Swift-Router 自己写个路由吧，第三方总是太复杂
Swift-Router 自己写个路由吧，第三方总是太复杂
先看看这个路由的使用吧
- 如果是网络地址，会直接自动跳转到 OtherWKWebViewController
- 如果是应用内部的手动调用跳转
- 直接跳转视图控制器
- EPRouter.pushViewController(EPSMSLoginViewController())
- 先在 RouteDict 注册映射关系再跳转
- EPRouter.pushAppURLPath("goods/detail?spellId=xxx&productId=xxx")
- 又服务器来控制跳转 也得在 RouteDict 注册映射关系，只不过多加了一个 scheme
- EPRouter.pushURLPath("applicationScheme://goods/detail?spellId=xxx&productId=xxx")
**！！！支持Swift、OC、Storyboard的跳转方式，可以在 loadViewController 看到实现方式 **
EPRouter的全部代码

"goods/detail" :"GoodsDetailViewController", // 商品详情productId
"goods/list" :"GoodsCategoryViewController", // type brandId 跳转到某个分类；跳转到某个品牌
"goods/search" :"SearchListViewController", // 搜索商品 text
"coupon/list" :"CouponListViewController", // 优惠券列表
"cart/list" :"CartViewController", // 购物车列表
"address/list" :"AddressListViewController", // 收货地址列表
]
// 返回首页，然后指定选中模块
