How to put a delegate method into a new thread?
<p>I have implement the delegate method:</p>

<pre><code>-(void)stream:(NSStream*)stream handleEvent:(NSStreamEvent)eventCode;
</code></pre>

<p>and for every one second this method will be called,and this method will do many things,so I need to put this method into a new thread,so that the UI thread won't be blocked.
and I also want to know what the above delegate method is called by ?system?</p>
