I'm working on iOS application using swift and firebase. I'm trying to let the user change his email and password and the rest of his information stored in firebase in the same view controller using separate buttons.
我正在使用swift和firebase开发iOS应用程序。我试着让用户使用不同的按钮来更改他的电子邮件和密码，以及在同一个视图控制器中存储在firebase中的其余信息。
Here's example of one user from the dashboard:
下面是一个来自仪表板的用户示例:
{
"Users" : {
"08e5443c-cdde-4fda-8733-8c4fce75dd34" : {
"BusinessName" : "looliCake",
"Category" : "Cooking",
"City" : "Riyadh",
"ContactMe" : "05551233210",
"Details" : "many flaiver choose",
"Email" : "loolicack@gmail.com",
"PhoneNumber" : "05551233210",
"Provider" : "123",
"ShortDescription" : "best pop cake ever . ",
"Website1" : "www.looliCack.com",
"Website2" : "https://www.instagram.com/loolicack/"
}
}
}
Here's the code:
这是代码:
let mainpass = NSUserDefaults.standardUserDefaults().objectForKey("password") as? String
let mainEmail = NSUserDefaults.standardUserDefaults().objectForKey("Email") as? String
@IBAction func EditEmail(sender: AnyObject) {
if EmailAddressTF.text==""
{
let alert = UIAlertController(title: "Oops!", message:"Make sure to fill in all required textfields", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
}
else
{
let isEqu = (mainEmail == self.EmailAddressTF.text)
if(isEqu == true) {
} else {
let ref = Firebase(url: "https://businesswallet.firebaseio.com/")
ref.changeEmailForUser(mainEmail, password: mainpass, toNewEmail: self.EmailAddressTF.text, withCompletionBlock: { error in
if error != nil {
if let errorCode = FAuthenticationError(rawValue: error.code) {
switch (errorCode) {
case .EmailTaken:
print("Email taken")
let alert = UIAlertController(title: "Oops!", message:"Sorry,Email taken", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
case .InvalidEmail:
print("invalid email")
let alert = UIAlertController(title: "Oops!", message:"invalid email", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
case .NetworkError:
print("Network Error")
let alert = UIAlertController(title: "Oops!", message:"Network error, check your connection", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
default:
print("Unknown Error")
let alert = UIAlertController(title: "Oops!", message:"Unknown Error", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
}
}
} else {
NSUserDefaults.standardUserDefaults().setValue(self.EmailAddressTF.text, forKey: "Email")
print("Email changed successfully")
let newUser = [
"Provider": self.PasswordTF.text!,
"Email": self.EmailAddressTF.text,
"BusinessName": self.BusinessNameTF.text ,
"ShortDescription" : self.ShortDescriptionTF.text,
"Category" : self.itemSelected,
"City" : self.CityTF.text,
"ContactMe" : self.ContactMeTF.text,
"PhoneNumber" : self.PhoneNumberTF.text,
"Website1": self.Website1TF.text,
"Website2": self.Website2TF.text,
"Details": self.DetailsTV.text
]
self.ref.childByAppendingPath("Users").childByAppendingPath(self.ref.authData.uid).updateChildValues(newUser)
self.navigationController?.popViewControllerAnimated(true)
}
})
} //Big Else
}
} //EditEmailButton
@IBAction func EditPassword(sender: AnyObject) {
if PasswordTF.text==""
{
let alert = UIAlertController(title: "Oops!", message:"Make sure to fill in all required textfields", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
}
else
{
if RepasswordTF.text != PasswordTF.text
{
let alert = UIAlertController(title: "Oops!", message:"You Entered Different Passwords", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
}
else {
ref.changePasswordForUser( NSUserDefaults.standardUserDefaults().objectForKey("Email") as? String, fromOld: NSUserDefaults.standardUserDefaults().objectForKey("password") as? String, toNew: self.PasswordTF.text)
{
(ErrorType) -> Void in
if ErrorType != nil {
print(ErrorType)
print("There was an error processing the request")
}
else
{
NSUserDefaults.standardUserDefaults().setValue(self.PasswordTF.text, forKey: "password")
print("Password changed successfully")
}
}
let newUser = [
"Provider": self.PasswordTF.text!,
"Email": self.EmailAddressTF.text,
"BusinessName": self.BusinessNameTF.text ,
"ShortDescription" : self.ShortDescriptionTF.text,
"Category" : self.itemSelected,

]
self.ref.childByAppendingPath("Users").childByAppendingPath(self.ref.authData.uid).updateChildValues(newUser)
self.navigationController?.popViewControllerAnimated(true)
}
} //else
}
@IBAction func EditBusinessInfo(sender: AnyObject) {
if BusinessNameTF.text==""
{
let alert = UIAlertController(title: "Oops!", message:"Make sure to fill in all required textfields", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
}
else
{
let newUser = [
"Provider": self.PasswordTF.text!,
"Email": self.EmailAddressTF.text,
"BusinessName": self.BusinessNameTF.text ,
"ShortDescription" : self.ShortDescriptionTF.text,
"Category" : self.itemSelected,
"City" : self.CityTF.text,
"ContactMe" : self.ContactMeTF.text,
"PhoneNumber" : self.PhoneNumberTF.text,
"Website1": self.Website1TF.text,
"Website2": self.Website2TF.text,
"Details": self.DetailsTV.text
]
self.ref.childByAppendingPath("Users").childByAppendingPath(self.ref.authData.uid).updateChildValues(newUser)
self.navigationController?.popViewControllerAnimated(true)
}
}
In each button, I'm updating the entire dictionary in firebase! Which's wrong!
在每个按钮中，我将在firebase中更新整个字典!这是错的!
How can I update in firebase only the email value in email button, and provider in password button?
如何在firebase中只更新电子邮件按钮中的电子邮件值，如何在密码按钮中更新提供者?

This question and answer in the comments helped me out. Since there isn't an official answered question, I will add one with updated code cause the one in the comments is deprecated.
在评论中这个问题和答案帮助了我。由于没有正式回答的问题，我将添加一个带有更新代码的问题，因为注释中的问题已被弃用。
ref.child("yourKey").child("yourKey").updateChildValues(["yourKey": yourValue])
This worked perfectly for me.
这对我来说非常有效。

you can simply navigate to that single value which you want to update then use setValue(and here give it the value) here is a very simple example :
您可以简单地导航到您想要更新的那个值，然后使用setValue(这里给出它的值)这里有一个非常简单的例子:
var key : FIRDatabaseReference!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
addData()
}
func addData()
{
var data :Dictionary<String,Any> = ["name":"nawal","id":123]
key = DBprovider.instance.DBRef.child("Data").childByAutoId()
key.setValue(data)
}
//add a button name it update or whatEver and connect it as Action
//添加一个更新的按钮名或其他，并将其连接为动作
@IBAction func updateData(_ sender: Any) {
DBprovider.instance.DBRef.child("Data").child(key.key).child("id").setValue(111)
}

let path1 = FirebaseBaseUrl + "users/" + id
let chilRef1 = FIRDatabase.database().referenceFromURL(path1)
// chilRef1.updateChildValues(["status": "online"])
chilRef1.updateChildValues(["status": "offline"]) { (error, ref) in
if(error != nil){
print("Error",error)
}else{
print("\n\n\n\n\nYou are Offline...")
}
}
