Handling openURL: with Facebook and Google

Question

user in my app can login using 2 services : Facebook or Google

everything works fine, however, in the :

- (BOOL)application:(UIApplication *)applicat         


        

Answer 1

The Swift version for iOS 9.0 and above of the accepted answer could be something like this:

import FacebookCore

[...]

    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        if (GIDSignIn.sharedInstance().handle(url)) {
            return true
        } else if (ApplicationDelegate.shared.application(app, open: url, options: options)) {
            return true
        }

        return false
    }

Try to handle the URL with each SDK, the first one that recognizes it ends execution returning true. If no SDK could handle the URL, return false.

I hope it helps someone,

Answer 2

This might be the easiest solution,

import GoogleSignIn
import FBSDKCoreKit

    func application(_ application: UIApplication,
                 open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    if GIDSignIn.sharedInstance().handle(url) {
        return true
    } else if ApplicationDelegate.shared.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation) {
        return true
    }
    
    return false
}

@available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
    if GIDSignIn.sharedInstance().handle(url) {
        return true
    } else if ApplicationDelegate.shared.application(app, open: url, sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String, annotation: options[UIApplication.OpenURLOptionsKey.annotation]
        ) {
        return true
    }
    return false
}

Answer 3

You'll want to use [[UIApplication sharedApplication] canOpenURL:]

Answer 4

For Swift users, (The idea from user2144179)

Import below frameworks

import Firebase
import GoogleSignIn
import FacebookCore // (FBSDKCore's alternative for swift)

and in your delegate methods

// when your target is under iOS 9.0
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    let isFBOpenUrl = SDKApplicationDelegate.shared.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
    let isGoogleOpenUrl = GIDSignIn.sharedInstance().handle(url, sourceApplication: sourceApplication, annotation: annotation)
    if isFBOpenUrl { return true }
    if isGoogleOpenUrl { return true }
    return false
}

or you can use another 'open url:' method if your target is 9.0+. SDKs include a method for it also.
