Deep linking to Facebook Messenger
问题 From a lot of searching, I found that using fb-messenger://user-thread/ID can be used to deep link to Messenger and open the existing thread with the passed in FB ID or start a new thread if not existent. It pops over to Messenger and opens a thread, but the thread is with Facebook User and doesn't actually send. See image below. Clicking Facebook User in the header goes to a detail view with the correct user's image and name. How do I make this work correctly? 回答1: As WizKid (FB Employee)
