CLLocation在IOS中停止

Question

I'm trying to send my position with iOS and swift, but after a while the application is stopped and stops working.

    class Location:NSObject, CLLocationManagerDelegate {

private var locationManager = CLLocationManager()
private var errorLocation: Bool = false
private var stuffLocation: CLLocation!

var outSocket: OutSocket!
var timer: NSTimer!
var stuff: Stuff!

override init() {
    super.init()
    outSocket = OutSocket()
    setupLocation()
}

func setupLocation() {
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestWhenInUseAuthorization()
    locationManager.activityType = CLActivityType.Fitness
    locationManager.allowsBackgroundLocationUpdates = true
    locationManager.startUpdatingLocation()
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if !errorLocation {
        errorLocation = true
        locationManager.allowDeferredLocationUpdatesUntilTraveled(10, timeout: 50)
        stuffLocation = locations[0]
        if timer == nil {
            timer = NSTimer.scheduledTimerWithTimeInterval(5, target: self, selector: #selector(Location.sendDataToServer), userInfo: nil, repeats: true)
        }
    }
}
}
func locationManager(manager: CLLocationManager, didFinishDeferredUpdatesWithError error: NSError?) {
    errorLocation = false
}

This is my code, if anyone has done something similar or know how to prevent the APP stops will appreciate it.

If you want your app to keep getting GPS location updates while it is in the background you have to add an entry to the UIBackgroundModes array in the app's info.plist, and then you need to ask the user for permission. Do a search in the Xcode docs on UIBackgroundModes . Specifically look at the location value.

You will also need to make a case to Apple that you app should be allowed to use the GPS from the background when you submit the app to the app store.

Note that you are going to drain the user's battery in a hurry if you keep the GPS on at all time, AND a TCP socket in order to upload the coordinates.
