Pickerview within enclosing view
<p>using iphone sdk 4.0. I have added a UIPickerView to a view. I want the UIPickerView 
to be NON transparent ( as it is) but i want the background view to have an alpha of 0.3.</p>

<p>THis is so that the upper portion of the view (which is full size screen) is see through
and the lower portion which has the picker is solid. However when i set the alpha for the 
background view its affecting the pickerview and making that seethrough.</p>

<p>Anyone know how to do this?</p>

<p>Thanks</p>
