如何在Parse上取回用户数据? [英] How can I get back data of user on Parse?

问题描述

我想获取Parse.t上用户"中"requestActive"中的数据

I want to get back data in "requestActive" in "User" on Parse.t

我尝试这个:

var user = PFUser()
var requestActive = user["requestActive"]

但是:错误实例成员'user'不能在'viewController'类型上使用

but : error "instance member 'user' cannot be used on type 'viewController'

推荐答案

您要在视图控制器的顶层声明user.

You are declaring user at the top level of your view controller.

但是，仍然在根目录下，尝试将其与user["requestActive"]一起使用:您无法做到这一点.

But then, still at the root level, you try to use it with user["requestActive"]: you can't do that.

您必须在方法中使用user ，例如viewDidLoad.

You have to use user in a method, for example viewDidLoad.

因此，假设user["requestActive"]的类型为String(仅用于示例)，您将执行以下操作:

So let's say the type of user["requestActive"] would be a String (just for the example), you would do something like:

var user = PFUser()
var requestActive: String?

override func viewDidLoad() {
    super.viewDidLoad()
    requestActive = user["requestActive"]
}

当然，您必须用实际类型替换String.

Of course, you have to replace String with your actual type.
