如果我写这样的话:
[self.locationManager startUpdatingLocation];
[self.locationManager stopUpdatingLocation];
准确是怎样的坐标?
答案 0 :(得分:0)
您可以在locationManager.startUpdatingLocation()
中执行viewWillAppear
,然后在didUpdateLocations中,当您有位置时,可以检查[horizontalAccuracy][1]
属性
位置的不确定半径,以米为单位。 (只读)
您可以使用此行访问horizontalAccuracy
中的didUpdateLocations
let horizontalAccuracy: CLLocationAccuracy = manager.location!.horizontalAccuracy
如果您对结果满意,可以停止更新,否则继续。
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location:CLLocationCoordinate2D = manager.location!.coordinate
lat = String(location.latitude)
long = String(location.longitude)
let horizontalAccuracy: CLLocationAccuracy = manager.location!.horizontalAccuracy
if (horizontalAccuracy < 5.0){
locationManager.stopUpdatingLocation()
}
}
如果发生错误,您可以再次尝试
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
locationManager.requestLocation()
}
