twitter分享问题（三）——Required oauth_verifier parameter not provided

使用shareKit做twitter分享，遇到如下错误：

“There was a problem requesting access from Twitter”,打个断点，跟踪到“SHKOAuthSharer.m”的这个函数：

- (void)tokenAccessTicket:(OAServiceTicket *)ticket didFinishWithData:(NSData *)data

看下打印的信息：

TwitterShareDemo[7111:c07] tokenAccessTicket Response Body: <?xml version="1.0" encoding="UTF-8"?>  <hash>    <request>/oauth/access_token</request>    <error>Required oauth_verifier parameter not provided</error>  </hash>

即参数“oauth_verifier”丢失，我去twitter查了下，说是在api 1.0的时候，授权请求时这个参数可有可无，但是到了api 1.0a的时候是必须强制带上的，故需要添加这个参数，修改位置：“SHKOAuthSharer.m”，如下：

- (void)tokenAccess:(BOOL)refresh{if (!refresh)[[SHKActivityIndicator currentIndicator] displayActivity:SHKLocalizedString(@"Authenticating...")];    NSString *oauth_verifier = [self.authorizeResponseQueryVars objectForKey:@"oauth_verifier"];NSString *urlStr = [@"https://api.twitter.com/oauth/access_token" stringByAppendingFormat:@"?oauth_verifier=%@",oauth_verifier];    NSURL *url = [NSURL URLWithString:urlStr];    OAMutableURLRequest *oRequest = [[OAMutableURLRequest alloc] initWithURL:url                                                                    consumer:consumer   token:(refresh ? accessToken : requestToken)                                                                       realm:nil   // our service provider doesn't specify a realm                                                           signatureProvider:signatureProvider]; // use the default method, HMAC-SHA1    //    OAMutableURLRequest *oRequest = [[OAMutableURLRequest alloc] initWithURL:accessURL//                                                                   consumer:consumer//   token:(refresh ? accessToken : requestToken)//                                                                      realm:nil   // our service provider doesn't specify a realm//                                                          signatureProvider:signatureProvider]; // use the default method, HMAC-SHA1    [oRequest setHTTPMethod:@"POST"];[self tokenAccessModifyRequest:oRequest];    OAAsynchronousDataFetcher *fetcher = [OAAsynchronousDataFetcher asynchronousFetcherWithRequest:oRequest                         delegate:self                didFinishSelector:@selector(tokenAccessTicket:didFinishWithData:)                  didFailSelector:@selector(tokenAccessTicket:didFailWithError:)];[fetcher start];[oRequest release];}
