public func UPLOADIMG(url: String,parameters: Dictionary<String,AnyObject>?,filename:String,image:UIImage, success:((NSDictionary) -> Void)!, failed:((NSDictionary) -> Void)!, errord:((NSError) -> Void)!) {
        var TWITTERFON_FORM_BOUNDARY:String = "AaB03x"
        let url = NSURL(string: url)!
        var request:NSMutableURLRequest = NSMutableURLRequest(URL: url, cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 10)
        var MPboundary:String = "--\(TWITTERFON_FORM_BOUNDARY)"
        var endMPboundary:String = "\(MPboundary)--"
        //convert UIImage to NSData            
        var data:NSData = UIImagePNGRepresentation(image)
        var body:NSMutableString = NSMutableString();
        // with other params
        if parameters != nil {
            for (key, value) in parameters! {
                body.appendFormat("\(MPboundary)\r\n")
                body.appendFormat("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
                body.appendFormat("\(value)\r\n")
            }
        }
        // set upload image, name is the key of image 
        body.appendFormat("%@\r\n",MPboundary)
        body.appendFormat("Content-Disposition: form-data; name=\"\(filename)\"; filename=\"pen111.png\"\r\n")
        body.appendFormat("Content-Type: image/png\r\n\r\n")
        var end:String = "\r\n\(endMPboundary)"
        var myRequestData:NSMutableData = NSMutableData();
        myRequestData.appendData(body.dataUsingEncoding(NSUTF8StringEncoding)!)
        myRequestData.appendData(data)
        myRequestData.appendData(end.dataUsingEncoding(NSUTF8StringEncoding)!)
        var content:String = "multipart/form-data; boundary=\(TWITTERFON_FORM_BOUNDARY)"
        request.setValue(content, forHTTPHeaderField: "Content-Type")
        request.setValue("\(myRequestData.length)", forHTTPHeaderField: "Content-Length")
        request.HTTPBody = myRequestData
        request.HTTPMethod = "POST"
        //        var conn:NSURLConnection = NSURLConnection(request: request, delegate: self)!
        let task = NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: {
            data, response, error in
            if error != nil {
                println(error)
                errord(error)
                return
            }
            var parseError: NSError?
            let responseObject: AnyObject? = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: &parseError)
            if let responseDictionary = responseObject as? NSDictionary {
                success(responseDictionary)
            } else {
            }

        })
        task.resume()

}
