iOS9 中的 CLLocationManager 允许后台位置更新

使用 CLLocationManager 实现 iOS9 中的后台位置更新

swift
import CoreLocation
class LocationManager: NSObject, CLLocationManagerDelegate {
    let locationManager = CLLocationManager()
    
    override init() {
        super.init()
        
        locationManager.delegate = self
        locationManager.allowsBackgroundLocationUpdates = true
        locationManager.requestAlwaysAuthorization()
    }
    
    func startUpdatingLocation() {
        locationManager.startUpdatingLocation()
    }
    
    func stopUpdatingLocation() {
        locationManager.stopUpdatingLocation()
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        guard let location = locations.last else { return }
        
        // 处理位置更新
        print("经度：\(location.coordinate.longitude), 纬度：\(location.coordinate.latitude)")
    }
    
    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedAlways {
            // 授权成功，可以开始后台位置更新
            startUpdatingLocation()
        }
    }
}
