title: Unable to Login as Different User After Logging out of iOS application
body: <p>So here is my problem. I log in to my application, then log out of my application, but when I try to log in again, I get the screen in the link below.</p>
  
  <p><a href="http://i.stack.imgur.com/evN71.png" rel="noreferrer">Login Screen</a></p>
  
  <p>As you can see, I don't get the opportunity to login with another user, which is what is intended. </p>
  
  <p>What I tried to do was logout and then clear all the cookies in the logout using these following methods:</p>
  
  <pre><code> @IBAction func logout(sender: AnyObject) {
  
      //Logged out here
      let loginManager = FBSDKLoginManager()
      loginManager.logOut()
  
     //This is one method I tried 
      let appDomain = NSBundle.mainBundle().bundleIdentifier!
  NSUserDefaults.standardUserDefaults().removePersistentDomainForName(appDomain)
  
  
      //This is another method I tried 
      for key in NSUserDefaults.standardUserDefaults().dictionaryRepresentation().keys {
          NSUserDefaults.standardUserDefaults().removeObjectForKey(key)
      }
  
  
      //And this is the last method I tried
      var cookie: NSHTTPCookie
      var storage: NSHTTPCookieStorage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
  
      for cookie in storage.cookies! {
          var domainName: String = cookie.domain
          var domainRange: Range = domainName.rangeOfString("facebook")
          if domainRange.length &gt; 0 {
              storage.deleteCookie(cookie)
          }
      }
  
  }
  </code></pre>
  
  <p>None of these seemed to solve my problem. The app is in "Development" mode in the Facebook Dev account so it might have something to do with this, but not totally sure. Does someone have any experience with this and know the solution to our problem, as shown in the image above. </p>
