如何修复 swift 3 嵌套通用错误

Question

下面的代码

https://i.stack.imgur.com/07Jry.png

class BaseModel {

}

class BaseView<T: BaseModel> {

}

class BaseController<T: BaseView<BaseModel>> {

}

class MarketModel: BaseModel {

}

class InfoModel: BaseModel {

}

class MarketView: BaseView<MarketModel> {

}

class InfoView: BaseView<InfoModel> {

}

class MarketViewController: BaseController<MarketView> {

}

class InfoViewController: BaseController<InfoView> {

}

我收到这样的错误消息

“BaseController”要求“MarketView”继承自“BaseView”

“BaseController”要求“InfoView”继承自“BaseView”

我该如何解决这个问题？

Answer 1

我用以下代码解决了这个错误：

class BaseModel {

}

class BaseView<T: BaseModel> {

}

class BaseController<T, U: BaseView<T>> {

}

class MarketModel: BaseModel {

}

class InfoModel: BaseModel {

}

class MarketView: BaseView<MarketModel> {

}

class InfoView: BaseView<InfoModel> {

}

class MarketViewController: BaseController<MarketModel, MarketView> {

}

class InfoViewController: BaseController<InfoModel, InfoView> {

}
