Change Push content from Userinfo to ios
When a notification is received, I want to change the user's information content before being shown in a mobile notification on iOS.
"aps": {
"alert": {
"body": "hello",
"sound": "Default"
"badge": "1"
}
}
Example. I want to show the world instead of a greeting.
Is this possible in iOS 10?

You can implement an extension for it. Here is the link: Extending Notifications
You have to implement didReceive (_: withContentHandler :) method and use it to handle incoming notifications.
override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
self.contentHandler = contentHandler
bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
if let bestAttemptContent = bestAttemptContent {
// Modify the notification content here
// Convert received string
let data = bestAttemptContent.body.data(using: .utf8)!
// Apply encoded string
bestAttemptContent.body = String(data: data, encoding: .utf16)
contentHandler(bestAttemptContent)
}
}
