我正在 iOS 上编写一个简单的应用程序，并且我正在尝试使用 RESTFull Web 服务为了获得一些技巧并获得一些知识，我首先从 twitter 开始，而不使用 ios 集成库，但我总是在 Auth 上备货。

任何工作示例或链接将不胜感激，因为提醒 twitter 不是我的最终目标

例如，这是我的代码之一，基于 RestKit 和 AFOAuth1Client ：

    NSURL *url = [NSURL URLWithString:@"https://api.twitter.com"];

AFOAuth1Client * twitterClient = [[AFOAuth1Client alloc] initWithBaseURL:url key:kCLIENTID secret:kCLIENTSECRET];

[twitterClient authorizeUsingOAuthWithRequestTokenPath:@"oauth/request_token"
                                 userAuthorizationPath:@"oauth/authorize"
                                           callbackURL:[NSURL URLWithString:@"af-twitter://success"]
                                       accessTokenPath:@"oauth/access_token"
                                          accessMethod:@"POST"
                                                 scope:@""
                                               success:^(AFOAuth1Token *token, id responseObject) {
                                               }
                                               failure:^(NSError *error) {

                                               }];

如您所见，它不起作用：

“401 Unauthorized”表示您的凭据不正确。因此，请检查您的 API 密钥。

尝试这个：

[twitterClient authorizeUsingOAuthWithRequestTokenPath:@"/oauth/request_token"
                                     userAuthorizationPath:@"/oauth/authorize"
                                               callbackURL:[NSURL URLWithString:@"instantshare-twitter://success"]
                                           accessTokenPath:@"/oauth/access_token"
                                              accessMethod:@"POST"
                                                     scope:nil
                                                   success:^(AFOAuth1Token *accessToken, id responseObject) {
                                                       [twitterClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
                                                   } failure:^(NSError *error) {
                                                       NSLog(@"Error: %@", error);
                                                   }];

请注意这一行scope:nil，由于某种原因，它不适用于空字符串。

除其他事项外，请检查您在 twitter 中的应用程序设置。我不确定是否是这种情况，但我启用Allow this application to be used to Sign in with Twitter并将回调 URL设置为一些随机的有效 url
