There are
several changes need to be done when updating your iOS 7 app to iOS 8. If your
app uses notification have come to write place J.
Previously
iOS 7 has User Notifications and Silent Notifications. User notifications are
the things that the user can interact with see or hear under device. They are
coming directly form the app or from APNS server. In iOS 7 when we get a notification
we could do the following.
1. Badge the app icon
2. Play a sound
3. Alerts tip down from the top of the screens.
Silent notifications are the push
payloads you get from APNS server with the content-available set to 1, to do
back ground task with out not disturbing the user. For example download the new
content from the server, which will enable up to date update information when
the user uses app in the next time.
Let’s see
the changes in iOS 8 Notifications. There are basically 4 updates in iOS 8.
They are
1. User notifications - Changes in
registration.
2. Notification actions.
3. Remote notification Changes in
registration.
4. Local notifications.
In this
post I’m going to talk about what are changes in User notifications and Remote
Notifications.
First we
look at the User Notification
In iOS 8 regardless of your
application going to show remote notifications or local notifications the app
must first register to user those notification.
1.
Create
Notification Type object.
2.
Create
notification settings object with the created notification types.
3.
Call
the application did register notification with settings method.
This will ask from the user by displaying an alert
message that the app is going to user notification is it ok with you.
4. Once
the user have replied to the message, the app delegate will get a call back (didRegisterUserNotificationSettings).
From that call back you will get up to date
most current notification settings object with user preferred notification
types.
Remote
Notifications.
If you
are using remote notification in your app first you need to register for the
notification as I discussed above. Then at the didRegisterUserNotificationSettings call back method you need to call [application registerForRemoteNotifications]. That’s it. You are done J.
Then the
application delegate will get the call back to didRegisterForRemoteNotificationsWithDeviceToken
or
didFailToRegisterForRemoteNotificationsWithError. From that point no change its same
as the previous versions.
In the
next post; Notification changes in iOS 8 – Part 1, I will discuss the one of the
most excited and interesting feature in iOS 8 Notification which is Location
base notifications. J
