title: How to use YouTube API V3?
body: <p>I'm trying to figure out how to use the new YouTube API (Version 3) in my iOS app but I don't know how to do it.
  I did many research about it but what I found is all examples and codes for older API so they are not valid.
  Til now I did understand that for using the new API you have to create a Project in Google Developer Console (and I did it)... but then they send you to a page with some code on it but I really don't understand how to use it. <a href="https://code.google.com/p/google-api-objectivec-client/" rel="noreferrer">link to google api page</a>
  What I need to know is how to retrieve some informations from a given URL of a YouTube video, the informations I need are total number of "likes" and total number of "views"... with API 2 it was very simple to do it... but now I really don't know where to begin...
  Is there someone that please can explain how to achieve this with maybe some examples and some code?
  I'm pretty sure that a lot of people will benefit from this.</p>
