I was going through our codebase and identified that we are not checking the orientation of documents during printing. It is automatically taking default orientation as Portrait, even when I am passing the landscape document.

So, I want to know, is there any function in Objective-C that helps me in recognizing the orientation of document while printing.

Note: I am not talking about device orientation but the orientation of the document that has to be printed

A PDF file has the orientation? A Word file has it, too? – El Tomato Dec 21 '20 at 05:09
That's easy. You just need to get the page size. Btw if your question is about Objective-C why did you tag your question with Swift? – Leo Dabus Dec 21 '20 at 05:13
@ElTomato ,I didn't get you. To be more specific I want to recognize the orientation of documents before printing. – Paras Saini Dec 21 '20 at 05:15

@LeoDabus, Thanks and I readjusted tags(PS: This is my first post that's why i did that,i will keep in mind for the next time) – Paras Saini Dec 21 '20 at 05:19
For PDFs it is the same approach. Get the page dimensions and just check if the height is greater than the width is portrait otherwise is landscape. – Leo Dabus Dec 21 '20 at 05:21
Note that there is no guarantee that all pages in a PDF will have the same orientation. – Leo Dabus Dec 21 '20 at 05:24
