One of the biggest changes in Apple's iOS 5, unveiled Monday, is a welcome overhaul to the iOS's relatively simple notification system. Right now, new alerts pop up in a modal dialog box that interrupts whatever you're doing. If you receive multiple alerts while your device is locked, you have to dismiss each one of them separately, but you can only see one alert per app; if you receive five text messages, you’ll only be alerted to one. If you unlock your phone quickly before you read an alert, and only notice at the end of your swipe, you're out of luck. And sometimes, swiping to unlock your phone just as a notification appeared means that you’ll unintentionally launch the alerting app.
In short, iOS notifications are a notable weakness across the platform—but one that changes completely this fall with the release of iOS 5.
Swipe down from the top of your iOS device to reveal Notifications Center.
iOS 5 introduces Notifications Center. It’s accessible at any time, from any app, with a single swipe straight down from the top of your device. Notifications Center displays your received alerts, organized by app and timestamped. Tap on a specific notification, and you’re taken directly to the right place in the appropriate app. Notifications Center alone solves the problem of dealing with stacked alerts; it’s easy to swipe through a list of all your received notifications.
You can clear out old notifications manually. There’s a small X associated with each app listed in Notifications Center. When you tap it, it turns into the word Clear; tap that, and you remove all of the app’s old notifications. Old notifications aren’t removed automatically—though that seems like the sort of sentiment that might need a “yet” attached. Don’t be surprised if by iOS 5’s official fall release (or a subsequent update shortly thereafter), developers can leverage an API to indicate when you’ve clearly processed the data from a notification (e.g., viewed your friend’s play in Words With Friends), thus removing the notification automatically.
Over in the Settings app, you can choose how your notifications are organized. If you sort by Time, the apps with the most recent alerts appear at the top of Notifications Center. If you choose Manual sort instead, you determine (still in the Settings app) the order in which apps will appear.
When new notifications arrive, you’ll see a temporary, floating banner at the top of the screen—it looks a lot like Game Center notifications you may have encountered. Of course, those floating banners are a bit easier to miss if you’ve glanced away from the screen or are deeply engrossed in your app. Again, though, since each new alert gets saved in your Notifications Center, it’s painless to check and ensure you’re caught up.
