ReerRouter

App URL router for iOS (Swift only). Inspired by URLNavigator.

Example App

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

At least iOS 10.0 Xcode 13.2

Installation

CocoaPods

ReerRouter is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'ReerRouter'

Swift Package Manager

import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    targets: [],
    dependencies: [
        .package(url: "https://github.com/reers/ReerRouter.git", from: "1.0.1")
    ]
)

Next, add ReerRouter to your targets dependencies like so:

.target(
    name: "YOUR_TARGET_NAME",
    dependencies: ["ReerRouter",]
),

Getting Started

1. Understanding Route.Key

There are two modes of Route.Key.

Mode 1: Route.Key means URL host + path

/// myapp://example.com/over/there?name=phoenix#nose
/// \______/\_________/\_________/ \__________/ \__/
///    |         |          |           |        |
///  scheme     host       path      queries   fragment
///              \_________/
///                   |
///               route key

Mode 1: Set host for router instance and use path as the Route.Key.

/// myapp://example.com/over/there?name=phoenix#nose
/// \______/\_________/\_________/ \__________/ \__/
///    |         |          |           |        |
///  scheme     host       path      queries   fragment
///                         |
///                         |
///                    route key

2. Register Route

Mode 1

Now Route.Key means the combination of url host and path.

  • Register an action.
Router.shared.registerAction(with: "abc_action") { _ in
    print("action executed.")
}
  • Register a view controller by its type and a route key.
extension Route.Key {
    static let userPage: Self = "user"
}
Router.shared.register(UserViewController.self, forKey: .userPage)
Router.shared.register(UserViewController.self, forKey: "user")
  • Register view controllers by their types and route keys.
Router.shared.registerPageClasses(with: ["preference": PreferenceViewController.self])
  • Register view controllers by their type names and route keys.
Router.shared.registerPageClasses(with: ["preference": "ReerRouter_Example.PreferenceViewController"])

Mode 2

Firstly, you should set host for router instance.

Router.shared.host = "phoenix.com"

And now Route.Key means url path, then all the register methods are same as Mode 1. ("path", "/path" both are supported.)

  • Implement Routable for view controller.
class UserViewController: UIViewController, Routable {
    var params: [String: Any]
    
    required init?(param: Route.Param) {
        self.params = param.allParams
        super.init(nibName: nil, bundle: nil)
    }
}   

3. Execute an route action.

Router.shared.executeAction(byKey: "abc_action")

// Mode 1.
Router.shared.open("myapp://abc_action")

// Mode 2.
Router.shared.open("myapp://phoenix.com/abc_action")

4. Open a view controller.

Router.shared.present(byKey: .userPage, embedIn: UINavigationController.self, userInfo: [
    "name": "apple",
    "id": "123123"
])

// Mode 1.
Router.shared.open("myapp://user?name=phoenix")
Router.shared.push("myapp://user?name=phoenix")
Router.shared.present("myapp://user?name=phoenix")

// Mode 2.
Router.shared.open("myapp://phoenix.com/user?name=phoenix")
Router.shared.push("myapp://phoenix.com/user?name=phoenix")
Router.shared.present("myapp://phoenix.com/user?name=phoenix")

5. Delegate for for the app about the route.

extension RouteManager: RouterDelegate {
    func router(_ router: Router, willOpenURL url: URL, userInfo: [String : Any]) -> URL? {
        print("will open \(url)")
        if let _ = url.absoluteString.range(of: "google") {
            return URL(string: url.absoluteString + "&extra1=234244&extra2=afsfafasd")
        } else if let _ = url.absoluteString.range(of: "bytedance"), !isUserLoggedIn() {
            print("intercepted by delegate")
            return nil
        }
        return url
    }

    func router(_ router: Router, didOpenURL url: URL, userInfo: [String : Any]) {
        print("did open \(url) success")
    }
    
    func router(_ router: Router, didFailToOpenURL url: URL, userInfo: [String : Any]) {
        print("did fail to open \(url)")
    }
    
    func router(_ router: Router, didFallbackToURL url: URL, userInfo: [String: Any]) {
        print("did fallback to \(url)")
    }
}

6. Fallback

  • Use route_fallback_url key as a fallback url when some thing went wrong.
Router.shared.open("myapp://unregisteredKey?route_fallback_url=myapp%3A%2F%2Fuser%3Fname%3Di_am_fallback")

7. Redirect

  • Implement redirectURLWithRouteParam(_:) method to redirect to a new url for the view controller.
class PreferenceViewController: UIViewController, Routable {
    
    required init?(param: Route.Param) {
        super.init(nibName: nil, bundle: nil)
    }
    
    class func redirectURLWithRouteParam(_ param: Route.Param) -> URL? {
        if let value = param.allParams["some_key"] as? String, value == "redirect" {
            return URL(string: "myapp://new_preference")
        }
        return nil
    }
}

8. Global instance for the router singleton.

public let AppRouter = Router.shared
AppRouter.open("myapp://user")

9. Notifications when will open and did open.

NotificationCenter.default.addObserver(
    forName: Notification.Name.routeWillOpenURL,
    object: nil,
    queue: .main
) { notification in
    if let param = notification.userInfo?[Route.notificationUserInfoKey] as? Route.Param {
        print("notification: route will open \(param.sourceURL)")
    }
}

NotificationCenter.default.addObserver(
    forName: Notification.Name.routeDidOpenURL,
    object: nil,
    queue: .main
) { notification in
    if let param = notification.userInfo?[Route.notificationUserInfoKey] as? Route.Param {
        print("notification: route did open \(param.sourceURL)")
    }
}

10. Custom controlling for transition.

public typealias UserTransition = (
    _ fromNavigationController: UINavigationController?,
    _ fromViewController: UIViewController?,
    _ toViewController: UIViewController
) -> Bool

public enum TransitionExecutor {
    /// Transition will be handled by router automatically.
    case router
    /// Transition will be handled by user who invoke the router `push` or `present` method.
    case user(UserTransition)
    /// Transition will be handled by user who invoke the router `push` or `present` method.
    case delegate
}

let transition: Route.UserTransition = { fromNavigationController, fromViewController, toViewController in
    toViewController.transitioningDelegate = self.animator
    toViewController.modalPresentationStyle = .currentContext
    // Use the router found view controller directly, or just handle transition by yourself.
    // fromViewController?.present(toViewController, animated: true)
    self.present(toViewController, animated: true)
    return true
}
AppRouter.present(user.urlString, transitionExecutor: .user(transition))

11. Open style for UIViewController.

The priority levels on which the way router opens the controller depend are as follows:

`Router` instance property `preferredOpenStyle` <
  `Routable` property `preferredOpenStyle` that UIViewController implemented <
    The method you called. If you called `Router.push(...)`, the view controller will be pushed.

12. Forbidden transition animation.

  • Use route_no_animation key to forbidden animation.
Router.shared.open("myapp://user?name=google&route_no_animation=1")

13. Intercept by external.

Intercept a route in some special scenarios, return false means to intercept the url.

Router.shared.addInterceptor(forKey: .userPage) { (_) -> Bool in
    print("intercepted user page")
    return true
}

Router.shared.addInterceptor(forKey: .userPage) { (params) -> Bool in
    print("intercepted user page")
    if let name = params.allParams["name"] as? String, name == "google" {
        print("intercepted user page success")
        return false
    }
    return true
}
