高德地图的定位

 按照说明稳定获取apiKey  引用11个库文件，

#import "ViewController.h"

#import <MAMapKit/MAMapKit.h>

@interface ViewController ()<MAMapViewDelegate>

{

    MAMapView *_mapView;

    CLLocation *_userLocation;

}

@end

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    //  2c37b41189e673357bf55d23edeeed7c

    [MAMapServices sharedServices].apiKey = @"2c37b41189e673357bf55d23edeeed7c";

    _mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 0, maiScr.width, maiScr.height)];

    _mapView.delegate = self;

      [self.view addSubview:_mapView];

 

/**********************     上边是地图的显示    *************************************/

    //打开定位

    _mapView.showsUserLocation=YES;

    _mapView.userTrackingMode=MAUserTrackingModeFollowWithHeading;

    [_mapView setZoomLevel:16.1 animated:YES];   

}

//当位置更新时，会进定位回调，通过回调函数，能获取到定位点的经纬度坐标，示例代码如下

//这个函数可以用于地图回归当前坐标原点

-(void)mapView:(MAMapView *)mapView didUpdateUserLocation:(MAUserLocation *)userLocation updatingLocation:(BOOL)updatingLocation

{

    if (updatingLocation) {

        //打印当前经纬度

       // NSLog(@"latitude  :  %f  ,longitude   :   %f",userLocation.coordinate.latitude,userLocation.coordinate.longitude);

 

　　　　　　　　/******************    CLLocation类创建的userLocation赋值给当前view中心点即可    *********************/

        _userLocation=userLocation.location;

        _mapView.centerCoordinate=_userLocation.coordinate;

    }
