-(IBAction)facebookLoginClick:(id)sender {

FBSDKLoginManag         


        

Answer 1

For me in Objective-C following worked

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
if ([FBSDKAccessToken currentAccessToken]) {
             [login logOut];
        }

and issue was user was trying to login as another user as suggested by @Vineeth Joseph
