抽象工廠角色劃分

特點(diǎn)->比工廠方法產(chǎn)品種類多
模塊：地圖MapView模塊土至、定位模塊枝秤、導(dǎo)航模塊、搜索模塊…

工廠方法模式：只有1條流水線
創(chuàng)建MapView（產(chǎn)品）
抽象工廠模式：至少2條流水線
創(chuàng)建MapView（產(chǎn)品）
多個(gè)產(chǎn)品->多個(gè)抽象產(chǎn)品
MapView->抽象->MapViewProtocol
MapLocation->抽象->MapLocationProtocol
MapNavigation->抽象->MapNavigationProtocol
……

簡單工廠->抽象->工廠方法（抽象單個(gè)產(chǎn)品）->抽象（抽象多個(gè)產(chǎn)品）->抽象工廠
分析角色艘绍？
角色一：抽象產(chǎn)品A->MapViewProtocol
角色二：抽象產(chǎn)品B->MapLocationProtocol
…
角色三：具體產(chǎn)品A1->BaiduMapView
角色四：具體產(chǎn)品A2->GaodeMapView
…
角色五：具體產(chǎn)品B1->BaiduMapLocation
角色六：具體產(chǎn)品B2->GaodeMapLocation
…
角色七：抽象工廠->MapFactoryProtocol
角色八：具體工廠A->BaiduMapFactory->這里設(shè)置第三方初始化的代碼
角色九：具體工廠B->GaodeMapFactory->這里設(shè)置第三方初始化的代碼
