Ideas? 回答1: Found a way by registering to all sub directories of dcim (except the ones that start with a period):

问题 My ultimate goal is to do this programmatically, but as a sanity check I'm trying to just post an uploaded photo (from my computer) to a Facebook page using the Facebook Graph API Explorer. I have the access token and photo_upload and publish_stream permissions. I just don't understand what to do to indicate where the photo is. How can I do it?

问题 I am trying to post a photo to a page that the user does not own. Note that all solutions that I found from other discussion threads require the user to be administrative and get the access_token of a page with *manage_pages* permissions. However, what I want to do is different: Using iOS SDK to upload an image to a page, which has a setting that people can upload images to it. I try several ways, but none of them works.
