During resistration of a user, i am uploading some photoes to the server. The first one is the profile photo. And the rest photoes i want to upload after the resistration process once completed. Means i want to upload the photo after getting the userid and the access token.Means after a successfully image upload, the user will enter to the "matchesViewController" and then only the upload process will start. Also i want to upload these photoes in background thread. Also if the app rinning in background then also the upload process should be continue. All the uploading process is done by Alamofire.
By writting the following code the photos are uploading successfully, but it is taking more time. Which is not a good user experience.
Also please tell me how to continue the upload process when the app running in back ground thread.
Also if the code is not good please help me to modify any changes in code if needed.
My code is: -
private func handleRegistration (_ parameterDict : [String : Any]){
let url = USER_REGISTER_URL
let headers: HTTPHeaders = [
"Content-Type": "application/x-www-form-urlencoded"
]
Alamofire.upload(multipartFormData: { (multipartFormData) in
for (key, value) in parameterDict {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String)
}
let random = randomString(length: 7)
multipartFormData.append(self.selectedProfilePic.image!.jpegData(compressionQuality: 0.4)!, withName: "fileset",fileName: "\(random).jpg", mimeType: "image/jpg")
}, usingThreshold: UInt64.init(), to: url, method: .post, headers: headers) { (result) in
switch result{
case .success(let upload, _, _):
upload.responseJSON { response in
print(response)
var userId: String?
var token: String?
if let result = response.result.value {
let JSON = result as! NSDictionary
guard let accessToken = JSON["access_token"] as? String
else{ return }
guard let uid = JSON["User_Id"] as? String
else{return}
userId = uid
token = "bearer " + accessToken
UserDefaults.standard.set(Int(uid), forKey: "User_Id")
UserDefaults.standard.set(token, forKey: "access_token")
let phone = JSON["Phone_Number"] as? String
let FirstName = JSON["FirstName"] as? String
let email = uid + "@gmail.com"
let tempDictionary : Dictionary = [kFIRSTNAME : FirstName!, kLASTNAME : "", kFULLNAME : FirstName!, kPHONE : phone!, kREGISTERUSEID: userId, kEMAIL: email] as [String : Any]
self.checkDeviceTokenAvailibility(uid: Int(userId!)!)
self.startRegistrationWithFirebase( detailDict: tempDictionary)
let storyBoard = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "MainTabbarView")
storyBoard.modalPresentationStyle = .fullScreen
self.present(storyBoard, animated: true, completion: nil)
if let message = JSON["Message"] as? String{
if message == "Please Upload a image."{
}
}
}
if userId != nil && token != nil{
self.multiImageUpload(userId: Int(userId!)!, token: token!)
}
print("Succesfully uploaded")
if let err = response.error{
// onError?(err)
// print(err.localizedDescription)
return
}
// onCompletion?(nil)
}
case .failure(let error):
print("Error in upload: \(error.localizedDescription)")
// onError?(error)
}
}
}
