Ios 禁用启用了重大更改的位置

我监视设备的位置有重大变化，一切正常，每次变化我都会在我的Web服务上更新位置

override func viewDidLoad() {
  if CLLocationManager.locationServicesEnabled() {
    switch(CLLocationManager.authorizationStatus()) {
    case .NotDetermined, .Restricted, .Denied:
        print("No access")
    case .AuthorizedAlways, .AuthorizedWhenInUse:
        print("Access")
     }
  } else {
    print("Last know location: \(location)" // retrieve this from the location you saved it. 
    // You could also then set some value on your sever to show that it has been turned off. 
    print("Location services are not enabled")
    }
  }
}

如果用户关闭系统位置，会发生什么情况？是否再次调用重大更改，以便我可以设置用户已禁用位置？

在您的

viewdilaod（）

中执行类似操作，以检查位置服务的状态

override func viewDidLoad() {
  if CLLocationManager.locationServicesEnabled() {
    switch(CLLocationManager.authorizationStatus()) {
    case .NotDetermined, .Restricted, .Denied:
        print("No access")
    case .AuthorizedAlways, .AuthorizedWhenInUse:
        print("Access")
     }
  } else {
    print("Last know location: \(location)" // retrieve this from the location you saved it. 
    // You could also then set some value on your sever to show that it has been turned off. 
    print("Location services are not enabled")
    }
  }
}

然后在

didUpdateLocations

中保存最后一个位置

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
  let location = locations.last // save this in defaults or some way to revive at a later time.
}

：但是AuthorizationChanges事件能否重新启动我的应用程序？如果你的应用程序被强制终止，那么你将无法获得位置更新。如果你的应用程序由于内存压力而被暂停或终止，那么你仍然应该得到对此委托方法的调用。这很容易尝试。我可以说，一旦位置被禁用，您将不会获得任何位置更新：但AuthorizationChanges事件是否可以重新启动我的应用程序？如果您的应用程序被强制终止，那么您无论如何也不会获得位置更新。如果你的应用程序由于内存压力而被暂停或终止，那么你仍然应该得到对此委托方法的调用。这很容易尝试。我可以说，一旦位置被禁用，您将不会得到任何位置更新
