[英]How to update background location of user within specific time interval using swift 4 iOS?
我正在開發一個應用程序。 我正在更新用戶的背景位置。 並且我想在特定時間間隔內更新該位置。 我搜了很多。 但沒有任何解決方案。 請幫幫我。 下面是我的代碼。 提前致謝。
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
let userLocation :CLLocation = locations[0] as CLLocation
print("user latitude = \(userLocation.coordinate.latitude)")
print("user longitude = \(userLocation.coordinate.longitude)")
self.labelLat.text = "\(userLocation.coordinate.latitude)"
self.labelLongi.text = "\(userLocation.coordinate.longitude)"
DataBaseFunctions.sharedInstance.saveUserDetail(dataToInsert: userLocation)
}
這是在Swift-NOW中,您可以將Timer用於didUpdateLocation與
locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation
locationManager.delegate = self
locationManager.startUpdatingLocation()
var timer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(self.updateLocation), userInfo: nil, repeats: true)
func updateLocation() {
let location: CLLocation = locationManager.location
// Your code
}
//標記:-CLLocationManagerDelegate
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
// Your code
}
