获取用户经纬度（swift和OC）

不知道是老了还是怎么样，脑子里装的东西越来越多了，写过的东西也会忘记。实践强调我，好记性不如烂笔头，做的东西再多，都要多写多记，希望我的内容能对你有帮助

无论swift和oc，其实原理都是一样的
详细步骤如下
1、导入库CoreLocation
2、实例化对象 var locationManager:CLLocationManager = CLLocationManager()
3、继承协议CLLocationManagerDelegate
4、对象属性设置
5、实现协议方法，获取地理信息
4和5如下代码所示

swift
此处注意
locationManager.requestWhenInUseAuthorization()
这句代码是在用户使用app的时候弹出请求框

    func reLocationAction(){
        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        locationManager.desiredAccuracy = kCLLocationAccuracyBest//定位最佳
        locationManager.distanceFilter = 500.0//更新距离
        locationManager.requestWhenInUseAuthorization()
        if (CLLocationManager.locationServicesEnabled()){
            locationManager.startUpdatingLocation()
            print("定位开始")
        }
    }
    func locationManager(_ manager: CLLocationManager, didFinishDeferredUpdatesWithError error: Error?) {
        LSDKLog("获取经纬度发生错误")
        LSDKLog(error)
    }
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]){
        let thelocations:NSArray = locations as NSArray
        let location = thelocations.lastObject as! CLLocation
        let latitude = location.coordinate.latitude
        let longitude = location.coordinate.longitude
        latitudeStr = Float(latitude)
        longitudeStr = Float(longitude)
        LSDKLog("经纬度")
        LSDKLog(latitudeStr)
        LSDKLog(longitudeStr)
        locationManager.stopUpdatingLocation()
    }

OC代码

-(void)getLocation
{
    //判断定位功能是否打开
    if ([CLLocationManager locationServicesEnabled]) {
        locationmanager = [[CLLocationManager alloc]init];
        locationmanager.delegate = self;
        [locationmanager requestAlwaysAuthorization];
        [locationmanager requestWhenInUseAuthorization];
        //设置寻址精度
        locationmanager.desiredAccuracy = kCLLocationAccuracyBest;
        locationmanager.distanceFilter = 50.0;
        [locationmanager startUpdatingLocation];
    }
}
#pragma mark CoreLocation delegate (定位失败)
//定位失败后调用此代理方法
-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    //设置提示提醒用户打开定位服务
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"允许定位提示" message:@"请在设置中打开定位" preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"打开定位" style:UIAlertActionStyleDefault handler:nil];
    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
    [alert addAction:okAction];
    [alert addAction:cancelAction];
    [self presentViewController:alert animated:YES completion:nil];
}
#pragma mark 定位成功后则执行此代理方法
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations
{
    [locationmanager stopUpdatingHeading];
    CLLocation *currentLocation = [locations lastObject];
    CLGeocoder *geoCoder = [[CLGeocoder alloc]init];
    //打印当前的经度与纬度
    //    YEAFNAppLog(@"%f,%f",currentLocation.coordinate.latitude,currentLocation.coordinate.longitude);
    //反地理编码
    [geoCoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
        if (placemarks.count > 0) {
            CLPlacemark *placeMark = placemarks[0];
            self.currentCity = placeMark.locality;
            if (!self.currentCity) {
                self.currentCity = @"无法定位当前城市";
            }
            /*看需求定义一个全局变量来接收赋值*/
            YEAFNAppLog(@"当前国家----%@",placeMark.country);//当前国家
            YEAFNAppLog(@"当前的城市%@",self.currentCity);//当前的城市
            YEAFNAppLog(@"%@",placeMark.subLocality);//当前的位置
            YEAFNAppLog(@"%@",placeMark.thoroughfare);//当前街道
            YEAFNAppLog(@"%@",placeMark.name);//具体地址
            
        }
    }];
}
