Getting username and profile picture from Facebook iOS 7

Question

I have read a lot of tutorials about getting information from Facebook, but I have failed so far. I just want to get username and profile picture from Facebook.

Answer 1

Make the following Graph request:

/me?fields=name,picture.width(720).height(720){url}

And you get really large and cool profile picture:

{
  "id": "459237440909381",
  "name": "Victor Mishin", 
  "picture": {
    "data": {
      "url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-xpf1/t31.0-1/c628.148.1164.1164/s720x720/882111_142093815957080_669659725_o.jpg"
    }
  }
}

P.S. /me?fields=picture.type(large) doesn't do it for me.
