ios - 将新子项添加到 Firebase 数据库

Question

尝试向新子项添加个人资料图像字符串。我尝试了 setvalue 但它将 uid 中的所有子项更改为仅配置文件图像。

if let data = try? Data.init(contentsOf: dataurl!){
    let image: UIImage = UIImage(data: data)!
    self.userProfileImage.image = image
    self.userProfileImage.reloadInputViews()
    self.activityloading.stopAnimating()
    // Test Database Ref
    let stringURL = dataurl?.absoluteString

    let databaseRef = Database.database().reference().child("users").child(currentID!)
    let userImageElement: [String: Any] = ["profileimage" : stringURL!]
    databaseRef.observe(.childAdded, with: { (DataSnapshot) in
        var dictionary = DataSnapshot.value as! [String : Any]
        dictionary = userImageElement
    })

Answer 1

将 databaseRef.observe(.childAdded, with:{}) 替换为 databaseRef.updateChildValues(userImageElement) 。
