Unable to lock orientation for fixed layout ePub (*.epub) files with the latest versions of iOS (version 9.2.1) and iBooks (version 4.6).
In the OPF file, the following properties were added:
<meta property="rendition:layout">pre-paginated</meta>
<meta property="rendition:spread">none</meta>
<meta property="rendition:orientation">landscape</meta>
And iBooks specific:
<meta property="ibooks:ipad-orientation-lock">landscape-only</meta>
<meta property="ibooks:iphone-orientation-lock">landscape-only</meta>
But the orientation changes for each cases.
Thanks
