+1 for this I just logged in to post about this as well. I just finished building an app and the user needs to be able to share their video. I got excited when using the UIActivityViewController because if you attach the video’s local URL it’ll place a thumbnail in the TWTRComposer, but when you actually share it it just shares the URL text.
I had to create my own custom Twitter share modal so the user could upload their video via the REST API, but I’ve lost out on some of the great composer features like auto-completing/suggesting twitter handles.
Maybe we could reach a middle ground where I could still upload the user’s video via the REST API, and attach the returned media ID to the TWTRComposer?
Anyways glad to see you guys are active and listening in these forums. We really appreciate it.
Cheers.
