Question

I use Facebook 3.1 and try comment on a particular post. I have used the following code. I have used the below mentioned permissions also while creating session:

read_stream,offline_access,publish_stream,share_item

The code:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"This is my comment", @"message", nil];
NSString *string=[NSString stringWithFormat:@"https://graph.facebook.com/153125724720582_184234384932460/comments?access_token=%@",appDelegate.session.accessToken];
[FBRequestConnection startWithGraphPath:string
                     parameters:params
                     HTTPMethod:@"GET"
                     completionHandler:^(FBRequestConnection *connection,
                       id result,
                       NSError *error) {
                         if (error) {
                           NSLog(@"Error: %@", [error localizedDescription]);
                         } else {
                           NSLog(@"Result: %@", result);
                         }
}];

Response  : 
Result: {
    comments = 1;
    id = "https://graph.facebook.com/153125724720582_184234384932460/comments";
}

But my message is not updated on commented post id.

Same code with Post request also I have tried but Response is:

Result: {
    "FACEBOOK_NON_JSON_RESULT" = false;
}

You should use an HTTP POST and make sure that the user has granted publish_stream permissions.

You should copy and paste the API call (and the access token) into the Graph Explorer to test your call out.

(Also use the access_token debugger to make sure the permission is there)
