facebook openurl for login in ios 9 method ios swift

Question

I have both facebook and gmail integration in my app but as soon as I add the open url function for gmail login the facebook login stops working. I have this code for open url in my app

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(application,openURL: url,sourceApplication: sourceApplication,annotation: annotation)

    shouldOpen = shouldOpen ? shouldOpen : GIDSignIn.sharedInstance().handleURL(url,
                                                                                sourceApplication: sourceApplication,
                                                                                annotation: annotation)

    return shouldOpen

}

This works fine with the facebook login but when I add openurl method for gmail for ios 9 the problem occures i.e. after facebook login we don't redirect back to the app. In simulator the white screen shows in safari. the code for the gmail login for ios 9

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    if #available(iOS 9.0, *) {

        return GIDSignIn.sharedInstance().handleURL(url,
                                                    sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String?,
                                                    annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
    }
    return true
}

If I comment out the above code the facebook login works correctly I guess the problem is that I have to return boolean for openurl of facebook in ios 9 as well. But I don't know what to do with this ? TIA

Answer 1

Found my answer i need to implement both methods of openurl Like this

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(application,openURL: url,sourceApplication: sourceApplication,annotation: annotation)

    shouldOpen = shouldOpen ? shouldOpen : GIDSignIn.sharedInstance().handleURL(url,
                                                                                sourceApplication: sourceApplication,
                                                                                annotation: annotation)
    return shouldOpen

}

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    if #available(iOS 9.0, *) {
        var shouldOpen :Bool = FBSDKApplicationDelegate.sharedInstance().application(
            app,
            openURL: url,
            sourceApplication: options["UIApplicationOpenURLOptionsSourceApplicationKey"] as! String,
            annotation: nil)

        shouldOpen = shouldOpen ? shouldOpen : GIDSignIn.sharedInstance().handleURL(url,sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String?,
                                                                                    annotation: options[UIApplicationOpenURLOptionsAnnotationKey])

        return shouldOpen
    }
    return true
}

i just need to check for facebook open url method for ios 9 as well

Edit for swift 3.0 the function changed

private func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {


    return  FBSDKApplicationDelegate.sharedInstance().application(application,open: url as URL!,sourceApplication: sourceApplication,annotation: annotation)

}

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    if #available(iOS 9.0 , *){
     return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: "UIApplicationOpenURLOptionsKey", annotation: nil)   

    }

return true
}
