iOS8 and iOS7 Push Notification Payload

问题:

Since iOS8 came up with interactive notification, is there any significant changes to make Payload to send push notification? If changes are there then how it will be handled in lower versions of iOS?

回答1:

There is a small difference in payloads as given. However same interactive notification payload can be pushed to iOS7 or less, it will be shown as normal notification.

iOS8 Interactive Push Payload

{"aps":{"alert":"Hello Testing","badge":1,"sound":"default","category":"your_category_key"}}

"your_category_key" is nothing but the UIMutableUserNotificationCategory identifier.

Older Version less than iOS8 Payload

{"aps":{"alert":"Hello Testing","badge":1,"sound":"default"}}

And Apple has extended the payload size up to 2048 Bytes (2K). Previously it was 256 Bytes only.
