1，我们先申请一个appkey，申请appkey必须注册高德开发者

2，高德SDK的下载，现在SDK分别有三个库，根据你的app 里面的集成需求，可以选择性的下载添加到自己的工程里，他们分别是 2D地图库，3D地图库，还有搜索库；

3，添加SDK进自己的项目（工程）里，添加的时候注意路径问题，添加完高德SDK之后，我们还需要添加一些系统自带库，有了这些才能支持高德SDK的运行，他们分别如下图

4，运行环境的配置，在TARGETS->Build Settings->Other Linker Flaggs 中添加－ObjC。

5，实现地图

- (void)viewWillAppear:(BOOL)animated{    [super viewWillAppear:YES];        [MAMapServices sharedServices].apiKey = @"a2e716827857a145e86e99ea08cfe15f";        _mapView = [[MAMapView alloc] initWithFrame:[UIScreen mainScreen].bounds];    _mapView.mapType = MAMapTypeSatellite;// 设置地图样式，卫星    _mapView.showTraffic = YES; // 是否打开实时交通路况    _mapView.delegate = self;    _mapView.logoCenter = CGPointMake(CGRectGetWidth(self.view.bounds)-55, 450);// 设置地图logo的中心点    _mapView.showsCompass= YES; // 设置成 NO 表示关闭指南针;YES 表示显示指南针        _mapView.showsScale = YES; // 设置成 NO 表示不显示比例尺;YES 表示显示比例尺    _mapView.scaleOrigin= CGPointMake(_mapView.scaleOrigin.x, 22); // 设置比例尺位置    _mapView.compassOrigin= CGPointMake(_mapView.compassOrigin.x, 22); // 设置指南针位置    _mapView.showsUserLocation = YES; // 开启地图定位        [_mapView setUserTrackingMode:MAUserTrackingModeFollow animated:YES]; // 设置用户跟宗模式   }

6，添加标注

MAPointAnnotation *pointAnnotation = [[MAPointAnnotation alloc] init];//初始化标注    pointAnnotation.coordinate = CLLocationCoordinate2DMake(39.989631, 116.481018); //设置标注地理坐标    pointAnnotation.title = @"方恒国际";//设置标注标题    pointAnnotation.subtitle = @"阜通东大街 6 号";//设置标注子标题    [_mapView addAnnotation:pointAnnotation];//添加标注

- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id
     
      )annotation{        if ([annotation isKindOfClass:[MAPointAnnotation class]]) {            static NSString *pointReuseIndetifier = @"pointReuseIndetifier";            MAPinAnnotationView*annotationView = (MAPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndetifier];            if (annotationView == nil) {                annotationView = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pointReuseIndetifier];            }            annotationView.canShowCallout= YES; //设置气泡可以弹出,默认为 NO                    annotationView.animatesDrop = YES; //设置标注动画显示,默认为 NO            annotationView.draggable = YES; //设置标注可以拖动,默认为 NO annotationView.pinColor = MAPinAnnotationColorPurple;            return annotationView;        }        return nil;            }- (void)mapView:(MAMapView *)mapView didUpdateUserLocation:(MAUserLocation *)userLocation{//    NSLog("latitude : %f,longitude: %f",userLocation.coordinate.latitude,userLocation.coordinate.l ongitude);    NSLog(@"latitude : %f,longitude: %f", userLocation.coordinate.latitude,userLocation.coordinate.longitude);    }
     

7，编码、反编码

- (void)viewDidLoad {    [super viewDidLoad];        _search = [[AMapSearchAPI alloc] initWithSearchKey:@"a2e716827857a145e86e99ea08cfe15f" Delegate:self];  //初始化搜索    AMapGeocodeSearchRequest *georequest = [[AMapGeocodeSearchRequest alloc] init]; //构造一个request对象    georequest.searchType = AMapSearchType_Geocode; //设置为地理编码样式    georequest.address = @"北大"; //地址    georequest.city = @[@"北京"];//所在城市    [_search AMapGeocodeSearch:georequest]; //发起地理编码        // Do any additional setup after loading the view, typically from a nib.}#pragma mark 地理编码成功的回调- (void)onGeocodeSearchDone:(AMapGeocodeSearchRequest *)request response:(AMapGeocodeSearchResponse *)response{    if (response.count == 0) {        return;    }    NSString *string = [NSString stringWithFormat:@"%ld", response.count];    for (AMapTip *tip in response.geocodes) {
   //response.geocodes所有跟地址匹配的地点        NSLog(@"%@", [NSString stringWithFormat:@"%@", tip.description]);    }    }

_search = [[AMapSearchAPI alloc] initWithSearchKey:@"a2e716827857a145e86e99ea08cfe15f" Delegate:self];  //初始化搜索    AMapReGeocodeSearchRequest *georequest = [[AMapReGeocodeSearchRequest alloc] init]; //构造一个request对象    georequest.searchType = AMapSearchType_ReGeocode; //设置为反地理编码样式    georequest.location = [AMapGeoPoint locationWithLatitude:39.000 longitude:116.00];//设置所在地里位置的经纬度    georequest.radius = 1000;//搜索半径    georequest.requireExtension = YES;// 是否返回扩展信息，默认为 NO    [_search AMapGeocodeSearch:georequest]; //发起反地理编码#pragma mark 反地理编码成功- (void)onReGeocodeSearchDone:(AMapReGeocodeSearchRequest *)request response:(AMapReGeocodeSearchResponse *)response{    if (response.regeocode != nil) {        //处理搜索结果        NSString *result = [NSString stringWithFormat:@"%@", response.regeocode];    }}
