DeeplinkNavigator

Thanks for devxoul, this project is based & inspried on his effort.

Swift

DeeplinkNavigator can be used for mapping URL patterns with 2 kind of types: DeeplinkNavigable and DeeplinkOpenHandler. DeeplinkNavigable is a protocol which has 2 sub-protocols: StoryboardNavigable, InitNavigable (default init method for viewController). DeeplinkOpenHandler is a closure which can be executed. Both an initializer and a closure receive an URL and placeholder values.

Getting Started

1. Mapping URL Patterns

URL patterns can contain placeholders. Placeholders will be replaced with matching values from URLs. Use < and > to make placeholders. Placeholders can have types: string(default), int, float, and path.

Here’s an example of mapping URL patterns with view controllers and a closure. View controllers should conform a protocol DeeplinkNavigable to be mapped with URL patterns.

Navigator.map("myapp://user/<int:id>", UserViewController.self)
Navigator.map("myapp://post/<title>", PostViewController.self)

Navigator.map("myapp://alert") { url, values in
print(url.queryParameters["title"])
print(url.queryParameters["message"])
return true
}

Note: Global constant Navigator is a shortcut for DeeplinkNavigator.default.

2. Pushing, Presenting and Opening URLs

DeeplinkNavigator can push and present view controllers and execute closures with URLs.

Provide the from parameter to push() to specify the DeeplinkPushable which the new view controller will be pushed. Similarly, provide the from parameter to present() to specify the DeeplinkPresentable which the new view controller will be presented. If the nil is passed, which is a default value, current application’s top most view controller will be used to push or present view controllers.

present() takes an extra parameter: wrap. If true is specified, the new view controller will be wrapped with a UINavigationController. Default value is false.

Navigator.push("myapp://user/123")
Navigator.present("myapp://post/54321", wrap: true)

Navigator.open("myapp://alert?title=Hello&message=World")

3. Implementing DeeplinkNavigable

View controllers should conform a protocol DeeplinkNavigable to be mapped with URLs. A protocol DeeplinkNavigable defines 2 initialization protocols: StoryboardNavigable, InitNavigable with parameter navigation which contains url, values, mappingContext and navigationContext as properties.

Property url is an URL that is passed from DeeplinkNavigator.push() and DeeplinkNavigator.present(). Parameter values is a dictionary that contains URL placeholder keys and values. Parameter mappingContext is a context passed from a map() function. Parameter navigationContext is a dictionary which contains extra values passed from push() or present().

final class StoryboardViewController: UIViewController {
}

extension StoryboardViewController: StoryboardNavigable {
static func viewControllerFromStoryBoard(navigation: DeeplinkNavigation) -> UIViewController? {
let sb = UIStoryboard(name: "Main", bundle: nil)
let vc = sb.instantiateViewController(withIdentifier: String(describing: self))
return vc
}
}

final class XibViewController: UIViewController {
}

extension XibViewController: InitNavigable {
convenience init?(navigation: DeeplinkNavigation) {
self.init()
}
}

final class InitViewController: UIViewController {
}

extension InitViewController: InitNavigable {
convenience init?(navigation: DeeplinkNavigation) {
self.init()
}
}

Tips and Tricks

Where to Map URLs

I’d prefer using separated URL map file.

struct NavigationMap {

static func initialize() {
Navigator.map("myapp://user/<int:id>", UserViewController.self)
Navigator.map("myapp://post/<title>", PostViewController.self)

Navigator.map("myapp://alert") { url, values in
print(url.queryParameters["title"])
print(url.queryParameters["message"])
self.someUtilityMethod()
return true
}
}

private static func someUtilityMethod() {
print("This method is really useful")
}

}

Then call initialize() at AppDelegate‘s application:didFinishLaunchingWithOptions:.

@UIApplicationMain
final class AppDelegate: UIResponder, UIApplicationDelegate {

func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
) -> Bool {
// Navigator
URLNavigationMap.initialize()

// Do something else...
}
}

Passing UIView to push() or present()

Sometime you having a mutiple windows hierarchy situation, you can pass a UIView object
and let DeeplinkNavigator to find the right UINavigationController or UIViewController
for you.

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath)
Navigator.push("myapp://test", from: cell, animated: true)
}

Using pushOrPopTo extenstion

You want to push a viewController, but you also want to pop to that viewController if it
exist already.

Navigator.popTo("myapp://user")
Navigator.pushOrPopTo("myapp://user/10")

Implementing AppDelegate Launch Option URL

It’s available to open your app with URLs if custom schemes are registered. In order to navigate to view controllers with URLs, you’ll have to implement application:didFinishLaunchingWithOptions: method.

func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
) -> Bool {
// ...
if let url = launchOptions?[.url] as? URL {
if let opened = Navigator.open(url)
if !opened {
Navigator.push(url)
}
}
return true
}

Implementing AppDelegate Open URL Method

You’ll might want to implement custom URL open handler. Here’s an example of using DeeplinkNavigator with other URL open handlers.

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
// If you're using Facebook SDK
let fb = FBSDKApplicationDelegate.sharedInstance()
if fb.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation) {
return true
}

// DeeplinkNavigator Handler
if Navigator.open(url) {
return true
}

// DeeplinkNavigator View Controller
if Navigator.present(url, wrap: true) != nil {
return true
}

return false
}

Setting Default Scheme

Set scheme property on DeeplinkNavigator instance to get rid of schemes in every URLs.

Navigator.scheme = "myapp"
Navigator.map("/user/<int:id>", UserViewController.self)
Navigator.push("/user/10")

This is totally equivalent to:

Navigator.map("myapp://user/<int:id>", UserViewController.self)
Navigator.push("myapp://user/10")

Setting scheme property will not affect other URLs that already have schemes.

Navigator.scheme = "myapp"
Navigator.map("/user/<int:id>", UserViewController.self) // `myapp://user/<int:id>`
Navigator.map("http://<path>", MyWebViewController.self) // `http://<path>`

Passing Context when Mapping

let context = Foo()
Navigator.map("myapp://user/10", UserViewController.self, context: context)

Passing Extra Values when Pushing or Presenting

let context: [AnyHashable: Any] = [
"fromViewController": self
]
Navigator.push("myapp://user/10", context: context)
Navigator.present("myapp://user/10", context: context)
