注册成功后，我在LoginViewController. 我将 UID 保存在LoginViewController. 我正在检索 UID RegistrationViewController。但在这里我得到nil所有人为什么？
请在代码中帮助我。
将 UID 保存在LoginViewController：
func logInService(){
let parameters = ["username":Int(userIdTextFielf.text ?? "") as Any,
"imei_number":"",
"password":passwordTextField.text as Any,
"name":"name"]
let url = URL(string: "https://dev.com/webservices/login")
var req = URLRequest(url: url!)
req.httpMethod = "POST"
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters as Any, options: .prettyPrinted) else {return}
req.httpBody = httpBody
let session = URLSession.shared
session.dataTask(with: req, completionHandler: {(data, response, error) in
if response != nil {
// print(response)
}
if let data = data {
do{
let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [String: Any]
print("the json of loginnnnnn \(json)")
self.Uid = json["id"] as? Int
let emailL = json["user_email"] as? String
KeychainWrapper.standard.set(emailL ?? "", forKey: "user_email")
KeychainWrapper.standard.set(self.Uid!, forKey: "Uid")
let saveUserId: Bool = KeychainWrapper.standard.set(self.Uid!, forKey: "Uid")
DispatchQueue.main.async {
let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
let navigationController = mainStoryBoard.instantiateViewController(withIdentifier: "HomeNavigation")
let appDelagate = UIApplication.shared.delegate
appDelagate?.window??.rootViewController = navigationController
}
}catch{
print("error")
}
}
}).resume()
}
检索 UID RegistrationViewController：
@IBAction func registerButton(_ sender: Any) {
if (nameTextField.text == "" || phoneNumTextField.text == "" || passwordTextField.text == "" || conformPasswordTextField.text == "")
{
registerButton.isHidden = false
sendOtpButton.isHidden = true
AlertFun.ShowAlert(title: "Title", message: "RequiredAllFields", in: self)
}
else{
registerButton.isHidden = true
sendOtpButton.isHidden = false
otpTextField.isHidden = false
resendButn.isHidden = false
DispatchQueue.main.async {
self.otpTextField.text = self.otpField as? String
}
registerService()
otpTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(update), userInfo: nil, repeats: true)
}
}
@IBAction func sendOTPButton(_ sender: Any) {
otpService()
}
//MARK:- Service part
@objc func registerService()
{
print("register tapped")
let parameters = ["mobile_number": Int(phoneNumTextField.text ?? "") as Any,
"email":emailTextField.text as Any,
"password":passwordTextField.text as Any,
"name": nameTextField.text as Any]
let url = URL(string: "https://dev.anyemi.com/webservices/anyemi/register")
var req = URLRequest(url: url!)
req.httpMethod = "POST"
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) else {return}
req.httpBody = httpBody
let session = URLSession.shared
session.dataTask(with: req, completionHandler: {(data, response, error) in
if response != nil {
// print(response)
}
if let data = data {
do{
let userId: Int? = KeychainWrapper.standard.integer(forKey: "Uid")
print("login userid \(userId)")
if userId != nil{
AlertFun.ShowAlert(title: "Title", message: "user exist", in: self)
}
else{
let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [String: Any]
print("the json regggggggggggis \(json)")
let phNum = json["mobile_number"] as? Int
let status = json["status"] as? String
self.otpField = json["otp"] as? Int
}
}catch{
print("error")
}
}
}).resume()
}
@objc func otpService(){
let parameters = ["mobile_number": phoneNumTextField.text as Any,
"otp": otpTextField.text as Any]
let url = URL(string: "https://dev.com/webservices/otpverify")
var req = URLRequest(url: url!)
req.httpMethod = "POST"
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) else {return}
req.httpBody = httpBody
let session = URLSession.shared
session.dataTask(with: req, completionHandler: {(data, response, error) in
if response != nil {
// print(response)
}
if let data = data {
do{
let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [String: Any]
print("the json of otppppppppp \(json)")
DispatchQueue.main.async {
if (self.otpTextField.text == String(self.otpField ?? 12)){
print("registration successfullllll...")
let mobileNum = json["mobile_number"] as! [String : Any]
//self.Uid = mobileNum["id"] as? String
let name = mobileNum["name"] as? String
let phNum = mobileNum["username"] as? String
print("otp name \(String(describing: name))")
print("otp phnumber \(String(describing: phNum))")
let loginVC = self.storyboard?.instantiateViewController(withIdentifier: "LoginViewController") as! LoginViewController
self.present(loginVC, animated: true)
}
else if self.otpTextField.text == ""{
AlertFun.ShowAlert(title: "", message: "Please enter OTP", in: self)
print("register fail")
}
else {
AlertFun.ShowAlert(title: "", message: "Invalid OTP", in: self)
print("register fail")
}
}
}catch{
print("error")
}
}
}).resume()
}
}
一直以来我都打算分开，为什么？我在哪里做错了。
