从Swift中的Firebase获取单独的数据

Question

我无法获取数据并写入String变量。

当我这样做时：

Optional({
    TD =     {
        Entry = 44;
        Name = Tedd;
        Potential = 32;
        StopLoss = 77;
    };
})

我得到所有这些记录（在类型中 - AnyObject）：

{{1}}

但是我需要“Entry”，“Name”，“Potential”，“StopLoss” - 放入变量，然后放到textfield ......

请帮助理解，我该怎么做。 我已经找不到解决方案已经4个多小时.... 感谢。

Answer 1

You are trying to print a value associated with a key. ( a key:value pair)

The key you are specifying is "02-03-2016" and that key doesn't seem to exist.

Assuming your structure is

    Entry = 44;
    Name = Tedd;
    Potential = 32;
    StopLoss = 77;

Then your keys are Entry, Name, Potential and StopLoss

print(snapshot.value.objectForKey("Entry")

would print

44
