I am displaying a Google map on a mobile webpage with the following:
<iframe width="100%" height="70%" src="https://maps.google.com/maps?q=loc:'.$latlong.'+('.$balloon.')&t=h&&iwloc=1&z=17&output=embed"></iframe>';
It works fine on Android but on iPhone the map is the full height of the screen instead of 70%. That makes it impossible to scroll down the page because when you try to drag the page, all that you do is drag the map view.
Is that a known problem and is there any solution please?
