以及它似乎要崩溃的代码

func insertUserConfirmedIntoDatabase(){

    let defaults = NSUserDefaults.standardUserDefaults()
    defaults.synchronize()

    var parameters = ""

    if let YouTubeChannelID = defaults.valueForKey("YTchannelID"){
        parameters = "YouTubeChannelID=\(YouTubeChannelID)&"
    }

    if let  TwitterID = defaults.valueForKey("chosenTwitterID"){
        parameters = parameters.stringByAppendingString("TwitterID=\(TwitterID)&")
    }

    if      let Subscribers = defaults.valueForKey("YTchannelsubscriberCount"){
        parameters = parameters.stringByAppendingString("Subscribers=\(Subscribers)&")
    }

    if  let VloggerYouTubeName = defaults.valueForKey("YTchannelName"){
        parameters = parameters.stringByAppendingString("VloggerYouTubeName=\(VloggerYouTubeName)&")        }


    if let VloggersEmail = defaults.valueForKey("usersEmail"){
        parameters = parameters.stringByAppendingString("VloggersEmail=\(VloggersEmail)&")
    }

    if let  VloggersUserID = defaults.valueForKey("userGoogleID"){
        parameters = parameters.stringByAppendingString("VloggersUserID=\(VloggersUserID)&")
    }

    if  let VloggersCountry = defaults.valueForKey("YTchannelCountry"){

    }


    let url = NSURL(string: "https://website.com/TMVUKApp/updateProfile.php?\(parameters)")!
    print("if let params \(url)")


    let request = NSURLRequest(URL: url)

    let session = NSURLSession.sharedSession()

    let task = session.dataTaskWithRequest(request) {

        (data, response, error) -> Void in

        if error == nil{

            self.performSegueWithIdentifier("loggedInSegue", sender: nil)
        }
    }

    task.resume()

}
以及调用

插入器确认数据库

这是仅发生在1个用户身上的崩溃之一。我最初认为这可能是由于一些NSUserDefaults没有设置，但我已经用if-let语句处理了它们，但仍然崩溃了

在帮助我调试这个问题时，我们将一如既往地感激您的帮助。
它为什么会崩溃？

我猜与session.dataTaskWithRequest调用有关。试着在调用代码之前让你的应用进入一个状态，然后关闭你所有的互联网连接，并执行任何你想触发代码运行的操作。这将在使用APP的过程中“模拟”一个丢失的连接。

我最近发现了一些非常相似的问题，用户崩溃和丢失了他们的证书。日志显示：

    1.087128     CFNetwork                  0x0000000183f74394 Faulting in NSHTTPCookieStorage singleton
我使用setValue已经几个月了，几周前就开始崩溃了。将setValue更改为setObject似乎有帮助。过去几天没有问题。等待AppStore发布。

可能没有解决方案，但这里有一些注意事项：您调用的同步太多，只能在写入操作后使用它•不要使用valueForKey/setValueForKey:，它们是特殊的KVC方法，使用objectForKey/setObjectForKey:并将其强制转换为适当的类型，例如，如果让VloggersEmail=defaults.objectForKeyusersEmail为？字符串{•对于查询参数NSURLComponents/NSQueryItems是一个更好的解决方案，因为它在必要时对字符串进行百分比编码。接受作为请求的答案。特别是其中一个用户有一个特殊字符需要转义
