在Swift中使用CLLocationManager的正确代码设计

import CoreLocation

let locationManager = CLLocationManager()

locationManager.delegate = self

locationManager.requestWhenInUseAuthorization()

locationManager.requestAlwaysAuthorization()

locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.distanceFilter = kCLDistanceFilterNone

locationManager.startUpdatingLocation()

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    // 处理位置更新
    if let location = locations.last {
        // 获取最新的位置信息
        print("经度: \(location.coordinate.longitude)")
        print("纬度: \(location.coordinate.latitude)")
    }
}

locationManager.stopUpdatingLocation()
