如何将NSManagedObject类型转换为NSItemProviderWriting/NSItemProviderReading？

extension YourManagedObjectSubclass: NSItemProviderWriting {
    static var writableTypeIdentifiersForItemProvider: [String] {
        return ["com.yourapp.yourManagedObjectSubclass"]
    }
    
    func loadData(withTypeIdentifier typeIdentifier: String, forItemProviderCompletionHandler completionHandler: @escaping (Data?, Error?) -> Void) -> Progress? {
        // 将NSManagedObject转换为Data，并通过completionHandler返回
        // 注意：需要自行实现将NSManagedObject转换为Data的逻辑
    }
}

extension YourManagedObjectSubclass: NSItemProviderReading {
    static var readableTypeIdentifiersForItemProvider: [String] {
        return ["com.yourapp.yourManagedObjectSubclass"]
    }
    
    static func object(withItemProviderData data: Data, typeIdentifier: String) throws -> Self {
        // 将Data转换为NSManagedObject，并返回
        // 注意：需要自行实现将Data转换为NSManagedObject的逻辑
    }
}

let managedObject = // 获取到的NSManagedObject对象
let itemProvider = NSItemProvider(object: managedObject)

let typeIdentifier = "com.yourapp.yourManagedObjectSubclass"
itemProvider.loadDataRepresentation(forTypeIdentifier: typeIdentifier) { (data, error) in
    if let error = error {
        // 处理错误
    } else if let data = data {
        // 处理加载的数据
        // 注意：需要自行处理将Data转换为NSManagedObject的逻辑
    }
}
