So I noticed that the FBSDK is affecting a lot the storyboard, so I'll present you what I want to do and when I open up the app why it presents the SIGABRT.
Here is want I want to perform:
func switchStoryboard() {
self.performSegue(withIdentifier: "LoginConnection", sender: self)
}
This is how I want it to be performed:
override func viewDidLoad() {
super.viewDidLoad()
if FBSDKAccessToken.current() != nil {
print("User is logged in")
}
else {
self.switchStoryboard()
}
Where the problem is supposed to be located at:
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
if (error != nil){
print(error)
return
}
FBSDKGraphRequest(graphPath: "/me", parameters: ["fields": "id, name, email"]).start { (connection, result, err) in
if (error != nil){
print("Failed to get graph request", err)
return
}
print(result)
}
Well, I have no clue. I tried to debug, everything seems ok but it confuses me a lot, hopes someone here had the same mistake and could help me with this, thanks a lot.
fixed with:
if((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
print(result)
}
self.switchStoryboard()
print("user is not signed in")
})
}
problem is that the function of self.switchStoryboard() is not working as well as the both print's

I am using a custom button for my Facebook login. When I click the button a webpage inside the app opens the facebook page with login with app or email/phone. I click open in app, and go through the process. After that process, I get redirected to my app, but the webpage still appears, and is not dismiss.
#IBAction func loginFacebookAction(sender: AnyObject) {//action of the custom button in the storyboard
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self) { (result, error) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result
if(fbloginresult.grantedPermissions.contains("email"))
{
self.getFBUserData()
}
}
}
}
func getFBUserData(){
if((FBSDKAccessToken.currentAccessToken()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error == nil){
//everything works print the user data
print(result)
}
})
}
}
I have done FB login from my app in Swift 3. Now, I need to fetch profile picture from Facebook. Plzz any one who could give me the solution in Swift 3 ??
Please try this one.
let login = FBSDKLoginManager()
login.logIn(withReadPermissions: ["email"], from: self) { (result, error) -> Void in
if (error != nil) {
self.view.makeToast("Error")
}
else if (result?.isCancelled)! {
self.view.makeToast("Cancel")
}
else {
if (FBSDKAccessToken.current() != nil) {
FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,interested_in,gender,birthday,email,age_range,name,picture.width(480).height(480)"]).start(completionHandler: { (connection, result, error) -> Void in
print(result)
})
}
}
}
I'm trying to pass a property to my next VC using prepareforSegue. It is called, however my other VC does not load.
Original
#IBAction func onSignupPressed(sender: AnyObject) {
FBSDKLoginManager().logInWithReadPermissions(permissions,
fromViewController: self) { result, error in
guard error == nil else { print("Login Error"); return }
guard result.grantedPermissions.contains("email") else {
print("No Email Permissions"); return }
self.getFBUserData()
dispatch_async(dispatch_get_main_queue()) {
self.performSegueWithIdentifier("loginSegue", sender: self)
}
}
}
I've been able to get the next VC showing by doing calling my doLogin function below. And there I instantiate a VC from the storyboard and present it. I believe it is due to the timing of the Facebook login window that pops up and closes. I searched for a delegate method, but have not found anything
#IBAction func onSignupPressed(sender: AnyObject) {
FBSDKLoginManager().logInWithReadPermissions(permissions,
fromViewController: self) { result, error in
guard error == nil else { print("Login Error"); return }
guard result.grantedPermissions.contains("email") else {
print("No Email Permissions"); return }
self.getFBUserData()
dispatch_async(dispatch_get_main_queue()) {
self.performSegueWithIdentifier("loginSegue", sender: self)
}
}
}
func getFBUserData(){
let params = "id, name, first_name, last_name, picture.type(large),friends, email, birthday, work, photos, education, location, hometown, religion, likes, about"
if((FBSDKAccessToken.currentAccessToken()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields":params]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error == nil){
//everything works print the user data
print(result)
let resultdict = result as? NSDictionary
self.user = Mapper<User>().map(result)
self.doLogin()
}
})
}
}
func doLogin() {
let successVC = self.storyboard?.instantiateViewControllerWithIdentifier("LoginSucessViewController")
self.presentViewController(successVC!, animated: true, completion: nil)
}
Very silly mistake! Didn't realize I could simply set the property of instantiating the VC!
func doLogin() {
let successVC = self.storyboard?.instantiateViewControllerWithIdentifier("LoginSucessViewController") as! LoginSucessViewController
successVC.currentUser = user
self.presentViewController(successVC, animated: true, completion: nil)
}
my name is Vincent and I need your help !

No problem to login or logout with the Facebook SDK ... BUT
When I start my app, no access token and when i click on the Login button, it prints me an accessToken, then I logout.
How to get the accessToken when the app starts ?
import UIKit
import FBSDKCoreKit
import FBSDKLoginKit
class HomeViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
getUserStatuts()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
// MARK -> Facebook Connect
func loginToFacebook() {
if let fbToken = FBSDKAccessToken.currentAccessToken() {
print("Acces token : \(fbToken)")
loginManager.logOut()
print("Logout")
} else {
print("Login")
loginManager.logInWithPublishPermissions(publishPermissions, fromViewController: nil, handler: {
(result:FBSDKLoginManagerLoginResult!, error:NSError!) -> Void in
if error == nil {
self.getUserData()
} else {
print(error.localizedDescription)
}
})
}
}
func getUserData() {
let readPermissions = ["public_profile", "email", "user_friends", "user_birthday"]
let parameters = ["fields": "id, first_name, last_name, name, birthday, picture.type(large)"]
let request = FBSDKGraphRequest(graphPath: "me", parameters: parameters)
request.startWithCompletionHandler({
(connection, result, error) -> Void in
if error == nil {
// display info
}
})
}
In the login function you want to implement the
let fbLogin = FBSDKLoginManager()
fblogin.logout()
the fblogin.logout() must be implemented before fbLogin.logInWithReadPermissions(["email"], fromViewController: self) { (facebookResult, facebookError) in
if facebookError != nil { ` to clear any access tokens from previous login.
I added FBSDK 4.7 to my swift app and when it opens the safari view controller to login, and I try to tap "Done" without inputting anything into the email/password fields, the app breaks. It spits out "fatal error: unexpectedly found nil while unwrapping an Optional value"
How do I handle this error?
Current login code:
if let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager(){
fbLoginManager.logInWithReadPermissions(["email"],fromViewController:self,
handler:{(result:FBSDKLoginManagerLoginResult!,error:NSError!) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result
if(fbloginresult.grantedPermissions.contains("email"))
{
print("Logged in successfully")
self.getFBUserData()
//fbLoginManager.logOut()
}
}
else{
print("HELPPPPPPPPPP")
}
})
}
No need to assign the types of variable (result, error) :
Here is working code with Facebook 4.7 SDK | Swift 2 | Xcode 7.
#IBAction func btnFBLoginPressed(sender: AnyObject) {
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.Web
fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self, handler: { (result, error) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result
if fbloginresult.grantedPermissions != nil { //Here we have to check that the set contains value or not
if(fbloginresult.grantedPermissions.contains("email"))
{
self.getFBUserData()
fbLoginManager.logOut()
}
}
}
})
}
func getFBUserData(){
if((FBSDKAccessToken.currentAccessToken()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error == nil){
print(result)
}
})
}
}
We have to check the grantedPermissions's Set is nil or not.
if fbloginresult.grantedPermissions != nil { //Here we have to check that the set contains value or not
