title: Social media and my own login/register in app
body: <p>I'm started developing apps for iOS 4 months ago, and I'm getting the hang of it. Now I want the take it to the next level with login and register options in my new app. But I don't really know the right approach for this.</p>
  
  <ul>
  <li>When using the social media api's (Facebook/Twitter) and the user uses this to register and login. Do I need to save this register in my own sql database? So I can hook data to the user like, how many clicks did the user do on stuff? Or how is this handled?</li>
  <li>Can this be the database where I can store my own register/login options for users that don't have social media or does not want to use it for my app.</li>
  <li>All requests from and to my server, are they fully secured when using https? Or how do I need to secure this so user can not sniff the network for the information (hackers and stuff, you'll never know lol)</li>
  </ul>
  
  <p>I did some research but I can not find stuff about this, probably because I'm dutch, and do not really know how to formulate my questions in google about this stuff. If anyone can pass me some tutorials and information about this topic, this would be really helpful!</p>
  
  <p>Thanks in advance!</p>
