¶ Line Login
¶ Preparation
Configure in Line Development Platform (opens new window) and Authing Console (opens new window), please refer to [Line Access Preparation](. ./../../guides/connections/social/line-mobile/README.md) and [Line iOS access document](https://developers.line.biz/en/docs/ios-sdk/swift /integrate-line-login/).
¶ Integrated Line login
¶ Step 1: Add Line dependency
Enter: https://github.com/Authing/authing-binary in the swift package search bar.
Authing-binary (opens new window) depends on Guard-iOS SDK (opens new window).
Select Up to Next Major Version 1.0.0 for the dependency rule.
Check Line after Add Package.
Line depends on the version after Guard-iOS 1.4.5 (opens new window).
¶ Step 2: Set up Associated Domains:
Fill in the host corresponding to the developer's Universal Link.
¶ Step 3: Initialize Line login
import Guard
import Line
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
Authing.start(<#AUTHING_APP_ID#>)
// channelID: Line open platform channelID
// universalLink: UniversalLink filled in by the Line open platform
Line.register(channelID: <#your_line_channelId#>, universalLinkURL: <#your_line_universalLink#>)
}
¶ Step 4: Handle the Line login callback
After Line returns to the application, if SceneDelegate is used, the following function needs to be overloaded in SceneDelegate.swift:
func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
_ = Line. application(. shared, open: url)
}
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
_ = Line. application(. shared, open: url)
}
If SceneDelegate is not used, it needs to be overloaded in AppDelegate:
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
return Line. application(application, open: url)
}
func application(_ app: UIApplication, open url: URL, options: [UIApplication. OpenURLOptionsKey : Any] = [:]) -> Bool {
return Line. application(app, open: url)
}
¶ Step 5: Initiate Line login authorization
¶ Line authorization login
func login(viewController: UIViewController, permissions: [String] = ["openid","profile"], completion: @escaping Authing.AuthCompletion) -> Void
example
Line.login(viewController: <#ViewController#>) { code, message, userInfo in
if (code == 200) {
// login successful
// userInfo
}
}
If the developer integrates Line login by himself, after getting the accessToken, he can call the following API in exchange for Authing user information:
¶ Login via Line Authorization Code
func loginByLine(_ accessToken: String, _ idToken: String? = nil, completion: @escaping(Int, String?, UserInfo?) -> Void)
parameter
accessToken Line accessToken idToken Line idToken
example
AuthClient().loginByLine(<#accessToken#>, <#idToken#>) { code, message, userInfo in
if (code == 200) {
// userInfo: user information
}
}
