在 Firebase 身份验证中更新电话号码 - Swift

Question

Is there a way to update the phone number in firebase auth? The thing is if the user entered a wrong number in registration then can I update the old number to new one then send the verification code in that new number? How can I achieve this?

Answer 1

There is a method on the User object called updatePhoneNumber , which seems to be what you want.

The documentation doesn't mention anything about what this does to the verification status, although I'd assume it indeed will require the new number to be verified too. Give it a try, and let me know if that isn't the case.

Answer 2

You're welcome

Auth.auth().currentUser?.updatePhoneNumber(credential, completion: { (error) in
            if error == nil {
                print("succes")
            }
        })

On the screen where the user has to enter their phone number:

var verificationId: String?

PhoneAuthProvider.provider().verifyPhoneNumber(phoneNumberTextField.text!, uiDelegate: nil) { (verificationID, error) in

    if let error = error { return }

    self.verificationId = verificationID else { return }
}

On the screen where the user has to enter the sms verification code:

let credential = PhoneAuthProvider.provider().credential(withVerificationID: self.verificationId!, verificationCode: smsTextField.text!)

Auth.auth().currentUser?.updatePhoneNumber(credential, completion: { (error) in

    if let error = error { return }
})
