Apple Iphone 6 issue with div id responsive

Apple Iphone 6 issue with div id responsive

I tried to use

<div id="responsive">
Content that is very long in width
</div>

its work for Samsung phone, scrollable left and right to see the content.

But for Iphone 6, the scroll doesn't even appear ( not responsive )

What should I do

I tried added

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

at head and it doesn't work.
