                             if ([responseDictionary objectForKey:@"errors"]) {

                                     [self showAlert: @"Twitter": [[[responseDictionary objectForKey:@"errors"] objectAtIndex:0] objectForKey:@"message"]];
                                 });
                             }
                         }
                     } else {
                         // responseDictionary is nil
                         dispatch_async(dispatch_get_main_queue(), ^{
                             [self showAlert: @"Twitter": @"Unable to authenticate you"];
                         });
                     }
                 }];
            }
        } else {
            //Failed
            NSLog(@"error getting permission %@",error);
            dispatch_async(dispatch_get_main_queue(), ^{
                [self showAlert: @"No Twitter Account Detected": @"Please go into your device's settings menu to add your Twitter account."];
            });
        }
    }];
}

上面是我的代码，下面是我控制台上的输出。

输出： 

Twitter HTTP response: 401
Response: {
    errors =     (
                {
            code = 32;
            message = "Could not authenticate you";
        }
    );
}

我想从 Twitter 获取用户数据，例如名字、姓氏、个人资料图片、登录 ID。

提前致谢...
