Notification banners and alerts aren't new to iOS, but the ability to expand and interact with them is. Apple's new iOS 8 has ushered in some small, yet convenient features to the banner and alert notifications that make them truly interactive. The new additions, as you will see, makes it easy to complete simple tasks without leaving the current screen you're in.
In order for this new feature to work, you will need banner or alert notifications enabled, which need to be enabled for each app individually in the Notifications section of your Settings menu.
There is no need to exit the screen you're in just to send your friend a quick response through text. Pull down the notification and send a reply, or even an audio message. Once sent, you can continue your activity.
Emails can now be casually trashed or marked as read without entering the Mail application. Simply pull down the banner and select the action.
I use the Reminders application a lot (especially for location-based alerts), so the ability to snooze a reminder or mark it as complete is extremely convenient.
As mentioned, these notifications are also interactive alerts. As soon as the notification comes through, dismiss or take action, then continue doing your thing.
Again, alert styles can be changed in your Settings app under the Notifications preferences.
Unfortunately, I was unable to get the Calendar app banner notifications to work on two different iOS 8 devices, so this might be a bug that needs to be reported. But, you are supposed to get a notification like the one below whenever you're added to a meeting or event.
As soon as third-party apps begin updating to include new iOS 8 features, you will be able to perform similar functions from banners, like commenting or liking a Facebook post.
