如何在使用 Alamofire 时将令牌存储在 NSUserDefault 中

Question

我正在使用OTP进行电子邮件验证。我使用了两个API，一个用于注册，另一个用于OTP验证。我想在用户有效时移动到下一页。为此，我想使用 NSUserDefault 来存储来自 API 响应的令牌。当，我使用这个时，我无法存储这个。请有人帮我。这是我的代码

class OTPVerification: UIViewController, UITextFieldDelegate {
@IBOutlet weak var tfReceivedOTP: UITextField!
var datapassed:String!
let loader = MFLoader()
override func viewDidLoad() {
  super.viewDidLoad()
  tfReceivedOTP.attributedPlaceholder =     NSAttributedString(string:"OTP",
                                                           attributes:[NSForegroundColorAttributeName: UIColor.whiteColor()])
  tfReceivedOTP.delegate = self
  print(datapassed)
}


override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(true)
    let defaults = NSUserDefaults.standardUserDefaults()
    if defaults.objectForKey("email") == nil {
        if let loginController = self.storyboard?.instantiateViewControllerWithIdentifier("ConfirmationMassage") as? SignInConformation {
            self.navigationController?.presentViewController(loginController, animated: true, completion: nil)
        }
    }
 let defaults = NSUserDefaults.standardUserDefaults()
 if defaults.objectForKey("token") == nil {
 if let loginController = self.storyboard?.instantiateViewControllerWithIdentifier("ConfirmationMassage") as? SignInConformation {
 self.navigationController?.presentViewController(loginController, animated: true, completion: nil)
   }
 }

}

func textFieldShouldReturn(textField: UITextField) -> Bool {
    textField.resignFirstResponder()
    return true
}
override func prefersStatusBarHidden() -> Bool {
    return true
}
@IBAction func btnOTPVerificationTapped(sender: AnyObject) {
    loader.showActivityIndicator(self.view)
    let rgModel = CAOTPVerify()
    rgModel.email = datapassed!
    rgModel.otpPassword = tfReceivedOTP.text!
    rgModel.otpRegister({(Void, Any) -> Void in
        let defaults = NSUserDefaults.standardUserDefaults()
        if let name = defaults.stringForKey("userNameKey") {
            print("(name )hjhjkhkhkh")
        }
        self.loader.hideActivityIndicator(self.view)
        if let response = Any as? [String : AnyObject] {
            //print(response)
            if let messgae = response["message"] as? String {
                let alert = UIAlertController(title: "Alert", message: messgae, preferredStyle: UIAlertControllerStyle.Alert)
                alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: {action in
                      let storyboard = UIStoryboard(name: "Main", bundle: nil)
                      let OPTView = storyboard.instantiateViewControllerWithIdentifier("sideBarMenu") as! SideBarMenu
                      self.navigationController!.pushViewController(OPTView, animated: true)
                }))
                self.presentViewController(alert, animated: true, completion: nil)
            }
        }
        }, errorCallback: {(Void, NSError) -> Void in
            self.loader.hideActivityIndicator(self.view)
    })    
}

您没有发布将字符串保存到NSUserDefaults的代码。您可以参考以下代码将字符串保存在NSUserDefaults

let myString = "Hello World"
NSUserDefaults.standardUserDefaults().setObject(myString, forKey: "myKey")
