我正在使用Swift和Firebase开发iOS应用程序。
我正在尝试让用户使用单独的按钮更改其电子邮件和密码以及存储在同一 View Controller 中firebase中的其余信息。
这是一个来自仪表板的用户的示例:
{
"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/"
}
}
}
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,

"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,

]
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.ref.childByAppendingPath("Users").childByAppendingPath(self.ref.authData.uid).updateChildValues(newUser)
self.navigationController?.popViewControllerAnimated(true)
}
}
在每个按钮中，我将更新Firebase中的整个词典!哪有错
如何在Firebase中仅更新“电子邮件”按钮中的电子邮件值，
和提供者在密码按钮？
最佳答案
评论中的这个问题和答案帮助了我。由于没有官方回答的问题，我将添加一个更新的代码，因为不赞成使用注释中的一个。
ref.child("yourKey").child("yourKey").updateChildValues(["yourKey": yourValue])
这对我来说非常有效。
关于ios - 在Firebase中更新字典中的单个值-Swift Project，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/36955973/
