It looks like UIWebView snarfs up all the gestures by default. I had a project 
where I needed to "see" a tap on the web view without otherwise disrupting the 
normal behavior. I ended up creating a UITapGestureRecognizer, set its delegate 
to "self", and then implemented 
-gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:, always 
returning YES. Perhaps something similar would work for you.
