Rich Notifications
From MBurger you can send medias (images/videos/audio) with a push notification. The link of the media will be sent in the payload of the notifications in the
media_url field. To view the media sent in the notifications follow tihs steps, as described in the MPush documentation. . This will create a class that will intercept all push notification sent to the app, you will be able to change its content from this class.
In the notification service class use this code to download the media and attach to the push notification.
class NotificationService: UNNotificationServiceExtension {
var contentHandler: ((UNNotificationContent) -> Void)?
var bestAttemptContent: UNMutableNotificationContent?
override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
self.contentHandler = contentHandler
bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)
if let bestAttemptContent = bestAttemptContent {
if let mediaUrl = request.content.userInfo["media_url"] as? String, let fileUrl = URL(string: mediaUrl) {
let type = request.content.userInfo["media_type"] as? String
downloadMedia(fileUrl: fileUrl, type: type, request: request, bestAttemptContent: bestAttemptContent) {
contentHandler(bestAttemptContent)
}
} else {
contentHandler(bestAttemptContent)
}
}
}
func downloadMedia(fileUrl: URL, type: String?, request: UNNotificationRequest, bestAttemptContent: UNMutableNotificationContent, completion: @escaping () -> Void) {
let task = URLSession.shared.downloadTask(with: fileUrl) { (location, _, _) in
if let location = location {
let tmpDirectory = NSTemporaryDirectory()
let tmpFile = "file://".appending(tmpDirectory).appending(fileUrl.lastPathComponent)
let tmpUrl = URL(string: tmpFile)!
do {
try FileManager.default.moveItem(at: location, to: tmpUrl)
var options: [String: String]? = nil
if let type = type {
options = [String: String]()
options?[UNNotificationAttachmentOptionsTypeHintKey] = type
}
if let attachment = try? UNNotificationAttachment(identifier: "media." + fileUrl.pathExtension, url: tmpUrl, options: options) {
bestAttemptContent.attachments = [attachment]
}
completion()
} catch {
completion()
}
}
}
task.resume()
}
override func serviceExtensionTimeWillExpire() {
if let contentHandler = contentHandler, let bestAttemptContent = bestAttemptContent {
contentHandler(bestAttemptContent)
}
}
}
