In this video tutorial I am going to share with you how to integrate Facebook SDK for iOS platform into your Swift mobile app that uses Parse Cloud Service as it’s app back end.
If you are interested to learn how to implement features User Sign up, Sign in, Password reset, Email verification, Profile details update together with Left Side Sliding Navigation menu and other features with Swift and Parse SDK for iOS, please check out my video course which will guide you through implementation of these features step by step and will save you a lot of time 🙂 https://goo.gl/DJ5TG4
Integrate Facebook SDK for iOS platform and Parse SDK for iOS platform into Swift project
AppDelegate source code:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
Parse.setApplicationId("YOU APP ID", clientKey: "YOUR CLIENT KEY")
PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
return true
}
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}
func applicationWillResignActive(application: UIApplication) {
}
func applicationDidEnterBackground(application: UIApplication) {
}
func applicationWillEnterForeground(application: UIApplication) {
}
func applicationDidBecomeActive(application: UIApplication) {
FBSDKAppEvents.activateApp()
}
func applicationWillTerminate(application: UIApplication) {
}
Implement Facebook Login and Logout buttons
Facebook Sign in button tapped function source code:
@IBAction func signInButtonTapped(sender: AnyObject) {
PFFacebookUtils.logInInBackgroundWithReadPermissions(["public_profile","email"], block: { (user:PFUser?, error:NSError?) -> Void in
if(error != nil)
{
//Display an alert message
var myAlert = UIAlertController(title:"Alert", message:error?.localizedDescription, preferredStyle: UIAlertControllerStyle.Alert);
let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)
myAlert.addAction(okAction);
self.presentViewController(myAlert, animated:true, completion:nil);
return
}
println(user)
println("Current user token=\(FBSDKAccessToken.currentAccessToken().tokenString)")
println("Current user id \(FBSDKAccessToken.currentAccessToken().userID)")
if(FBSDKAccessToken.currentAccessToken() != nil)
{
let protectedPage = self.storyboard?.instantiateViewControllerWithIdentifier("ProtectedPageViewController") as! ProtectedPageViewController
let protectedPageNav = UINavigationController(rootViewController: protectedPage)
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.window?.rootViewController = protectedPageNav
}
})
}
Load Facebook user profile details and store it in Parse Users Class
Load Facebook user profile details and store them in Parse Users Class
var requestParameters = ["fields": "id, email, first_name, last_name"]
let userDetails = FBSDKGraphRequest(graphPath: "me", parameters: requestParameters)
userDetails.startWithCompletionHandler { (connection, result, error:NSError!) -> Void in
if(error != nil)
{
println("\(error.localizedDescription)")
return
}
if(result != nil)
{
let userId:String = result["id"] as! String
let userFirstName:String? = result["first_name"] as? String
let userLastName:String? = result["last_name"] as? String
let userEmail:String? = result["email"] as? String
println("\(userEmail)")
let myUser:PFUser = PFUser.currentUser()!
// Save first name
if(userFirstName != nil)
{
myUser.setObject(userFirstName!, forKey: "first_name")
}
//Save last name
if(userLastName != nil)
{
myUser.setObject(userLastName!, forKey: "last_name")
}
// Save email address
if(userEmail != nil)
{
myUser.setObject(userEmail!, forKey: "email")
}
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
// Get Facebook profile picture
var userProfile = "https://graph.facebook.com/" + userId + "/picture?type=large"
let profilePictureUrl = NSURL(string: userProfile)
let profilePictureData = NSData(contentsOfURL: profilePictureUrl!)
if(profilePictureData != nil)
{
let profileFileObject = PFFile(data:profilePictureData!)
myUser.setObject(profileFileObject, forKey: "profile_picture")
}
myUser.saveInBackgroundWithBlock({ (success:Bool, error:NSError?) -> Void in
if(success)
{
println("User details are now updated")
}
})
}
}
}
