Xcode中添加“CoreLocation.framework”

 #import <CoreLocation/CoreLocation.h>

 @interface ViewController ()<CLLocationManagerDelegate> @property (nonatomic, strong) CLLocationManager* locationManager; @end

//定位管理器    self.locationManager=[[CLLocationManager alloc]init];        if (![CLLocationManager locationServicesEnabled]) {       SSLog(@"定位服务当前可能尚未打开，请设置打开！");        //return;    }        //如果没有授权则请求用户授权    if ([CLLocationManager authorizationStatus]==kCLAuthorizationStatusNotDetermined){        [self.locationManager requestWhenInUseAuthorization];// 当使用app时获取位置//        [self.locationManager requestAlwaysAuthorization];// 一直获取位置    }    //设置代理    self.locationManager.delegate = self;    //设置定位精度    self.locationManager.desiredAccuracy=kCLLocationAccuracyBest;    //定位频率,每隔多少米定位一次    CLLocationDistance distance = 10.0;//十米定位一次    self.locationManager.distanceFilter=distance;    //启动跟踪定位    [self.locationManager startUpdatingLocation];

// 跟踪定位代理方法，每次位置发生变化即会执行（只要定位到相应位置）-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{    CLLocation *location=[locations firstObject];//取出第一个位置    CLLocationCoordinate2D coordinate=location.coordinate;//位置坐标    self.coordinate = coordinate;    SSLog(@"经度：%f,纬度：%f,海拔：%f,航向：%f,行走速度：%f",coordinate.longitude,coordinate.latitude,location.altitude,location.course,location.speed);    //如果不需要实时定位，使用完即使关闭定位服务    [self.locationManager stopUpdatingLocation];}
