@selector to a function in a separate class
<p>If I have a function that is defined in class Foo, and my class Bar has a reference to class Foo, can I use the @selector to call that function?  Something like</p>

<pre><code>@selector([Foo someFunctionInFoo:])
</code></pre>

<p>I have only used the @selector to call functions in the same class.  I tried doing something similar to the above code, but it didn't work and I wasn't sure if it was even possible.  Thanks.</p>
