使CAShapeLayer和CGPath符合Codable或NSCoding

class CodableCAShapeLayer: Codable {
    var path: CGPath?
    var fillColor: CGColor?
    var strokeColor: CGColor?
    // 其他CAShapeLayer的属性
    
    enum CodingKeys: String, CodingKey {
        case path
        case fillColor
        case strokeColor
        // 其他CAShapeLayer的属性对应的CodingKey
    }
    
    func encode(to encoder: Encoder) throws {
        var container = encoder.container(keyedBy: CodingKeys.self)
        try container.encode(path, forKey: .path)
        try container.encode(fillColor, forKey: .fillColor)
        try container.encode(strokeColor, forKey: .strokeColor)
        // 编码其他CAShapeLayer的属性
    }
    
    required init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        path = try container.decode(CGPath.self, forKey: .path)
        fillColor = try container.decode(CGColor.self, forKey: .fillColor)
        strokeColor = try container.decode(CGColor.self, forKey: .strokeColor)
        // 解码其他CAShapeLayer的属性
    }
}

class NSCodingCAShapeLayer: NSObject, NSCoding {
    var path: CGPath?
    var fillColor: CGColor?
    var strokeColor: CGColor?
    // 其他CAShapeLayer的属性
    
    enum CodingKeys: String {
        case path
        case fillColor
        case strokeColor
        // 其他CAShapeLayer的属性对应的CodingKey
    }
    
    func encode(with coder: NSCoder) {
        coder.encode(path, forKey: CodingKeys.path.rawValue)
        coder.encode(fillColor, forKey: CodingKeys.fillColor.rawValue)
        coder.encode(strokeColor, forKey: CodingKeys.strokeColor.rawValue)
        // 编码其他CAShapeLayer的属性
    }
    
    required init?(coder: NSCoder) {
        path = coder.decodeObject(forKey: CodingKeys.path.rawValue) as? CGPath
        fillColor = coder.decodeObject(forKey: CodingKeys.fillColor.rawValue) as? CGColor
        strokeColor = coder.decodeObject(forKey: CodingKeys.strokeColor.rawValue) as? CGColor
        // 解码其他CAShapeLayer的属性
    }
