工程中有很多个VC的话，是否都需要在didFinishLaunchingWithOptions中注册呢？ #26
Description
[[Routable sharedRouter] map:@"user" toController:[UserController class]];
[[Routable sharedRouter] map:@"modal" toController:[ModalController class] withOptions:[[UPRouterOptions modal] withPresentationStyle:UIModalPresentationFormSheet]];
如上代码，demo中是有2个vc，都注册了。如果有N个的话，那就要注册N次么？期待你的答疑。
