[pdfcontroller.emailbuttonitem  setsendoptions:pspdfdocumentsharingoptioncurrentpageonly|pspdfdocumentsharingoptionallpages|pspdfdocumentsharingoptionflattenannotations|pspdfdocumentsharingoptionembedannotations]; 

that want make work latest version. have seen in new version have like:

pspdfdocumentsharingviewcontroller *sharingvc = [[pspdfdocumentsharingviewcontroller alloc] initwithdocument:document visiblepages:nil allowedsharingoptions:pspdfdocumentsharingoptioncurrentpageonly|pspdfdocumentsharingoptionallpages|pspdfdocumentsharingoptionflattenannotations|pspdfdocumentsharingoptionembedannotations]; 

but don´t know how apply pspdfviewcontroller object (pdfcontroller).

also know how move new version:

pdfcontroller.emailbuttonitem.mailcomposeviewcontrollercustomizationblock = ^(mfmailcomposeviewcontroller *mailcontroller) { [mailcontroller setsubject:@"information"]; };

i have seen in documentation:

api: removes mailcomposeviewcontrollercustomizationblock. use pdfviewcontroller:shouldshowcontroller:embeddedincontroller:options: delegate.

but no idea how apply it.

any help?

thanks!
