为什么HueSaturation.m不使用Swift

HueSaturation.m

Why this file use Object-C，Why not use Swift

[griffinTao]

class HueSaturation: NSObject, NSSecureCoding, NSCopying {

    static var supportsSecureCoding: Bool = true

    var hue: Double = 0
    var saturation: Double = 0

    override init() {
        super.init()
    }

    init(hue: Double, saturation: Double) {
        self.hue = hue
        self.saturation = saturation
        super.init()
    }

    required init?(coder aDecoder: NSCoder) {
        self.hue = aDecoder.decodeDouble(forKey: "hue")
        self.saturation = aDecoder.decodeDouble(forKey: "saturation")

        super.init()
    }

    func encode(with aCoder: NSCoder) {
        aCoder.encode(hue, forKey: "hue")
        aCoder.encode(saturation, forKey: "saturation")
    }

    func copy(with zone: NSZone? = nil) -> Any {
        let newInstance = HueSaturation(hue: self.hue, saturation: self.saturation)
        return newInstance
    }

    func interpolateBetween(rightValue: NSSecureCoding & NSCopying, withWeight weight: Float) -> NSSecureCoding & NSCopying {
        let result = HueSaturation(hue: self.hue, saturation: self.saturation)
        return result
    }

    func isEqual(to object: NSSecureCoding & NSCopying) -> Bool {
        guard let rhs = object as? HueSaturation else { return false }
        return self.hue == rhs.hue && self.saturation == rhs.saturation
    }
}

这个是代码，我把使用FxParameterRetrievalAPI_v6 -getCustomParameterValue部分给删除掉了，因为我更喜欢在外部调用getCustomParameterValue，稍后我会给出一个示例

[griffinTao]

        let paramAPI = _apiManager!.api(for: FxParameterRetrievalAPI_v6.self) as! FxParameterRetrievalAPI_v6
        var temColorManagementData: (any NSCopying & NSSecureCoding & NSObjectProtocol)? = nil
        paramAPI.getCustomParameterValue(&temColorManagementData, fromParameter: ParamsId.colorManagement.rawValue, at: renderTime)
        let newColorManagementData = temColorManagementData as! ColorManagementParams

这是一个使用示例，希望能对你有帮助

对了，这个示例并没有提供如何传递String或者[Float]类型，因为项目本身并不包含，如果需要的话，可以询问我，目前我也只有这两种方式的示例

I am use Chinese， maybe you need translate

[jslinker]

Because NSObject, NSSecureCoding, and NSCopying have conflicting function definitions in their protocols. Swift doesn't allow that but Objective-C does. Ideally there would be a very small Objective-C layer in this framework that handles just the incompatible parts, but I haven't gotten to that.

抱歉，我的工作更多是Python与Javascript，我并不是一个专业的apple开发者，没有办法给你提供帮助🌹
