Question

即使在应用程序被终止/终止/暂停时，我也试图在所有状态下获取位置更新。我在xcode中启用了后台提取并实现了以下代码（使用了引用“Capture location in all states app”）。但是，当我终止应用程序时，它会在AppDelegate类上给出一条红线。我不明白这里有什么问题。我在这里使用问题“Getting location for an iOS app when it is in the background and even killed”的解决方案做了这个，但它不适用于ios 9.请帮助我或告诉我另一个解决方案。

更新的代码 -

class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {

var window: UIWindow?
var locationManager: CLLocationManager?
var significatLocationManager : CLLocationManager?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
    if(UIApplication.sharedApplication().backgroundRefreshStatus == UIBackgroundRefreshStatus.Available){
        print("yessssss")
    }else{
        print("noooooo")
    }

    if let launchOpt = launchOptions{
        if (launchOpt[UIApplicationLaunchOptionsLocationKey] != nil) {
            self.significatLocationManager = CLLocationManager()
            self.significatLocationManager?.delegate = self
            self.significatLocationManager?.requestAlwaysAuthorization()
            if #available(iOS 9.0, *) {
                self.significatLocationManager!.allowsBackgroundLocationUpdates = true
            }
            self.significatLocationManager?.startMonitoringSignificantLocationChanges()

        }else{

            self.locationManager           = CLLocationManager()
            self.locationManager?.delegate = self
            self.locationManager?.requestAlwaysAuthorization()
            if #available(iOS 9.0, *) {
                self.locationManager!.allowsBackgroundLocationUpdates = true
            }

            self.locationManager?.startMonitoringSignificantLocationChanges()
        }

    }else{

        self.locationManager           = CLLocationManager()
        self.locationManager?.delegate = self
        self.locationManager?.requestAlwaysAuthorization()
        if #available(iOS 9.0, *) {
            self.locationManager!.allowsBackgroundLocationUpdates = true
        }

        self.locationManager?.startMonitoringSignificantLocationChanges()

    }

    return true
}



func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]){

    let locationArray = locations as NSArray
    let locationObj = locationArray.lastObject as! CLLocation
    let coord = locationObj.coordinate
        }


func applicationDidEnterBackground(application: UIApplication) {

    if self.significatLocationManager != nil {

        self.significatLocationManager?.startMonitoringSignificantLocationChanges()
    }else{

        self.locationManager?.startMonitoringSignificantLocationChanges()
    }


}

希望你能得到答案。它为我工作。现在我正在尝试在＆＃39; didUpdateLocations＆＃39;函数被调用，以便我可以在应用程序未运行时将用户当前位置存储在服务器中（暂停/终止/终止）。

我不认为苹果允许在应用暂停/终止时发出任何http请求。但是如果服务器收到了位置更新的请求，那么我很高兴去那。因为我不需要从服务器回复。需要大量的测试....

即使应用程序被终止或终止，位置也会更新
