iOS使用Swift行为解析PFObject子类 [英] iOS Parse PFObject Subclassing with Swift Behaviour

问题描述

我有一个奇怪的问题，我的子类可以在我的所有视图控制器中工作，除了一个。

I have a strange issue, my subclassing works in all my view controllers except one.

我已经导入了所有必需的东西，但是这一课给了我

I have imported everything that is required, but this one class is giving me the

调用中参数'className'缺少参数

"Missing argument for parameter 'className' in call"

我的子类

import Foundation
import Parse

class Session : PFObject, PFSubclassing {

    class func parseClassName() -> String {
        return "Session"
    }

}

//我删除了非重要信息

// i have removed the non important info

我执行

Session.registerSubclass()

在app delegate中

In the app delegate

在每个班级，我都可以通过

In EVERY class I have i can create a session via

var se = Session()

但在这一课中，这不起作用。

But in this one class, this will not work.

班级

import UIKit
import Parse

class PurchaseViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        var se = Session()
        // gives me an the above error
    }

}

我尝试删除课程，即使是新课程也要创建一个新课程名称 - 仍然不起作用。

I've tried deleting the class, creating a new one even with a new name - still does not work.

好的......做的东西我尝试从对象创建工作的类中删除一些本地类Vars，我发现通过删除

Ok... something made me try removing some local class Vars from the classes where the object creation works, I found that by removing

let currentUser = PFUser.currentUser()! as! FighterUser

//这是我的子类PFUser对象

// This is my subclassed PFUser object

导致该类抛出错误，并将此var添加到之前无效的ViewController中停止错误

Causes that class to throw there error, and adding this var into the ViewController that was not working before stops the error

任何关于如何/为什么的逻辑这会发生吗？一个错误？

这是有效的

import Parse
import UIKit

class PurchaseViewController: UIViewController {

let currentUser = PFUser.currentUser()! as! FighterUser

override func viewDidLoad() {
    super.viewDidLoad()

    var se = Session()

}

更多信息2

即使只是添加

let currentUser = PFUser.currentUser()

删除错误
