当与其他用户登录时，它仍然会从任何地方选择以前的用户uuid

Question

我正在处理我的一些项目，我面临的问题是当我使用用户"A"登录并使用该应用程序一段时间时，我注销用户，然后我使用另一个用户"B"登录，然后在一些屏幕中，我必须显示用户配置文件图片(Baseurl + 配置文件图片名称(。它没有显示，当我记录个人资料图片网址时，我发现它仍然拾取旧登录用户"A"的uuid。

注意 ：- BaseUrl 由与 uuid 的串联组成。

这是我用来保存登录响应数据并在注销响应时为零数据的登录和注销方法类和常量类

如果状态为 1，则登录方法：-

                        if(status == 1)
                        {
                            DispatchQueue.main.async {
                                GAReusableClass.sharedInstance.hideActivityIndicator()
                                UserDefaults.standard.set(self.DataDict, forKey:MaindataKey)
                                let Dict = self.mainDict[KData] as!  [String: AnyObject]
                                print("self.DataDict", self.DataDict)
                                let User_ID = Dict[KUuid]as! String
                                print(User_ID)
                                let HMACSECRETKEY = self.deviceToken + "+" + User_ID
                                kHMACKey = HMACSECRETKEY
                                let cipher:String = CryptoHelper.encrypt(input:HMACSECRETKEY)!;
                                print(HMACSECRETKEY)
                                UserDefaults.standard.setValue(cipher, forKey:HmacKey)
                                UserDefaults.standard.set(true, forKey: "isLogin")
                                GAloginUserInfo.shared.saveUserInfo(dict: Dict )
                                let tabar = self.storyboard?.instantiateViewController(withIdentifier: "GAtHomeTabbarViewController") as! GAtHomeTabbarViewController
                                self.navigationController?.pushViewController(tabar, animated: true)
                            }

如果状态为 1，则注销方法 ：-

                    if(status == 1)
                    {
                        DispatchQueue.main.async {
                            GAReusableClass.sharedInstance.hideActivityIndicator()
                            defaults.removeObject(forKey: MaindataKey)
                            defaults.removeObject(forKey: HmacKey)
                            defaults.set(false, forKey: "isLogin")
                            GAloginUserInfo.shared.removeUserInfo()

                            let login = self.storyboard?.instantiateViewController(withIdentifier: "GALoginViewController") as! GALoginViewController
                            self.navigationController?.pushViewController(login, animated: true)
                        }

常量类：-

var kHMACKey = String()
let Headerkey = "header"
let KData = "data"
let KStatus = "status"

我认为当您注销UIKit时会保留一些值，以删除它，注销时，应清除所有视图控制器，以便删除所有UIKit数据并解决问题。如果您的注销 API 状态为 1，请输入此代码。

let toViewController = mainStoryboard.instantiateViewController(withIdentifier: "KSLoginViewController") as! KSLoginViewController// Login view controller here
                                    let fromView = UIApplication.shared.keyWindow!.rootViewController!.view
                                    UIApplication.shared.keyWindow?.rootViewController = toViewController
                                    
                                    let toView = toViewController.view
                                    toView?.addSubview(fromView!)
                                    
                                    UIView.animate(withDuration: 0.38, delay: 0.2, options: [], animations: {
                                        fromView?.transform = CGAffineTransform(translationX: -UIScreen.main.bounds.width, y: 0)
                                    }, completion: { finished in
                                        fromView?.removeFromSuperview()
                                    })

注销后，

当您登录后尝试推送另一个视图控制器时，请使用此代码。

let teacher = studentStoryboard.instantiateViewController(withIdentifier: "KSStudentDashboardVC") as! KSStudentDashboardVC
                                        let aObjNavi = UINavigationController(rootViewController: teacher)
                                        let appDelegate: AppDelegate = (UIApplication.shared.delegate as? AppDelegate)!
                                        appDelegate.window?.rootViewController = aObjNavi

我认为

问题是由于线程引起的。从主调度队列中移动非 uikit 类操作。

如果状态为 1，则登录方法：-

if(status == 1)
    {
        UserDefaults.standard.set(self.DataDict, forKey:MaindataKey)
        let Dict = self.mainDict[KData] as!  [String: AnyObject]
        print("self.DataDict", self.DataDict)
        let User_ID = Dict[KUuid]as! String
        print(User_ID)
        let HMACSECRETKEY = self.deviceToken + "+" + User_ID
        kHMACKey = HMACSECRETKEY
        let cipher:String = CryptoHelper.encrypt(input:HMACSECRETKEY)!;
        print(HMACSECRETKEY)
        UserDefaults.standard.setValue(cipher, forKey:HmacKey)
        UserDefaults.standard.set(true, forKey: "isLogin")
        GAloginUserInfo.shared.saveUserInfo(dict: Dict )

        DispatchQueue.main.async {
            GAReusableClass.sharedInstance.hideActivityIndicator()
            let tabar = self.storyboard?.instantiateViewController(withIdentifier: "GAtHomeTabbarViewController") as! GAtHomeTabbarViewController
            self.navigationController?.pushViewController(tabar, animated: true)
        }
    }

如果状态为 1，则注销方法 ：-

if(status == 1)
    {
        defaults.removeObject(forKey: MaindataKey)
        defaults.removeObject(forKey: HmacKey)
        defaults.set(false, forKey: "isLogin")
        GAloginUserInfo.shared.removeUserInfo()
        DispatchQueue.main.async {
            GAReusableClass.sharedInstance.hideActivityIndicator()
            let login = self.storyboard?.instantiateViewController(withIdentifier: "GALoginViewController") as! GALoginViewController
            self.navigationController?.pushViewController(login, animated: true)
        }
    }
