Question

目标：实施包含Gmail作为选项的共享表（UIActivityViewController），并设置收件人和主题

问题：设置主题有效，但设置收件人（forKey：＆＃34;到＆＃34;）会导致程序崩溃。

我希望能够设置共享表电子邮件客户端的发件人和收件人字段，但到目前为止，我一直无法找到任何方法。任何帮助表示赞赏！

相关代码：

let email = ["bob@bobsCompany.com"]
let activityVC = UIActivityViewController(activityItems: [""], applicationActivities: nil)

activityVC.excludedActivityTypes = excludedActivity

activityVC.setValue("Subject Title", forKey: "subject")

activityVC.setValue(email[0], forKey: "to")

activityVC.popoverPresentationController?.sourceView = self.view
self.presentViewController(activityVC, animated: true, completion: nil)

Answer 1

您只能为UIActivityViewController设置Subject。该程序崩溃，因为没有“到”键。如果要设置收件人和发件人字段，则必须使用MailMFComposeViewController。

    if !MFMailComposeViewController.canSendMail()
    {
      let alertMsg = UIAlertController(title: "Test", message: "Mail services not available.", preferredStyle: UIAlertControllerStyle.Alert)
      alertMsg.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
      self.presentViewController(alertMsg, animated: true, completion: nil)
    }
    else
    {
      let composeVC = MFMailComposeViewController()
      composeVC.mailComposeDelegate = self

      // Configure the fields of the interface.
      composeVC.setToRecipients(["mail@egmail.com"])
      composeVC.setSubject("Subject)
      composeVC.setMessageBody("Hi.", isHTML: false)

      // Present the view controller modally.
      self.presentViewController(composeVC, animated: true, completion: nil)
    }

从共享表（ios）设置电子邮件发件人和收件人
