应该设置MIME类型吗？怎么样？

 @IBAction func shareSheet(sender: AnyObject) {

    let firstActivityItem = "Hi, here is the csv file"

    //do i really need this? what for?
    let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!

    let csv : NSData! = NSData(contentsOfFile: NSTemporaryDirectory() + "export.csv")

    let activityViewController : UIActivityViewController = UIActivityViewController(
        activityItems: [firstActivityItem, secondActivityItem, csv], applicationActivities: nil)

    //set the email title
    activityViewController.setValue(firstAcxtivityItem, forKey: "subject")


    self.presentViewController(activityViewController, animated: true, completion: nil)
}

这是我用于通过邮件编写器发送CSV的代码

let csvString = "Your CSV String"
    let subject = "Subject of your email"
    let fileName = "CSV Filename.csv"

    let composeVC = MFMailComposeViewController()
    composeVC.mailComposeDelegate = self
    composeVC.setSubject(subject)

    if let csvData = csvString.data(using: String.Encoding.utf8) {
        composeVC.addAttachmentData(csvData, mimeType: "text/csv", fileName: fileName)
    }

    self.present(composeVC, animated: true, completion: nil)
