Earlier I have published a video tutorial on Sign-in with Facebook account and Sign-in with Twitter account. In this video tutorial I am going to share with you how to implement Sign-in with Google account feature for your mobile app.
I hope you find these two videos valuable.
If you are interested in learning more about User Sing-up for your mobile app process with either Parse or PHP & MySQL, there are more videos I have which I have organized into two videos courses:
1. Sign-in & Sign-up with Swift & Parse video course: https://goo.gl/a4jWz1
2. Sign-in & Sign-up with Swift, PHP and MySQL: https://goo.gl/CG4xKY
and here is now Sign-in with Google Account:
Link to Google Guides on Sign-in with Google Account.
Video 1. Configure Xcode project.
Video 2. Implement Sign-in and Sign out button
AppDelegate source code:
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
// Initialize sign-in
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
GIDSignIn.sharedInstance().delegate = self
return true
}
func application(application: UIApplication,
openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
return GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: sourceApplication,
annotation: annotation)
}
func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!,
withError error: NSError!) {
if (error == nil) {
// Perform any operations on signed in user here.
//let userId = user.userID // For client-side use only!
//let idToken = user.authentication.idToken // Safe to send to the server
let name = user.profile.name
//let email = user.profile.email
print("User name \(name)")
// [START_EXCLUDE]
NSNotificationCenter.defaultCenter().postNotificationName(
"ToggleAuthUINotification",
object: nil,
userInfo: ["statusText": "Signed in user:\n\(name)"])
// [END_EXCLUDE]
let myStoryBoard:UIStoryboard = UIStoryboard(name:"Main", bundle:nil)
let protectedPage = myStoryBoard.instantiateViewControllerWithIdentifier("ProtectedPageViewController") as! ProtectedPageViewController
let protectedPageNav = UINavigationController(rootViewController: protectedPage)
self.window?.rootViewController = protectedPageNav
} else {
print("\(error.localizedDescription)")
// [START_EXCLUDE silent]
NSNotificationCenter.defaultCenter().postNotificationName(
"ToggleAuthUINotification", object: nil, userInfo: nil)
// [END_EXCLUDE]
}
}
func signIn(signIn: GIDSignIn!, didDisconnectWithUser user:GIDGoogleUser!,
withError error: NSError!) {
// Perform any operations when the user disconnects from app here.
// [START_EXCLUDE]
NSNotificationCenter.defaultCenter().postNotificationName(
"ToggleAuthUINotification",
object: nil,
userInfo: ["statusText": "User has disconnected."])
// [END_EXCLUDE]
}
func applicationWillResignActive(application: UIApplication) {
}
func applicationDidEnterBackground(application: UIApplication) {
}
func applicationWillEnterForeground(application: UIApplication) {
}
func applicationDidBecomeActive(application: UIApplication) {
}
func applicationWillTerminate(application: UIApplication) {
}
}
