Question

我有这段代码用于在emailMessageBody中显示一些内容。代码如下。

var emailViewController : MFMailComposeViewController = MFMailComposeViewController()
        emailViewController.mailComposeDelegate = self
        emailViewController.setToRecipients(["----"])
        emailViewController.setSubject("----")
        emailViewController.setMessageBody("\n\n\n" + "-- \r\n " + "----- Device : \(self.deviceName), App Version : \(self.appVersion), Model : \(deviceModel) , iOS Version : \(self.deviceVersion), Country Code : \(self.countryCode), Localised Model : \(deviceLocalizedModel) \n \n \n", isHTML: true)
        self.presentViewController(emailViewController, animated: true, completion: nil)

你们看到我把＆＃34; \ n＆＃34;在内容中，但它没有在emailBody中显示新行。如果有人知道如何在emailMessageBody中获得一些新行，请帮助。

Answer 1

您需要使用</br>代替\n

因此，您的示例代码将如下所示

var emailViewController : MFMailComposeViewController = MFMailComposeViewController()
    emailViewController.mailComposeDelegate = self
    emailViewController.setToRecipients(["----"])
    emailViewController.setSubject("----")
    emailViewController.setMessageBody("</br></br></br>" + "-- </br> " + "----- Device : \(self.deviceName), App Version : \(self.appVersion), Model : \(deviceModel) , iOS Version : \(self.deviceVersion), Country Code : \(self.countryCode), Localised Model : \(deviceLocalizedModel) </br></br></br>", isHTML: true)
    self.presentViewController(emailViewController, animated: true, completion: nil)

Answer 2

如果您想使用\n，则必须在isHTML来电中将参数false设置为setMessageBody，否则您必须使用</br>代替设置邮件正文的内容时\n。
