Having trouble programming streams

Question

So here\'s the issue: The stream isn\'t writing at the right time and is unable to get a response from my server. I know I\'m writing the right data, because when I stop th

Answer 1

You are reading with this:      

[asyncSocket readDataToData:[GCDAsyncSocket CRLFData] withTimeout:-1 tag:2];

Which expects a CRLF as a separator of the stream. But I don't see where you append it to your JSONRequestData. So modifying your JSONRequestData to be mutable, like so:

NSMutableData *JSONRequestData;

And then before this line:

 

[asyncSocket writeData:JSONRequestData withTimeout:-1 tag:1];

Add this:

[JSONRequestData appendData:[GCDAsyncSocket CRLFData]];

Answer 2

When sending short chunks of data always flush the buffer after each write which you want to have an immediate effect.
I don't see you doing that in your code.
If you don't do it then the buffer will be flushed only when it is full or the stream is closed.
