#controller_for_url(url) ⇒ Object
Returns a UIViewController for the given url EX router.controller_for_url(“users/3”) => #<UsersController @id=‘3’>.
-
#map(url, klass = nil, options = {}, &callback) ⇒ Object
Map a URL to a UIViewController EX router.map “/users/:id”, UsersController PARAMS url => the URL to map klass (optional) => the UIViewController class to open options (optional) => hash of options &callback => the block to be run when opening the URL OPTIONS :modal => true/false - We present the VC modally (router is not shared between the new nav VC) :shared => true/false - If URL is called again, we pop to that VC if it’s in memory.
-
#open(url, animated = true) ⇒ Object
Push the UIViewController for the given url EX router.open(“users/3”) => router.navigation_controller pushes a UsersController.

#pop(animated = true) ⇒ Object
Pop the top level UIViewController EX router.pop.

Map a URL to a UIViewController EX router.map “/users/:id”, UsersController PARAMS

:modal => true/false
- We present the VC modally (router is not shared between the new nav VC)
:shared => true/false
- If URL is called again, we pop to that VC if it's in memory.
:transition => [:cover, :flip, :dissolve, :curl]
- A symbol to represented transition style used. Mapped to UIModalTransitionStyle.
:presentation => [:full_screen, :page_sheet, :form_sheet, :current]
- A symbol to represented presentation style used. Mapped to UIModalPresentationStyle.
