ios - 如何修复将用户输入发送到用户个人资料下的 Firebase 数据库的问题？

Question

因此，假设用户注册已完成(此代码已经正确)，下一个窗口要求用户输入个人信息(教育等)，您如何编写代码将此信息发送到用户个人资料下的 Firebase。

我已经完成注册页面，并且在那里创建的用户已经转到 firebase。

这是我注册后的页面。没有错误，但显然不完整。

import UIKit
import Firebase
import CoreFoundation
import AVFoundation
import SwiftKeychainWrapper
import FirebaseDatabase

class FeedVC: UITableViewController {

    override func viewDidLoad() {

navigationItem.leftBarButtonItem = UIBarButtonItem(title: "Sign Out", style: .plain, target: self, action: #selector(signOut))

        super.viewDidLoad()


        // Uncomment the following line to preserve selection between presentations
        // self.clearsSelectionOnViewWillAppear = false

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
        // self.navigationItem.rightBarButtonItem = self.editButtonItem

        post()

    }


    //override func didReceiveMemoryWarning() {
       // super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
   // }


    // MARK: - Table view data source

    //override func numberOfSections(in tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        //return 1
   // }

   // override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
        //return 5
  // }

    //override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
       // return UITableViewCell()
    //}



func post() {


            let MainFunInterest = "MainFunInterest"
            let SomethingInterestingIhaveRead = "SomethingInterestingIhaveRead"
            let JobOrEducation = "JobOrEducation"
            let WhatIamConsideringBuying = "WhatIamConsideringBuying"

            let post : [String : AnyObject] = ["MainFunInterest" : MainFunInterest as AnyObject,
                                               "SomethingInterestingIhaveRead" : SomethingInterestingIhaveRead as AnyObject,
                                               "JobOrEducation" : JobOrEducation as AnyObject,
                                               "WhatIamConsideringBuying" : WhatIamConsideringBuying as AnyObject]

                let databaseRef = Database.database().reference()
                databaseRef.child("personal info").childByAutoId().setValue(post)

    }



    @objc func signOut (_sender: AnyObject) {



        KeychainWrapper.standard.removeObject(forKey: "uid")
        do {
            try Auth.auth().signOut()
        } catch let signOutError as NSError {
            print ("Error signing out: %@", signOutError)
        }

        dismiss(animated: true, completion: nil)

        }

}

我可以退出该页面。当我当前注册时，进入 firebase 的只是用户应输入的股票描述(例如“教育”在 firebase 中注册，而不是用户应输入的内容。

我看到您使用 FirebaseDatabase，但我忘记了这是否是新的 FirebaseFirestore。无论如何，在这种情况下，您要么需要阅读更多与 firebase 数据库相关的文档来创建自己的数据库查询，要么需要先从“education”读取数据，然后编写自己的写入、更新、删除方法来处理数据更改重新发布或更新它们。希望有帮助!
