我试图从一个网站获取JSON并解析它，然后将其放入iOS视图。
这里是我的代码;
func startConnection(){
let urlPath: String = "http://binaenaleyh.net/dusor/"
var url: NSURL = NSURL(string: urlPath)
var request: NSURLRequest = NSURLRequest(URL: url)
var connection: NSURLConnection = NSURLConnection(request: request,delegate: self,startImmediately: false)
connection.start()
}
func connection(connection: NSURLConnection!,didReceiveData data: NSData!){
self.data.appendData(data)
}
func buttonAction(sender: UIButton!){
startConnection()
}
func connectionDidFinishLoading(connection: NSURLConnection!) {
var err: NSError
// throwing an error on the line below (can't figure out where the error message is)
var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data,options: NSJSONReadingOptions.MutableContainers,error: nil) as NSDictionary
}
这是JSON的链接;

我在这里做错了什么？
这两个函数为我工作：
原文链接：https://www.f2er.com/swift/321079.htmlfunc getJSON(urlToRequest: String) -> NSData{
return NSData(contentsOfURL: NSURL(string: urlToRequest))
}
func parseJSON(inputData: NSData) -> NSDictionary{
var error: NSError?
var boardsDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(inputData,error: &error) as NSDictionary
return boardsDictionary
}
