关于目标C输出流冲洗的问题? [英] Issue with objective C outputstream flushing?

问题描述

您好，我在Objective C中遇到NSOutputStream问题.我的计算机上正在运行服务器，iPhone仿真器将数据发送到服务器，服务器应将其发送回去.唯一的问题是，当我发送它时，直到我退出仿真器，它才发送文本，然后服务器才获取信息.

Hello I'm having an issue with an NSOutputStream in Objective C. I've got a server running up on my computer and the iPhone emulator sends data to the server and the server should send it back. The only issue is, when I send it, It's not sending the text until I exit out of the Emulator, and only then does the server get the information.

NSString* toSend = chatField.text;
NSData* sendData = [[NSData alloc] initWithData:[toSend dataUsingEncoding:NSASCIIStringEncoding]];
[outStream write:[sendData bytes] maxLength:[sendData length]];
[chatField setText:@""];

我用

CFReadStreamRef reader;
CFWriteStreamRef writer;
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)ipField.text, 5000, &reader, &writer);
inStream = (NSInputStream *)reader;
outStream = (NSOutputStream *)writer;
[inStream setDelegate:self];
[outStream setDelegate:self];
[inStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[inStream open];
[outStream open];

在我看来，我好像缺少类似于Java .flush()方法的东西.有人知道这个问题吗?

It seems to me like I'm missing something akin to the Java .flush() method. Does anyone know the problem?

谢谢！

推荐答案

在您发送到服务器的消息末尾添加"\ r \ n":

At the end of the message you are sending to the server add "\r\n":

NSString* toSend = [NSString stringWithFormat:@"%@\r\n", chatField.text];
