iphone SDK: How can I get the current selected row for UIPicker?
<p>How can I get the current selected row for UIPicker?</p>

<p>I want to use it to get at the associated string. Like this. The problem is I do not know how to get the row.</p>

<pre><code>//need to get currently selected row
 NSString *strPeriodSelection = [arrayRecurChoices objectAtIndex:periodPicker.row???];
</code></pre>

<p>Thanks in advance.</p>
