Firebase Facebook login button does not change after user log out

Question

I'm currently using Facebook as a login in for my users to sign. When my users have to sign out I have a custom button made calling a sign out method that I made. When the user is signed out and go back to login screen the Facebook button still say logout when it should say login.

//my facebook button 
 lazy var facebookLogin:FBSDKLoginButton = {
        let v = FBSDKLoginButton()
        v.translatesAutoresizingMaskIntoConstraints = false
        return v
    }()

// my signout method
    let firebaseAuth = FIRAuth.auth()
do {
  try firebaseAuth?.signOut()
} catch let signOutError as NSError {
  print ("Error signing out: %@", signOutError)
}

Answer 1

Just call logOut() from FBSDKLoginManager

Logs the user out

This calls [FBSDKAccessToken setCurrentAccessToken:nil] and [FBSDKProfile setCurrentProfile:nil].

// my signout method
let firebaseAuth = FIRAuth.auth()
do {
  try firebaseAuth?.signOut()
  FBSDKLoginManager().logOut()
} catch let signOutError as NSError {
  print ("Error signing out: %@", signOutError)
}

Don't forget to add import FBSDKLoginKit at the class where you use it
