ios - Swift Firebase 在应用程序终止时删除用户

Question

我试图在应用程序终止时删除用户，但这不起作用。如果我有一个匿名用户登录并且用户关闭了应用程序，我不希望 firebase 保存匿名用户。我想删除它。这是我当前的代码。提前谢谢你

func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
        if let users = Auth.auth().currentUser {
            if !users.isAnonymous {
              return
            }else {
                users.delete(completion: { (error) in
                    if error != nil {
                        print(error!)
                        return
                    }
                    try! Auth.auth().signOut()
                    print("Anonymous user deleted")
                })
            }
        }
    }

Answer 1

我将 ViewDidLoad 中的监听器添加到我希望从中删除用户的屏幕。像这样:

    NotificationCenter.default.addObserver(self, selector: #selector(suspending), name: NSNotification.Name.UIApplicationWillResignActive, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(suspending), name: NSNotification.Name.UIApplicationWillTerminate, object: nil)

然后我有这个功能来删除用户:

  @objc func suspending () {
    if Auth.auth().currentUser != nil {
        let user = Auth.auth().currentUser
        user?.delete { error in
            if let error = error {
                print("An error happened delting the user.")
            } else {
                print("Account succesfully deleted.")
            }
        }
    }
}

唯一可能发生的事情是，您需要重新进行身份验证。如果是这种情况，请遵循 this answer实现它也是如此
