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.

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.");
         }
     }];
}
...
