iOS CLLocation定位处理

CLLocationManager 需要强引用

var locationManager: CLLocationManager?

定位授权及相关处理

let clAuth = CLLocationManager.authorizationStatus()
            switch clAuth {
            case .notDetermined:
                // 地理位置 选择
                let manager = CLLocationManager()
                locationManager = manager
                manager.delegate = self
                
                // 判断 定位信息的 授权情况
                manager.requestAlwaysAuthorization()
                manager.requestWhenInUseAuthorization()
                manager.startUpdatingLocation()
            case .denied, .restricted:
                // Setting
                if let url = URL(string: UIApplication.openSettingsURLString) {
                     UIApplication.shared.openURL(url)
                }
               
            case .authorizedAlways, .authorizedWhenInUse:
                // 地理位置 选择
                let manager = CLLocationManager()
                locationManager = manager
                manager.delegate = self
                manager.startUpdatingLocation()
            }

CLLocation 代理、数据获取的处理

extension xxxx: CLLocationManagerDelegate {

    //获取定位信息
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
     
        guard let location: CLLocation = locations.last else {
            return
        }
        if location.horizontalAccuracy > 0 {
            
            let lat = Double(String(format: "%.0001f", location.coordinate.latitude)) ?? 0
            let long = Double(String(format: "%.0001f", location.coordinate.longitude)) ?? 0
            
            LonLatToCity(currLocation: location,lat: lat, long: long)
            //停止定位
            locationManager?.stopUpdatingLocation()
        }
      
    }
     
    //出现错误
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print(error)
    }
     
    ///将经纬度转换为城市名
    func LonLatToCity(currLocation: CLLocation, lat: Double, long: Double) {
        let geocoder: CLGeocoder = CLGeocoder()
        geocoder.reverseGeocodeLocation(currLocation) { [weak self](placemark, error) -> Void in
     
            if(error == nil)
            {
                if let placeMark = placemark?.first {
                    
                    if let addressDic: NSDictionary = placeMark.addressDictionary as NSDictionary? {
                        let cityName = addressDic.value(forKey: "City") as? String
                        let countryName = addressDic.value(forKey: "Country") as? String
                        
                        self?.postMomentLocationCell?.cityName = cityName
                        self?.locationStruct = MomentLocationStruct(lat: lat, long: long,cityName: cityName, countryName: countryName)
                    }
                    
                }
                // "CountryCode", "FormattedAddressLines", "Name", "State", "SubLocality"
                
     
            }
            
        }
     
     
    }
   
}
