Objective C 输出流刷新有问题吗？
你好，我在 Objective C 中遇到了 NSOutputStream 的问题。我的计算机上运行着一个服务器，iPhone 模拟器将数据发送到服务器，服务器应该将其发回。唯一的问题是，当我发送它时，它不会发送文本，直到我退出模拟器，然后服务器才会获取信息。
NSString* toSend = chatField.text;
NSData* sendData = [[NSData alloc] initWithData:[toSend dataUsingEncoding:NSASCIIStringEncoding]];
[outStream write:[sendData bytes] maxLength:[sendData length]];
[chatField setText:@""];
我用它初始化了它
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，我缺少类似于 Java .flush() 方法的东西。有人知道问题所在吗？
谢谢！
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:@""];
I initialized it with
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];
It seems to me like I'm missing something akin to the Java .flush() method. Does anyone know the problem?
Thanks!

在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":
