在锁定屏幕的左下角添加应用程序图标

Question

我已在设备上安装了应用程序，当它进入特定区域时，我想在锁定屏幕的左下角显示它，但我不想使用iBeacon，有没有办法使用存折卡来添加位置和日期/时间到pass.json文件，并从存折卡中读取该位置和时间，并在iPhone的锁定屏幕上的左下角显示该应用程序，具体取决于存折卡中的位置或时间？

The launch icon you see on the lock screen is put there CoreLocation launches an app into the background based on iBeacon or Geofence detection. While you said you don't want to use iBeacons with your app, you can still accomplish the same thing with CoreLocation Geofences. The way it would work is that you would register the geofences with your app, and then when you cross the geofence with your app in the background, the icon will appear on the lock screen. Tapping on the icon launches your app.

You can find a tutorial on setting up Geofences with your app here: http://www.raywenderlich.com/95014/geofencing-ios-swift
