似乎我的应用在终止状态下没有启动并调用位置更新。由于在办公室内来回移动以触发重要的位置更改不是一件容易的事情，所以很难测试不起作用的内容。是否有一种方法可以在模拟器中模拟位置更改，同时关闭应用程序？我已经尝试使用“模拟器>调试>位置>[城市自行车骑行，... ]”，但似乎仅在应用程序运行时才有效。我甚至尝试创建一个方案，在编译后不会自动启动应用程序。您有任何建议如何调试此类问题吗？（到目前为止，我只是在每次应用程序启动时记录在单独的文件中，即使不幸的是，当应用程序处于关闭状态时，应用程序也不会在后台启动）这是我的应用程序委托中的代码：

lazy var locationManagerFitness: CLLocationManager! = {
let manager = CLLocationManager()
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.distanceFilter = 1.0
manager.activityType = CLActivityType.Fitness
manager.delegate = self
manager.requestAlwaysAuthorization()
return manager
