If you’ve ever participated in group message conversations on your iOS device, you may find that sometimes repeated notifications can begin to get annoying, particularly if there are a lot of people in the group and you’re not actively involved in the conversation. While leaving is always an option, perhaps you still want to be able to check back later as to what’s going on, but don’t need notifications coming up every few seconds as people are chatting away.
The good news is that in iOS 8, you can now enable a “Do Not Disturb” feature or any conversation in Messages. Simply tap on the Details button at the top of the screen, and you’ll see a toggle below the list of people in the conversation allowing you to mute the conversation. This works for one-on-one messaging conversations as well, making it useful for muting things like automated SMS notifications.
