我試圖在ios 10中實現豐富的遠程通知。我實現了這個代碼。收到通知後的控件會在這裏,但我不知道如何下載圖像並顯示在通知中。提前致謝。對於豐富的遠程通知使用UNNotificationServiceExtension
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 {
// Modify the notification content here...
//print("title for image = \(bestAttemptContent.title)")
bestAttemptContent.title = "\(bestAttemptContent.title) [modified]"
contentHandler(bestAttemptContent)
}
}
override func serviceExtensionTimeWillExpire() {
// Called just before the extension will be terminated by the system.
// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
if let contentHandler = contentHandler, let bestAttemptContent = bestAttemptContent {
contentHandler(bestAttemptContent)
}
}
}
感謝您的回覆@Rajat。我試過這個,但它仍然沒有下載圖像。仍然只顯示文本數據。我不知道我在做什麼錯 – Prajyot
檢查文件是否正在下載,也檢查你是否從通知數據中獲得有效的URL – Rajat
是的,網址是有效的。但是他們要在什麼地方儲存?我看過照片,沒有。 – Prajyot
