如何在Firebase中向用户发送验证邮件之前注销用户

Question

创建新用户时，我需要注销他们，然后发送验证电子邮件，以确保他们拥有电子邮件地址。目前，我的代码创建用户并执行“sendEmailVerification”调用，但保持用户登录。如何注销我的用户并检查他们是否验证了电子邮件？

func signUp(with email: String, password: String, firstName: String, lastName: String) {
    self.presentActivityView()
    Auth.auth().createUser(withEmail: email, password: password) {[unowned self] (user, error) in
        DispatchQueue.main.async { [unowned self] in
            self.dismissActivityView()
            if let err = error {
                self.addAlertController(title: "Error!", message: err.localizedDescription)
            } else {
                let changeReq = Auth.auth().currentUser?.createProfileChangeRequest()
                changeReq?.displayName = firstName + " " + lastName
                if let url = self.profilePicURLString {
                    changeReq?.photoURL = URL(string: url)
                }
                changeReq?.commitChanges(completion: { (error) in
                    if error == nil {
                        //Profile updated successfully
                    }else {
                        //Profile not updated successfully
                    }
                })
                Auth.auth().currentUser?.sendEmailVerification(completion: { (error) in
                    if error == nil {
                        //Verification initiated successfully
                    }else {
                        print("Error: \(error)")
                    }
                })
                let vc = MainStoryboard.instantiateViewController(withIdentifier: "SNStoryFeedController") as! SNStoryFeedController
                let nc = UINavigationController(rootViewController: vc)
                UIApplication.shared.keyWindow?.rootViewController = nc
            }
        }
    }
}

您唯一应该做的就是从您自己的应用程序中注销：

// for FIRAuth
try? Auth.auth()?.signOut()

// for GoogleSignIn
GIDSignIn.sharedInstance().signOut()

safari部分由系统处理，你不需要担心。
