ios - 从 Firebase 检索数据到标签 'Swift Project'

Question

我应该用来从 Firebase 检索数据到标签的函数的正确语法是什么？

例如，我想检索电子邮件和密码 in the picture here

我已经尝试过下面的代码，但它不起作用!它在模拟器中没有检索到任何东西!

    ref.observeEventType(.Value, withBlock: {
        snapshot  in let m = snapshot.value.objectForKey("users/\(self.ref.authData.uid)/email") as? String
        self.EmailLabel.text = m

    })

Answer 1

试试这个

var ref = Firebase(url:"YOUR_URL_PATH/Users")

ref.observeEventType(.Value, withBlock: { snapshot in
        let m = snapshot.value.objectForKey("Email")as?
        self.EmailLabel.text = m
}, withCancelBlock: { error in
    println(error.description)
})

希望这对您有帮助...
