在Swift中对PFObject进行子类化 [英] Subclassing PFObject in Swift

问题描述

在PFObject子类上添加属性和方法的Parse文档在其示例代码中方便地跳过了Swift语法，列出了Objective-C语法：

The Parse documentation for adding properties and methods on PFObject subclasses conveniently skips the Swift syntax in their sample code listing just the Objective-C syntax:

https://parse.com/docs/ios_guide#subclasses-properties/iOS

// Armor.h
@interface Armor : PFObject<PFSubclassing>
+ (NSString *)parseClassName;
@property (retain) NSString *displayName;
@end

// Armor.m
@dynamic displayName;

有没有人想办法解决Swift缺乏动态合成器以实现属性和方法的问题PFSubclassing？我希望能够做类似的事情：

Has anyone figured out a work around for Swift's lack of dynamic synthesizers in order to implement properties and methods with PFSubclassing? I want to be able to do something like:

class Armor : PFObject, PFSubclassing {
    class func parseClassName() -> String! {
        return "Armor"
    }
}

var armor = Armor()
armor.displayName = "Iron Clad"

推荐答案

我遇到了同样的问题。不得不将@NSManaged添加到我想保存的属性中：

I had this same problem. Had to add @NSManaged to the properties I wanted saved:

class Armor : PFObject, PFSubclassing {
    @NSManaged var displayName: String

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

var armor = Armor.object()
armor.displayName = "Iron Clad"

希望在下次更新时解决此问题。

Hopefully this is resolved in the next update.
