想要上传6张图片。 this is my controller view, after clicking save it want to store at server
func myImageUploadRequest()
{
let myUrl = NSURL(string: "http://easemyshop.in/upload_test/new.php");
//let myUrl = NSURL(string: "http://easemyshop.in/upload_test/new.php");

request.httpMethod = "POST";
let param = [
"tag" : "all",

let boundary = generateBoundaryString()
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
let imageData = UIImageJPEGRepresentation((imageView?.image!)!, 1)
if(imageData==nil) { return; }
request.httpBody = createBodyWithParameters(parameters: param, filePathKey: "file", imageDataKey: imageData! as NSData, boundary: boundary) as Data
myActivityIndicator.isHidden = false
myActivityIndicator.startAnimating();
let task = URLSession.shared.dataTask(with: request as URLRequest)
{
data, response, error in
if error != nil
{
print("******** error=\(error)")
return

// You can print out response object
