Objective-c get object that was called selector
<p>Is it possible to get id pointer to object which was called selector inside function with no sender argument?</p>

<pre><code>- (void)didSomeThing {//delegate method may call from any object
//how to get sender = someObj?
id sender = ??
} 
....
//calling
[someObj didSomeThing];
...
</code></pre>
