如何使用Swift在Firebase中存储自定义对象? [英] How to store custom object in Firebase with Swift?

问题描述

我正在移植一个android应用程序，并在android中使用firebase，因此可以通过这种方式保存格式.我该如何在Swift上执行此操作?我读到我只能存储这种数据

I'm porting an android app and using firebase in android it is possible to save a format in this way. How can i do this on Swift? I read that i can store only this kind of data

• NSString
• NSNumber
• NSDictionary
• NSArray

如何在原子操作中存储obj?将用户对象的每个字段存储在单独的操作中是正确的吗?

How can I store the obj in atomic operation? It's correct to store every field of the user object in separate action?

Android上的Firebase

Firebase on Android

mDatabaseReferences.child("users").child(user.getUuid()).setValue(user)

推荐答案

我通常将对象作为字典存储在Firebase上.如果在我的应用程序中有一个User对象，并且它具有如下属性:

I generally store objects as dictionaries on firebase. If, within my application, I have a User object, and it has properties as such:

class User {
var username = ""
var email = ""
var userID = ""
var consecutiveDaysLoggedOn = Int()
}



let newUser = User()
   newUser.username = "LeviYoder"
   newUser.email = "[e-mail]"
   newUser.userID = "L735F802847A-"
   newUser.consecutiveDaysLoggedOn = 1

我只是将这些属性存储为字典，然后将该字典写入我的Firebase数据库:

I would just store those properties as a dictionary, and write that dictionary to my firebase database:

let userInfoDictionary = ["username" : newUser.username
                           "email" : newUser.email
                           "userID" : newUser.userID
              "consecutiveDaysLoggedOn" : newUser.consecutiveDaysLoggedOn]

let ref = Database.database().reference.child("UserInfo").child("SpecificUserFolder")
//      ref.setValue(userInfoDictionary) { (error:Error?, ref:DatabaseReference) in

ref.setValue(userInfoDictionary, withCompletionBlock: { err, ref in
    if let error = err {
        print("userInfoDictionary was not saved: \(error.localizedDescription)")
    } else {
        print("userInfoDictionary saved successfully!")
    }
}

这能解决您的问题吗?
