With it, you can at last send pieces of content to Messenger without leaving other apps. Using iOS 8’s standard Share sheet, it’s simple to share photos, videos and links directly with Messenger contacts, without leaving context of the app you’re currently using.
Before it can be used, the extension must be enabled first.
To do this, I just invoke the Share sheet in any app like, say, Photos. Next, I’d swoosh the top row of icons by swiping to the left until the “More†option came into view.
As illustrated on the top screenshot, tapping “More†brings up the interface which lets me flip the switch next to “Messenger†to ON. Furthermore, I can optionally drag “Messenger†further up for quicker access.
