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
  1. 如果是网络地址,会直接自动跳转到 OtherWKWebViewController
  2. 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")
  1. 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

    private static let RouteDict:[String:String] = [
        "order/list"            :"OrderListPageViewController",   // 订单列表 segmentIndex
        "order/detail"          :"OrderDetailViewController",     // 订单详情 orderId
        "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
    ]
