ios - Facebook graph-API OAuthException Code:368 Misusing this feature by going too fast -

i try publish comments on pages photos posts using following code :

    nsdictionary *params = @{@"message" :  @"new comment"};      fbsdkgraphrequest *request = [[fbsdkgraphrequest alloc]                                   initwithgraphpath:[nsstring stringwithformat:@"/%@/comments", objectid]                                   parameters:params                                   httpmethod:@"post"];     [request startwithcompletionhandler:^(fbsdkgraphrequestconnection *connection, id result, nserror *error) {         if(error){             nslog(@"error comment %@", [error description]);         }         else{             nslog(@"result comment %@", [result description]);         }      }]; 

it works (worked) when used nsdictionary *params = @{@"message" : @"new comment"};

but when tried use attachment_url parameters value error :

    error =         {        message:"(#1705) there error posting wall";        type:"oauthexception";        code:1705     }; 

i tried make calls using curl , facebook graph-api explorer , same errors. page i'm trying comment on doesn't seem have particular restrictions.

now i'm getting following error :

fbsdkgraphrequesterrorgrapherrorcode=368, com.facebook.sdk:fbsdkgraphrequesterrorparsedjsonresponsekey={ body =     {     error =         {         code = 368;         message = "it looks misusing feature going fast. you've been blocked using it.learn more blocks in center.";         type = oauthexception;     }; }; code = 400; }} 

i guess reach limit of don't know one. suppose know able perform requests on {object-id}/comments again ?

facebook not , not officially post call limits. reason give is: "if using platform responsibility not hit rate limits".

it appears me attempting spam comments multiple objects , of course block this.

so trying do?
