使用swift 3 firebase（所有字段）更新数据 - XCODE 8（2017）

Question

我对这个问题进行了很多努力，所以我会提供答案以防其他人遇到问题

Answer 1

swift似乎更新它的节点是通过＆＃34;替换并添加＆＃34; firebase网站的例子似乎没有用，所以我通过反复试验弄明白了

覆盖func viewDidLoad（）{         super.viewDidLoad（）

    self.txtBankName.text = oBank.BankName;
    self.txtBankType.text = oBank.BankType;
    self.txtBankBalance.text = String(describing: oBank.BankBalance!)
    fireBaseKey = oBank.fireBaseKey;
    lblFireBaseKey.text = fireBaseKey;

    refBanks  = Database.database().reference().child("Bank")

}

func updateBankFirebase()
{
    let key = oBank.fireBaseKey
    let bankBalance:String? = self.txtBankBalance.text;
    let updateBank = ["BankName":oBank.BankName!,"BankType":self.txtBankType.text!,"BankBalance":bankBalance,"id":key!]
    refBanks.child(key!).setValue(updateBank)
    lblFireBaseKey.text = "Record updated..."
};
