ios - 如何在firebase中更新当前用户电子邮件和密码(在用户节点和身份验证中)？
<p><p>我正在尝试更新我的用户详细信息页面(用户名、电话号码、电子邮件和密码)。无法更新电子邮件字段，以防它被更新意味着不在两者中(用户和身份验证)。任何 hlp 将不胜感激。 swift2.2中的.plz代码</p>
<p>这里是我的 <em>userDetilsViewController</em> </p>
<pre><code>class UserDetailsViewController: UIViewController {
var user:UserDetails?
let userRegister = UserInfo()
var user_name:String?
var first_name:String?
var last_name:String?
var ph_no:String?
var e_mail:String?
var pass_word:String?
var activeField: UITextField?
@IBOutlet var Username: UITextField!
@IBOutlet var Firstname: UITextField!
@IBOutlet var Lastname: UITextField!
@IBOutlet var email: UITextField!
@IBOutlet var phNo: UITextField!
@IBOutlet var password: UITextField!
var rootRef: FIRDatabaseReference! {
return FIRDatabase.database().reference()
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(true)
let userRef = FIRDatabase.database().reference().child("users")
userRef.observeEventType(.Value, withBlock: { (snapshot)in
for userInfo in snapshot.children {
self.user = UserDetails(snapshot: userInfo as! FIRDataSnapshot)
print(self.user)
}
if let user = self.user{
self.Username.text = user.username
self.Firstname.text = user.firstname
self.Lastname.text = user.lastname
self.email.text = user.email
self.phNo.text = user.phno
}
})
self.navigationController?.popViewControllerAnimated(true)
}
@IBAction func reset(sender: AnyObject) {
let userRef = FIRDatabase.database().reference().child("users")
if Username.text == "" {
Username.text = "enter title"
} else {
user_name = Username.text
}
if Firstname.text == ""{
Firstname.text = "Firstname Missing"
} else {
first_name = Firstname.text
}
if Lastname.text == "" {
Lastname.text = "Lastname Missing"
} else {
last_name = Lastname.text
}
if phNo.text == "" {
phNo.text = "Phno Missing"
} else {
ph_no = phNo.text
}
if email.text == "" {
email.text = "email Missing"
} else {
if let user = FIRAuth.auth()?.currentUser {
user.updateEmail(email.text!, completion: { (error) in
if let error = error{
print(error.localizedDescription)
} else {
let alertView = UIAlertView(title: "Update Email", message: "email Updated", delegate: self, cancelButtonTitle: "Ok")
alertView.show()
}
})
self.e_mail = self.email.text
print(self.e_mail)
}
}
let updatenote = UserDetails(username: user_name!, firstname: first_name!, lastname: last_name!, email: e_mail!, phno: ph_no!)
print(updatenote)
let key = user!.ref!.key
print(key)
let updateRef = rootRef.child("/users/\(key)")
updateRef.updateChildValues(updatenote.toAnyObject())
navigationController?.popViewControllerAnimated(true)
}
</code></pre></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我认为问题出在以下几行:</p>
<pre><code>if let user = FIRAuth.auth()?.currentUser {
user.updateEmail(email.text!, completion: { (error) in
</code></pre>
<p>“用户”是当前用户的副本，而不是对当前用户的引用，因此当您更新用户时，您并没有更新实际的当前用户。</p>
<p>尝试使用此代码更新用户电子邮件地址 - 还要记住，要更新电子邮件，用户必须最近登录。即您必须以用户身份登录才能更改电子邮件。</p>
<pre><code>FIRAuth.auth()?.currentUser?.updateEmail(email.text!) { (error) in
// ...
}
</code></pre>
<p>请注意，我可能完全错了......</p></p>
