Answer 1

To post a comment on a post, you need a post_id instead of object_id.

So your API call must be-

/{post_id}/comments

(post_id is also a field in the comments table)

Edit:

You must be using a comment plugin and trying to post a comment to that. Unfortunately, facebook don't allows you to do that! (Logical- since most of them are public, to avoid spamming, else anyone could flood comments to that post)

If you check the response here, you'll get:

{
  "error": {
     "message": "(#100) Comments may not be added to a comment plugin", 
     "type": "OAuthException", 
     "code": 100
  }
}

You can test these API call on Graph API Explorer also.

Sahil Mittal : post_id in my case post_fbid which i get above json formate is it you say? – Malefaction

No, change your query. Check this link. Your postid is 1309634065_478409145610921 – Adam

Sahil Mittal :I try your code but still not post comment in the post!! see my edit code pls. – Malefaction

But what's the response this time? – Adam

Sahil Mottal :: When i post comment just print link like 04-01 09:39:47.105: D/Facebook-Util(6675): POST URL: graph.facebook.com/1309634065_758983910781864/comments – Malefaction

Sahil Mittal :: no when i paste this url to browser it give message "Sorry, this page isn't available" – Malefaction

My bad. You are fetching the comments from a url! You didn't mention that in a question! I'll check – Adam

Sahil Mittal : ohh ya brother !! i forgot it for mention i fetch all comments from url !! now see my edit line in above – Malefaction

Sahil Mittal : So using url it is not possible right? – Malefaction

No. Someone posted it as a bug earlier: developers.facebook.com/bugs/164794086987157. But it was closed saying: This functionality was never and is not intended to be available. So, this is not possible! Only the comments on the facebook are accessible via graph api. You can only fetch the comments from url. – Adam

Sahil Mittal Ok bro.. Thnaks for your time and effort !! but thenafter i will accept your answer and +1 vote for that – Malefaction

Great! :) If you find some issue using the facebook APIs you may contact me in case your question not getting attention here – Adam

Using Graph API:

...
if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"]) {
    [[[FBSDKGraphRequest alloc]
      initWithGraphPath:@"post_id/likes"
      parameters: @{ @"like" : @"true"}
      HTTPMethod:@"POST"]
      startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
         if (!error) {
             NSLog(@"It was liked.");
         }
     }];
}
...
