iOS Parse: Add / Get array of PFUsers

Question

In my app, I have an playlist, which I want to share with another friend. In parse I save the Playlist objects and from the user which created the playlist i save the key: @"user_id".

Now I changed Pointer _User to an array of Users for my sharing future. I already saved in @"user_id" column, an array of users (users which have access to the same playlist) :

[
  {
    "__type" : "Pointer",
    "className" : "_User",
    "objectId" : "teH3s20xxx"
  },
  {
    "__type" : "Pointer",
    "className" : "_User",
    "objectId" : "hgkcjHyi9T"
  },
  {
    "__type" : "Pointer",
    "className" : "_User",
    "objectId" : "K2dZTEKpIX"
  },
  {
    "__type" : "Pointer",
    "className" : "_User",
    "objectId" : "4dbmDuR6LF"
  }
]

Now I need to check if current user is using playlist mentioned above. How can I check if my user is an object in @"user_id" column array?

Could you be a little more clear with what you're asking?

What you're going to want to do is first get the array from that column in parse. Then you want to traverse through it using a for in loop:

for(PFUser *user in arrayYouGotFromParse)
{

if(user == [PFUser currentUser])
//Current user is in the array

}
