当用户单击其Mac上的通知警报消息时,我正在尝试获取警报消息详细信息。
打开应用时,我没有问题获取警报。以下代表对应用程序已经打开时正常工作。
func application(_ application: NSApplication,
didReceiveRemoteNotification userInfo: [String : Any])
但是,当通过单击OD打开应用程序时,警报通知我必须从
中获取UserInfofunc applicationDidFinishLaunching(_ aNotification: Notification)
我无法在此功能中检索警报userInfo
。
let mydictionary = aNotification.userInfo
let mydesc = mydictionary!.description
os_log("aNotification.userInfon= %{public}@", log: osLog, mydesc)
os_log
的输出,我可以在描述中看到警报消息。
aNotification.userInfon= [AnyHashable("NSApplicationLaunchIsDefaultLaunchKey"): 0, AnyHashable("NSApplicationLaunchUserNotificationKey"): <UNNotificationResponse: 0x600003ac1480; actionIdentifier: com.apple.UNNotificationDefaultActionIdentifier, notification: <UNNotification: 0x600003ac1580; date: 2019-05-08 18:26:59 +0000, request: <UNNotificationRequest: 0x6000034cd560; identifier: E6D76BF3-6643-4627-BF38-3B11B5C3F0B3, content: <UNNotificationContent: 0x600000fe0780; title: (null), subtitle: (null), body: (14) - iPhone - Tom Owen, summaryArgument: , summaryArgumentCount: 0, categoryIdentifier: , launchImageName: , threadIdentifier: , attachments: ( ), badge: 0, sound: <UNNotificationSound: 0x600001ee92c0>,, trigger: <UNPushNotificationTrigger: 0x6000038fa780; contentAvailable: NO, mutableContent: NO>>>>]
我尝试了多种访问"字典"的方法,以下是一种方法。
if let aps = aNotification.userInfo!["aps"] as? NSDictionary {
os_log(" aNotification.userInfo ok", log: osLog)
if let alert = aps["alert"] as? NSDictionary {
os_log("alert ok", log: osLog)
if let alertMessage = alert["body"] as? String {
os_log("body ok", log: osLog)
message = alertMessage
}
}
} else {
os_log("no aNotification.userInfo!", log: osLog)
}
但是,我不断获得" no anotification.userinfo!"
我应该如何从userInfo
?
请仔细查看日志。您必须使用密钥launchUserNotificationUserInfoKey
获取用户通知。该密钥的值是UNNotificationResponse
实例。
您获得
的body
func applicationDidFinishLaunching(_ notification: Notification)
if let response = notification.userInfo?[NSApplication.launchUserNotificationUserInfoKey] as? UNNotificationResponse {
let content = response.notification.request.content
let body = content.body
message = body
}
}
但是didReceiveRemoteNotification
通过传统userInfo
字典
func application(_ application: NSApplication, didReceiveRemoteNotification userInfo: [String : Any]) {
if let aps = userInfo?["aps"] as? [String:Any] { // please use Swift native types
os_log(" aNotification.userInfo ok", log: osLog)
if let alert = aps["alert"] as? [String:Any] {
os_log("alert ok", log: osLog)
if let alertMessage = alert["body"] as? String {
os_log("body ok", log: osLog)
message = alertMessage
}
}
} else {
os_log("no aNotification.userInfo!", log: osLog)
}
}
