gtm-oauthとgtm-http-fetcherで添付するときのメモ

（１）バイナリ以外の項目

GTMMIMEDocument *doc = [GTMMIMEDocument MIMEDocument];

// keywordはNSString
 NSMutableDictionary *headers
 = [NSMutableDictionary dictionaryWithObject:@"form-data; name=\"keyword\"" forKey:@"Content-Disposition"];
    [doc addPartWithHeaders:headers body:[keyword dataUsingEncoding:NSUTF8StringEncoding]];

// entryTextはNSString
headers = [NSMutableDictionary dictionaryWithObject:@"form-data; name=\"status\"" forKey:@"Content-Disposition"];
 [doc addPartWithHeaders:headers body:[entryText dataUsingEncoding:NSUTF8StringEncoding]];

（２）リクエストにoauth認証の情報を追加するのは一番最後送信直前にする

NSMutableURLRequest *request
 = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"送信先URL"]];
[request setHTTPMethod:@"POST"];
// ：：
// いろいろ
// ：：
//authはGTMOAuthAuthentication
[auth authorizeRequest:request];
GTMHTTPFetcher *fetcher = [GTMHTTPFetcher fetcherWithRequest:request];
[fetcher setPostStream:stream];
[fetcher beginFetchWithDelegate:self
                      didFinishSelector:@selector(送信したあと)];
