How does iOS open PDF's in the Mail app?

Does the Mail app on iOS use UIDocumentInteractionController() to open a pdf from within Mail in iOS 10??

Solution

  • It's hard to know for sure, but it probably uses either that or UIWebView.

    EDIT: If you want to share a PDF too, then you should be able to do that using UIActivityViewController with its activityItems just set to the PDF. See this question.
