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

问题描述

我想在 Parse.t 上的User"中的requestActive"中取回数据

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

我试试这个:

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

但是:错误实例成员 'user' 不能用于类型 'viewController'

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

推荐答案

您正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，仍然在根级别，您尝试将它与 user["requestActive"] 一起使用:您不能这样做.

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.

所以假设 user["requestActive"] 的类型是一个字符串(仅作为示例)，您可以执行以下操作:

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，您必须将 String 替换为您的实际类型.

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