- view:
The view that contained the touch.
Return Value

Discussion
Use this method to get additional precision for a touch’s previous location (when available). Do not use the returned point for hit testing. In some cases, hit testing can indicate that the touch is within a view, but hit testing against the more precise location may indicate that the touch is outside of the view.
