我在OSX上的开发应用程序中有菜鸟。我想使用Share extension创建应用。加载内容后,我想显示Notification,但出现错误“此应用程序不允许进行通知”。我不明白为什么requestAuthorization方法不显示具有权限的对话框窗口,以及我如何允许应用程序发送通知。

这是我的代码:

import Cocoa
import UserNotifications

class ShareViewController: NSViewController {
    override func loadView() {
        self.view = NSView()

        // Insert code here to customize the view
        let item = self.extensionContext!.inputItems[0] as! NSExtensionItem
        NSLog("Attachment = %@", item.attachments! as NSArray)
        showNotification()
        let outputItem = NSExtensionItem()
        let outputItems = [outputItem]
        self.extensionContext!.completeRequest(returningItems: outputItems, completionHandler: nil)
    }

    func showNotification() -> Void {
        let notificationCenter = UNUserNotificationCenter.current()
        notificationCenter.requestAuthorization(options: [.alert, .badge]) {
            (granted, error) in
            if granted {
                print("Yay!")
            } else {
                print("D'oh") // Print this, not authorized
            }
        }
        let content = UNMutableNotificationContent()

        content.title = "Hello"
        content.body = "This is example"
        content.sound = UNNotificationSound.default
        content.badge = 1
        let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
        let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
        notificationCenter.add(request) { (error : Error?) in
            if let theError = error {
                print(theError) // Print Domain=UNErrorDomain Code=1 "Notifications are not allowed for this application"
            }
        }
    }
}

我在文档中什么都看不到,说您无法通过扩展程序安排新的本地通知。但是,我在see an apple support ticket的地方也要像我一样处理这个问题。

基本上,此故障是竞争条件。关键是调用此扩展方法的contentHandler:

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

直到

的完成处理程序
notificationCenter.add(request: UNNotificationRequest>, withCompletionHandler: ((Error?) -> Void)

被调用。它为我工作。有道理吗?

Apple不允许通过共享扩展程序发送通知。
