iOS Rich通知无法正常工作

Question

我需要在当前应用程序中使用图像实现丰富的通知。

我已经实现了一切，并且工作正常。并接收推送通知，但只获取标题和消息，但不获取图像作为附件

没有可变内容的正常通知正常工作。

据我测试，证书方面没有问题..我使用NotificationService扩展来显示媒体附件

有什么想法吗？

我的有效负载如下所示：

[AnyHashable("title"): New trailer released- Hindi Movies, AnyHashable("message"): Kuchh Bheege Alfaaz - Official Hindi Trailer, AnyHashable("aps"): {
    alert = "New trailer released- Hindi Movies";
    badge = 2;
    sound = default;
}, AnyHashable("trailer_img"): uploads/trailer_image/9703831856a7968b8b5cf6b10357dc2c1.jpg]

我的NotificationService类代码如下：

class NotificationService: UNNotificationServiceExtension {

    var contentHandler : ((UNNotificationContent) -> Void)?
    var content        : UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest,
                             withContentHandler contentHandler:
        @escaping (UNNotificationContent) -> Void) {

        self.contentHandler = contentHandler
        self.content        = (request.content.mutableCopy()
            as? UNMutableNotificationContent)

        let userInfo : [AnyHashable: Any] = request.content.userInfo
        print(userInfo)

        if let bca = self.content {

            func save(_ identifier: String,
                      data: Data, options: [AnyHashable: Any]?)
                -> UNNotificationAttachment? {

                    let directory = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(ProcessInfo.processInfo.globallyUniqueString,
                                                                                                        isDirectory: true)

                    do {
                        try FileManager.default.createDirectory(at: directory,
                                                                withIntermediateDirectories: true,
                                                                attributes: nil)
                        let fileURL = directory.appendingPathComponent(identifier)
                        try data.write(to: fileURL, options: [])
                        return try UNNotificationAttachment.init(identifier: identifier,
                                                                 url: fileURL,
                                                                 options: options)

                    } catch {
                    }

                    return nil
