objective c - how to share screenshot to Facebook -


i've done screenshot part, still haven't found solution share screenshot image facebook using fbsdksharephoto. facebook doesn't provide enough references it. can please guide me here?

here screenshot code in case:

cgrect screenrect = [[uiscreen mainscreen] bounds];  uigraphicsbeginimagecontextwithoptions(screenrect.size, no , 0.0f);  cgcontextref ctx = uigraphicsgetcurrentcontext();  [[uicolor blackcolor] set];  cgcontextfillrect(ctx, screenrect);    uiwindow *window = [uiapplication sharedapplication].keywindow;    [window.layer renderincontext:ctx];  uiimage *screengrab = uigraphicsgetimagefromcurrentimagecontext();  uigraphicsendimagecontext();

i believe want fbsdksharephotocontent , fbsdksharedialog. need setup content photo(s):

uiimage *screengrab = uigraphicsgetimagefromcurrentimagecontext(); fbsdksharephotocontent *content = [[fbsdksharephotocontent alloc] init]; content.photos = @[[fbsdksharephoto photowithimage:screengrab usergenerated:yes]];  // assuming self implements <fbsdksharingdelegate>  [fbsdkshareapi sharewithcontent:content delegate:self];
