You can also do quite a lot with URL Schemes but more apps need to implement support and publish their requirements.
There is also the X-URL-Callback spec which could be implemented by more apps. Google is using this spec on iOS.

Finally, let's get away for guessing about what Apple might be doing. It was easy enough to search "iOS open in" to find this support to support this feature and it had been around a few years. There's no reason to suggest that Apple is copying Android on this feature.
1. Why is this happening only in iMessage?
2. Why does iMessage offer so many options to open a picture in? And why are apps that don't share photos included in this list?
3. Why can't iMessage share photos to iCloud?
4. Is iMessage broken? What makes iMessage different from other Apple apps included in iOS?
5. Why isn't Apple leading the charge and actively pushing this much needed interaction?
I think Android's approach is much better, which is why I was so excited at the possibility that Apple might be working on something similar. Alas...
And I did search and found nothing related to what's going on within iMessage, which I found odd. Nothing wrong with trying to guess what a company is doing.
Thanks for the links ;-)
