我正在使用Dribbble API，我目前使用的模型有三种：
User Team Shot Shot是User或Team上传到各自的投资组合以展示的内容。这可以是图像或动画。 User可以属于多个Team，而Team可以有多个User。
这三个模型都有许多属性，我在下面提供了这些属性。
User采用以下结构：
/// Encapsulates information about a Dribbble User.
public struct User {
// MARK: - Properties
/// The identifier of the User.
public var identifier: Int?
/// The name of the User.
public var name: String?
/// The username of the User.
public var username: String?
/// The `URL` for the User's Dribbble page.
public var htmlURL: URL?
/// The `URL` for the User's avatar image.
public var avatarURL: URL?
/// The biography for the User.
public var biography: String?
/// The location for the User.
public var location: String?

}
Shot采用以下结构：

/// The identifier of the Shot.

/// The title of the Shot.
public var title: String?

/// The size of the Shot.
public var size: CGSize?
/// The `URL` for the Shot's high-definition image.
public var highDefinitionImageURL: URL?
/// The `URL` for the Shot's normal image.
public var normalImageURL: URL?
/// The `URL` for the Shot's teaser image.
public var teaserImageURL: URL?
/// The number of views for the Shot.
public var viewsCount: Int?
/// The number of likes for the Shot.

/// The number of comments for the Shot.
public var commentsCount: Int?
/// The number of attachments for the Shot.
public var attachmentsCount: Int?
/// The number of Rebounds for the Shot.
public var reboundsCount: Int?
/// The number of Buckets for the Shot.
public var bucketsCount: Int?
/// The `Date` that the Shot was created.
public var createdAt: Date?

public var updatedAt: Date?
/// The `URL` for the Shot's Dribbble page.
public var htmlURL: URL?
/// The `URL` for the Shot's attachments.
public var attachmentsURL: URL?

public var likesURL: URL?
/// The `URL` for the Shot's Projects.
public var projectsURL: URL?
/// The `URL` for the Shot's Rebounds.
public var reboundsURL: URL?
/// Whether the Shot is animated.
public var isAnimated: Bool?
/// The tags associated with the Shot.
public var tags: Array<String>?
/// The `User` that the Shot belongs to.
public var user: User?
/// The `team` that she Shot belongs to.
public var team: Team?
}
User和Team有许多重复的属性，而Shot有一些User和Team。如果我采用这些模型的协议路由，将会有许多协议实现。
在我的情况下，我没有理由拥有Array个Identifiable类型或WebsiteURL类型，或任何其他符合重复属性协议的类型。我将Array Shot个User，属于Team个或Array个。对于User我也会Arrays，Team会User。
我是否应该为重复的属性实现协议并让Team，Shot和String REFERSH_QUERY = "refresh materialized view " + viewName;
Query query = entityManager.createNativeQuery(REFERSH_QUERY);
query.executeUpdate();符合它们，否则这会导致协议地狱除了如此之外没有明显的好处 - 被叫＆＃34; Swifty＆＃34;？
答案 0 :(得分：1)
那么使用像这样的继承呢
普通父母获取Shot，用户和团队拥有的属性，用户和团队的父级仅使用属性用户和团队
