Unrecognized selector with array objects.
<p>The NSImageView objects once in the array become strings. How to I convert them into NSImageView to avoid unrecognized selector error generated by the last line?</p>

<pre><code>NSArray *array = [NSArray arrayWithObjects: @"chip1”, @"chip2” nil],
for (id image in array) {
[image setImage: nil];
}
</code></pre>
