If you’re looking for a way to keep Facebook dating on your iPhone, there are a few options. You can use the Facebook app to sign in and set up notifications for when new messages come in, or you can use the Facebook app’s “Dating” feature. If you’re using the “Dating” feature, you can set up rules about who can message you and how long it will take for a response. You can also choose to have messages sent only to people who have liked your profile or people who have commented on your posts.
