touch multi UIViews
<p>There are a series UIViews arranged very close.</p>

<p><img src="http://www.mobilepanda.com/questiontouch.png" alt="alt text"></p>

<p>I hope when my finger touches some of them, my app can detect which UIView touched.
Maybe one or two or three.(because the displayed parts of each UIView are too thin).
I hope to get the middle x value of the touch, then spread the UIView where the middle x value locates and the UIViews near it.

<p>My way is put a transparent UIView over all these UIView to detect the touch event.
I am not sure if this is ok? or there is any better solution.(for example, make each UIView has the capability to detect the touch, mix and decide which UIView is touched.</p>

<p>Welcome any comment</p>

<p>Thanks</p>
