You can finally post to Instagram from other iOS apps
The sharing feature you've wanted for two years is here.
Ever since Apple introduced app sharing extensions in iOS 8, budding iPhone photographers have been wondering where Instagram's extension was. Wouldn't it be nice if you could share a photo from any app, rather than diving into Instagram and choosing from your camera roll? You're getting that chance today: Instagram has quietly introduced a sharing extension to the latest version of its iOS app. So long as you turn on the extension, any app that supports iOS' official sharing method can send a photo Instagram's way. That's a particularly big deal if you're fond of third-party imaging apps, which don't always automatically save pictures to your photo library.
The addition is overdue, to put it mildly. Android users have had this share-from-anywhere luxury for a while, and numerous other photo-focused apps (such as Flickr) have had iOS sharing extensions for a long time. All the same, it's good to see Instagram fill in a missing piece of the puzzle.
