Ios: can I disable the elastic bounce effect?

I tried cocoon.io and phonegap. Both of them give me the same visual result on ios platform (all is ok on android btw). When I try to drag the screen on Iphone or Ipad I can see gap on the top or on the bottom like this:

• look like web page in safari on mobiles

How to turn it off?

For all who also faced with this issue:

add this in config.xml:

preference name=“DisallowOverscroll” value=“true”/

preference name=“UIWebViewBounce” value=“false” /

and also, better for games to add this in index.html:

{

overflow: hidden;

height:100%;

}
