Is this workflow acceptable UI for iPhone?
<p>I have an arrow that points to the bottom for each table cell. When you click on a table cell, the screen doesn't move to another screen. Rather, the bottom picker changes depending on which cell you selected.</p>

<p>Is this workflow acceptable according to Apple, or does it break guidelines?
