抽象工厂角色划分
特点->比工厂方法产品种类多
模块：地图MapView模块、定位模块、导航模块、搜索模块…
工厂方法模式：只有1条流水线
创建MapView（产品）
抽象工厂模式：至少2条流水线
创建MapView（产品）
多个产品->多个抽象产品
MapView->抽象->MapViewProtocol
MapLocation->抽象->MapLocationProtocol
MapNavigation->抽象->MapNavigationProtocol
……
简单工厂->抽象->工厂方法（抽象单个产品）->抽象（抽象多个产品）->抽象工厂
分析角色？
角色一：抽象产品A->MapViewProtocol
角色二：抽象产品B->MapLocationProtocol
…
角色三：具体产品A1->BaiduMapView
角色四：具体产品A2->GaodeMapView
…
角色五：具体产品B1->BaiduMapLocation
角色六：具体产品B2->GaodeMapLocation
…
角色七：抽象工厂->MapFactoryProtocol
角色八：具体工厂A->BaiduMapFactory->这里设置第三方初始化的代码
角色九：具体工厂B->GaodeMapFactory->这里设置第三方初始化的代码
