我将MFMailcomposeViewController用于邮件功能。
但是当应用程序存在MFMailComposeViewController时,toReceipts字段中的文本会延迟显示。为什么这样?

if MFMailComposeViewController.canSendMail()
  {
    var mailPicker = MFMailComposeViewController()
    mailPicker.mailComposeDelegate = self;
    mailPicker.setSubject("hello");
    mailPicker.setMessageBody(txtViewBody.text, isHTML: false);
    mailPicker.setToRecipients(["[email protected]"])

    self.becomeFirstResponder();


    presentViewController(mailPicker, animated: true, completion: {
        println("Mail composer completion block")
    });

    }

最佳答案

它将在模拟器中显示带有延迟的收件人。
在设备中,它不会延迟加载。
