NSOutputStream冲洗 [英] NSOutputStream flushing

问题描述

我正在使用iPhone应用程序，并且想使用:

I'm working on an iPhone App and wanted to use:

CFStreamCreatePairWithSocketToHost(NULL, url, port, &serverReadStream, &serverWriteStream);

然后使用:

[serverWriteStream write:[sendData bytes] maxLength:[sendData length]];

我想发送5字节的小包以获取实时更新.

I want to send small Packages of 5 Bytes to get realtime updates.

我的问题是，流仅在缓冲区已满时才发送数据.因此，我需要某种冲洗方法或告诉流立即发送数据.

My problem is now, that the stream only sends data when the buffer is full. So I need some kind of a flush method or tell the stream to immediately send the data.

搜索此问题的结果是找到似乎属于未记录API的"TCP_NODELAY"(我不能将其用于AppStore，如果我输入错误，请纠正我)，即使我可能被允许使用它，我会不得不改变流的创建，对吧?

Searching for this problem ended in finding 'TCP_NODELAY' which seems to belong to the undocumented API ( which I mustn't use for AppStore, correct me if im wrong pls ) and even if I might be allowed to use it, I would have to change the creation of the streams, right?

推荐答案

可可NSOutputStream发送到连接

只需在字符串中添加一个行尾"("\ n").为我工作.

Just add an "end of line" ( "\n" ) to your string. work for me.
