ios - 如何向 firebase 添加新项目

Question

我想向我的列表添加一个新项目，我使用 firebase，但没有用户(电子邮件、密码)

我想添加这样的新项目:-

list
-vdjs43ndjufd87
         "name" : Jak
         "university" : Harvard



list
-vdjs43ndjufd87
          "name" : Jak
          "university" : Harvard
          "age" : 23

此代码不适用于我:-

let key = ref.child("posts").childByAutoId().key

let post = ["uid": userID,
        "author": username,
        "title": title,
        "body": body]
let childUpdates = ["/posts/\(key)": post,
                "/user-posts/\(userID)/\(key)/": post]
ref.updateChildValues(childUpdates)`h

Answer 1

您需要做的就是:

let post = ["uid": userID,
    "author": username,
    "title": title,
    "body": body]  

ref.child("posts").childByAutoId().setValue(post)
