ios - 应用程序关闭时如何处理 UNNotificationAction？

Question

当应用程序关闭(不在后台)时如何处理新的 iOS10 通知操作？

当应用程序被最小化时，一切正常:

UNUserNotificationCenter.current().delegate = x

并处理它

class x: UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Swift.Void) {
    }
}

但是当应用程序关闭并且用户在通知中点击操作时什么都不会调用......也许我无法处理后台任务并且我总是必须启动应用程序？

通知操作按钮处理可以在 Extension 中完成以及在 Containing App .

当点击操作按钮时， handle 首先转到 Extension然后到 Containing App如果需要的话。如 Extension不处理通知 Action ，句柄传递给 containing app.

Tapping a button launches your app (either in the foreground or background) and gives you a chance to perform the indicated action.

分机处理:

func didReceive(_ response: UNNotificationResponse, completionHandler completion: @escaping (UNNotificationContentExtensionResponseOption) -> Void)
{
     //You need to handle all the actions that appear with notification..
     completion(.dismissAndForwardAction)
}

完成闭包采用 UNNotificationContentExtensionResponseOption 类型的值:

enum UNNotificationContentExtensionResponseOption : UInt
{
    case doNotDismiss //the custom UI is not dismissed after handling the action
    case dismiss //the custom UI is dismissed after handling the action
    case dismissAndForwardAction //the custom UI is dismissed after handling the action and the control is then passed to containing app for any additional handling
}

在包含应用程序中处理:

extension AppDelegate : UNUserNotificationCenterDelegate
{
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
    {
        // Action handling - handling for all actions is not required
        completionHandler()
    }
}
