CFReadStreamCreateForHTTPRequest(kCFAllocatorDefault, cfrequest); inputStream = (__bridge_transfer NSInputStream...CFRelease(bodyData); CFRelease(requestBody); CFRelease(requestMethod); } 当runloop发出请求，有响应包返回时，会调用NSInputStream...buffer[16 * 1024]; UInt8 *buf = NULL; unsigned long length = 0; NSInputStream...*inputstream = (NSInputStream *) aStream; NSNumber *alreadyAdded = objc_getAssociatedObject...是底层的socket通信，还会对上层协议http进行头部完整验证，但后来一想，这个stream是由CFReadStreamCreateForHTTPRequest创建的，这可能并不是简单的NSInputStream

NSJSONWritingOptions)opt error:(NSError **)error; 将JSON数据写入到输出流，返回的是写入流的字节数 + (id)JSONObjectWithStream:(NSInputStream
readonly, nullable) NSString *protocolString; // 输入流 用来向外设发送数据 @property (nonatomic, readonly, nullable) NSInputStream
这里扩展一下，AFMultipartBodyStream类中声明了NSInputStream类型的对象。...而NSInputStream是文件的读取流,是将本地的文件读取到内存中去 ，与之对应的就是NSOutputStream，文件的写入流，将内存中的文件数据写入到文件中。
CFHttpMessageURLProtocol () { NSMutableURLRequest *curRequest; NSRunLoop *curRunLoop; NSInputStream
比如在run loop上schedule一个NSInputStream，你需要像下面这样： [iStream setDelegate:self]; [iStream scheduleInRunLoop:
用于POST请求 @property (nullable, copy) NSData *HTTPBody; //设置http请求体的输入流 @property (nullable, retain) NSInputStream
核心思路 用NSInputStream读入原始H.264码流，用CADisplayLink控制显示速率，用NALU的前四个字节识别SPS和PPS并存储，当读入IDR帧的时候初始化VideoToolbox

typedef void (^AFURLSessionDidFinishEventsForBackgroundURLSessionBlock)(NSURLSession *session); typedef NSInputStream
mainRunLoop]，不是[NSRunLoop currentRunLoop]； - (void) session:(MCSession *)session didReceiveStream:(NSInputStream
传输数据（指令） 创建EASession、打开输入、输出通道 App和外围设备通讯、数据传输，靠的是NSInputStream和NSOutputStream对象，而这两个对象是EASession的两个属性
AFMultipartBodyStream *bodyStream; 其中，AFMultipartBodyStream是这样定义的： @interface AFMultipartBodyStream : NSInputStream...; @property (nonatomic, assign) unsigned long long bodyContentLength; @property (nonatomic, strong) NSInputStream
