Login and Logout with Facebook account - ios

Question

I want to add login with Facebook account to my IOS app. I tried installing FacebookCore pod and FacebookLogin pod. My login action was successful but when I try to logout then login again, browser used the previous logged in account. Here is my code for login and logout action:
override func viewDidLoad() {
super.viewDidLoad()
let loginButton = LoginButton(readPermissions: [ .publicProfile ])
loginButton.center = view.center
//adding it to view
view.addSubview(loginButton)
loginButton.delegate = self
}
func loginButtonDidCompleteLogin(_ loginButton: LoginButton, result: LoginResult) {
print("logged in")
self.loginButtonClicked()
}
func loginButtonDidLogOut(_ loginButton: LoginButton) {
print("logged out")
AccessToken.current = nil
UserProfile.current = nil
FBSDKLoginManager().logOut()
}
//when login button clicked
func loginButtonClicked() {
let loginManager = LoginManager()
loginManager.loginBehavior = .web
loginManager.logIn(readPermissions: [.publicProfile], viewController: self, completion: {loginResult in
switch loginResult {
case .failed(let error):
print("loginnnnnn errrooorrr",error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
self.getFBUserData()
}
})
}
//function is fetching the user data
func getFBUserData(){
if((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil){
self.dict = result as! [String : AnyObject]
self.isLogin = true
print(result!)
print(self.dict)
}
})
}
}
How to login with another account?

I had similar issue, I was receiving
you previously logged in to [app name] with Facebook. Would you like
to continue?
every time I wanted to log in into my app even after logout.
I solved it by using of Facebook native app (ver. 177).
You can 'log out' from your app here:
Menu Tab -> Settings -> 'Apps and Websites' -> 'Logged in with Facebook' -> Active -> select app -> tap Remove
