Hello everyone, I want show per page pdf in portait mode and display two pages when rotate to landscape mode on ipad . I had search on internet and can't find any solution. I thought two possible way.

1.Using webview but I don't know how to display two page in one webview in a webview.

2.Using CGPDF API read from two page and merge to one pdf file. But I think this may be very slow and not sure if this could do it .

or any other way could solve this problem? Thanks!!
