帶有圖像的推送通知-iOS-Swift
[英]Push Notification with Image - iOS - Swift
問題描述
嗨，我只想顯示帶圖像的推送通知。 我用下面的代碼，我不確定我在哪里做錯了我三個多星期，我經歷了很多鏈接，但仍然無法解決。 以下是我的應用程序委托代碼
AppDelegate.Swift

center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
// actions based on whether notifications were authorised or not
guard error == nil else {
//Display Error.. Handle Error.. etc..
return
}
if granted
{
//Do stuff here..
}
else {
//Handle user denying permissions..
}
}
application.registerForRemoteNotifications()
} else {
// Fallback on earlier versions
}

completionHandler();
}
}
extension Data
{
func hexString() -> String
{
return self.reduce("") { string, byte in
string + String(format: "%02X", byte)
}
}
}
以下是我用於自定義推送通知的擴展代碼，
擴展名
import Foundation
extension String {
enum UNNotificationAction : String {
case Accept
case Reject
case Input
}
enum UNNotificationCategory : String {
case Normal
case Cheer
case CheerText
}
enum UNNotificationRequest : String {
case NormalLocalPush
case LocalPushWithTrigger
case LocalPushWithCustomUI1
case LocalPushWithCustomUI2
}
}
extension URL {
enum ResourceType : String {
case Local
case Local1
case Remote
case AttachmentRemote
}
static func resource(type :ResourceType) -> URL
{
switch type {
case .Local:
return Bundle.main.url(forResource: "cheer", withExtension: "png")!
case .Local1:
return Bundle.main.url(forResource: "hahaha", withExtension: "gif")!
case .Remote:
return URL(string: "http://ww1.sinaimg.cn/large/65312d9agw1f59leskkcij20cs0csmym.jpg")!
case .AttachmentRemote:
return URL(string: "https://assets-cdn.github.com/images/modules/open_graph/github-mark.png")!
}
}
}
extension URLSession {
class func downloadImage(atURL url: URL, withCompletionHandler completionHandler: @escaping (Data?, NSError?) -> Void) {
let dataTask = URLSession.shared.dataTask(with: url) { (data: Data?, response: URLResponse?, error: Error?) in
completionHandler(data, error as NSError?)
}
dataTask.resume()
}
}
我的Api回應是
[AnyHashable("aps"):
{
alert = {
body = test;
title = "N-Gal";
};
"mutable-content" = 1;
sound = default;
},
AnyHashable("data"):
{
"attachment-url" = "https://www.n-gal.com/image/cache/catalog/HomeBanner/Banners/1172X450-N-Gal-Footwear-Banner-100x100.jpg";
}]
該代碼基於https://github.com/maquannene/UserNotifications教程。 請給我一個解決此問題的解決方案...預先感謝...！

從您的代碼片段中，我得出結論，您正在談論遠程通知。 這是一個重要的區別。 如果要“豐富”遠程通知（例如添加圖像），則需要UNNotificationServiceExtension ：
對於本地通知，該應用在創建其余通知內容時會添加附件。 要將附件添加到遠程通知中，請使用通知服務擴展在通知內容發送之前對其進行修改 。 有關實現通知服務擴展的更多信息，請參見UNNotificationServiceExtension
資料來源： Apple文檔 。 （強調我的）
該擴展程序位於您的應用程序外部，並在用戶看到遠程通知之前被調用。 這樣，您就有機會在計划發送通知之前加載所有遠程資源。 有關擴展的生命周期以及它們如何與主機應用通信的更多信息，請參閱“ 應用擴展編程指南” 。
要在Xcode中添加擴展名，請轉到File > New > Target然后選擇Notification Service擴展名 ：
這將創建新的擴展目標並將其嵌入主機目標中：
在NotificationService.swift文件中，您將找到可以自定義通知內容的入口點。
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...
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)
}
}
}
請確保查看UNNotificationServiceExtension類概述以獲取更多詳細信息。
