ios – Detect如果在未启动应用程序且用户未通过它们打开应用程序时收到推送通知

是否可以检测应用程序脱机时是否收到推送通知(不是在后台或前台?如果用户直接从弹簧板而不是推送通知警报打开应用程序的情况).
最佳答案
在你的AppDelegate做这个(抱歉快速实现):

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // We see if we have a recent push notification date stored in the user defaults.
    // If there hasn't been a recent one sent this if block will not be entered.
    if let mostRecentPushNotificationDate = NSUserDefaults.standardUserDefaults().objectForKey("mostRecentPushNotification") as? NSDate {

        // We find the difference between when the notification was sent and when the app was opened
        let interval = NSDate().timeIntervalSinceDate(mostRecentPushNotificationDate)

        // Check to see if we opened from the push notification
        if let notification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? [String: AnyObject] {
            print("we opened from the push notifcation and the time difference was \(interval) seconds.")
        }

        // We did not open from a push notification
        else {
            print("we opened from the spring board and the time difference was \(interval) seconds.")
        }

        // We remove the object from the store so if they open the app without a notification being sent we don't check this if block
        NSUserDefaults.standardUserDefaults().removeObjectForKey("mostRecentPushNotification")
    }


    return true
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

    // Set a flag when a push notification was sent
    NSUserDefaults.standardUserDefaults().setObject(NSDate(), forKey: "mostRecentPushNotification")
}
