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<MAAnnotation>)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];
    }
}
