Question

以下是unoproj设置的一部分。我还应该进行哪些设置？保险丝设置错误吗？还是快速的文件调用有问题？

[.unoproj file]
"SystemCapabilities": {
  "Push": true
}
"Includes": [
"*",
"iOS/NotificationService.swift:Swift:iOS",
"iOS/NotificationViewController.swift:Swift:iOS"
],

要调用DidRecive函数需要进行哪些设置？

import UserNotifications

class NotificationService: UNNotificationServiceExtension {

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

    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        print("--------------------------------------------------This is a log message.")

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

        if let bestAttemptContent = bestAttemptContent {
            // Modify the notification content here...
            bestAttemptContent.title = "\(bestAttemptContent.title) [modified]"

            var urlString:String? = nil
            if let urlImageString = request.content.userInfo["image-url"] as? String {
                urlString = urlImageString
            }

            if urlString != nil, let fileUrl = URL(string: urlString!) {
                print("fileUrl: \(fileUrl)")

                guard let imageData = NSData(contentsOf: fileUrl) else {
                    contentHandler(bestAttemptContent)
                    return
                }

                guard let attachment = UNNotificationAttachment.saveImageToDisk(fileIdentifier: "image.jpg", data: imageData, options: nil) else {
                    print("error in UNNotificationAttachment.saveImageToDisk()")
                    contentHandler(bestAttemptContent)
                    return
                }

                bestAttemptContent.attachments = [ attachment ]
            }

            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)
        }
    }

}

@available(iOSApplicationExtension 10.0, *)
extension UNNotificationAttachment {

    static func saveImageToDisk(fileIdentifier: String, data: NSData, options: [NSObject : AnyObject]?) -> UNNotificationAttachment? {
        let fileManager = FileManager.default
        let folderName = ProcessInfo.processInfo.globallyUniqueString
        let folderURL = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(folderName, isDirectory: true)

        do {
            try fileManager.createDirectory(at: folderURL!, withIntermediateDirectories: true, attributes: nil)
            let fileURL = folderURL?.appendingPathComponent(fileIdentifier)
            try data.write(to: fileURL!, options: [])
            let attachment = try UNNotificationAttachment(identifier: fileIdentifier, url: fileURL!, options: options)
            return attachment
        } catch let error {
            print("error \(error)")
        }

        return nil
    }
}

我不确定代码是否适用。

我不知道如何将快速文件应用于保险丝项目。

谢谢...
