I get 2 fingers zoom on android but not on ios

I was struggling with having 2 finger events on touch devices.Finally I
removed all the meta tags from my Html and it made the Android device to
work , however I still have problem with iPad.
I read all the other threads about zoom in and tried different variation
of this meta tag :
<meta name="viewport" content="
user-scalable=yes,
width=device-width,
initial-scale=1.0, maximum-scale=3.0, minimum-scale=0"/>
but none of them helped have scroll on iPad.
when I have this :
<meta name="viewport" content="user-scalable=yes" />
I get zoom on Android but still no 2 finger pinch or scroll on iPad.
I appreciate any help or suggestion on that.
