iOS Parse: Add / Get array of PFUsers -

in app, have playlist, want share friend. in parse save playlist objects , user created playlist save key: @"user_id".

now changed pointer _user array of users sharing future. saved in @"user_id" column, array of users (users have access 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 need check if current user using playlist mentioned above. how can check if user object in @"user_id" column array?

what you're going want first array column in parse. want traverse through using in loop:

for(pfuser *user in arrayyougotfromparse) {  if(user == [pfuser currentuser]) //current user in array  }
