我创建了一个csv文件并尝试通过电子邮件发送它.显示发送邮件的窗口,但不填充电子邮件正文,也没有附加文件.应用程序挂起此屏幕:

按钮"取消"不起作用.在控制台中出现几秒钟后:

viewServiceDidTerminateWithError: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "The operation couldn’t be completed. (_UIViewServiceInterfaceErrorDomain error 3.)" UserInfo=0x7f8409f29b50 {Message=Service Connection Interrupted}

<MFMailComposeRemoteViewController: 0x7f8409c89470> timed out waiting for fence barrier from com.apple.MailCompositionService

有我的代码:

func actionSheet(actionSheet: UIActionSheet!, clickedButtonAtIndex buttonIndex: Int) {
    if buttonIndex == 0 {
        println("Export!")

        var csvString = NSMutableString()
        csvString.appendString("Date;Time;Systolic;Diastolic;Pulse")

        for tempValue in results {     //result define outside this function

            var tempDateTime = NSDate()
            tempDateTime = tempValue.datePress
            var dateFormatter = NSDateFormatter()
            dateFormatter.dateFormat = "dd-MM-yyyy"
            var tempDate = dateFormatter.stringFromDate(tempDateTime)
            dateFormatter.dateFormat = "HH:mm:ss"
            var tempTime …

当我使用iphone 5s的模拟器时,在邮件发送过程中出现这样的错误,并在ios 7模拟器中完美运行.它甚至不显示发送选项,只有在打开邮件发送页面时才会出现取消选项.我该怎么做才能解决它请帮助我.先感谢您
