我正在尝试为我的应用程序进行地理围栏。当我的应用程序运行时，我模拟位置。它收到了地理围栏，但当它在后台时，它没有收到任何地理围栏。(我已经遵循了本教程的地理围栏核心位置的地理围栏
但我使用谷歌地图显示地图的要求)
有我的AppDelegate 的代码
import GoogleMaps
import GooglePlaces
import UserNotifications

我无法识别问题。我注意到，如果我运行带有核心位置的地理围栏的Finished示例代码，并在iPhone上单击主页按钮，那么AppDelegate的函数应用程序WillTerminate(_application:UIApplication)不会调用，但当我运行应用程序时，它会调用。我做错了什么？如何解决此问题
您是否已在项目设置的"功能"选项卡上启用"背景模式"并选中"位置更新"复选框？如果不这样做，那么你可以在后台模式下获得更新位置。
我已经解决了这个问题，问题是info.list have uiapplicationexitsonsupest=yes。我删除了它，现在它运行良好
