我正在尝试使用SLRequest类从Twitter Streaming API中提取数据。 当我使用下面的代码中记录的端点和参数“挂起” 并且没有打印JSON数据时。我正在使用基于来自twitter dev 网站https://dev.twitter.com/docs/streaming-apis/parameters#with的示例的端点。我正在请求 在特定位置的推文。Twitter Streaming端点不能与SLRequest对象一起使用
当我使用此代码使用REST API查询我的时间线时(包含代码和请求,但 注释掉了),程序没有挂起,我得到一个有效的响应。
我需要使用流式API访问数据时需要实现代码中的其他内容吗?需要进行哪些额外的修改或更改?

if (granted == NO) {
NSLog(@"-- error: %@", [error localizedDescription]);
