开启定位

    // 配置用户Key
    [MAMapServices sharedServices].apiKey = AmapKey;
    // 创建地图
    _mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.bounds))];
    _mapView.delegate = self;
    // 隐藏罗盘
    _mapView.showsCompass = NO;
    [self.view addSubview:_mapView];
    
    // 定位
    _mapView.showsUserLocation = YES;
    // 设置定位模式
    _mapView.userTrackingMode = MAUserTrackingModeFollow;
    // 设置缩放比例
    [_mapView setZoomLevel:16.1 animated:NO];

地图移动到某一坐标点

[_mapView setCenterCoordinate:_myCoordinate animated:YES];

设置我的位置显示的位置信息

    // 设置气泡显示信息
    _mapView.userLocation.title = @"sodded";
    // 默认弹出气泡，显示位置信息
    [_mapView selectAnnotation:_mapView.annotations[0] animated:YES];

逆地理编码

#import <AMapSearchKit/AMapSearchKit.h>
 
@interface ViewController ()<AMapSearchDelegate>
{
    AMapSearchAPI *_search;
}
@end
 
-(void)viewDidLoad 
{
    //配置用户Key
    [AMapSearchServices sharedServices].apiKey = @"用户Key";
 
    //初始化检索对象 
    _search = [[AMapSearchAPI alloc] init];
    _search.delegate = self;
     
    //构造AMapReGeocodeSearchRequest对象
    AMapReGeocodeSearchRequest *regeo = [[AMapReGeocodeSearchRequest alloc] init];
    regeo.location = [AMapGeoPoint locationWithLatitude:39.990459     longitude:116.481476];
    regeo.radius = 10000;
    regeoRequest.requireExtension = YES;
 
    //发起逆地理编码
    [_search AMapReGoecodeSearch: regeo];
 
}
 
//实现逆地理编码的回调函数
- (void)onReGeocodeSearchDone:(AMapReGeocodeSearchRequest *)request response:(AMapReGeocodeSearchResponse *)response
{
    if(response.regeocode != nil)
    {
        //通过AMapReGeocodeSearchResponse对象处理搜索结果
        NSString *result = [NSString stringWithFormat:@"ReGeocode: %@", response.regeocode];
        NSLog(@"ReGeo: %@", result);
    }
}

周边搜索

#import <AMapSearchKit/AMapSearchKit.h>
 
@interface ViewController ()<AMapSearchDelegate>
{
    AMapSearchAPI *_search;
}
@end
 
-(void)viewDidLoad 
  {   
    //配置用户Key
    [AMapSearchServices sharedServices].apiKey = @"用户Key";
 
    //初始化检索对象 
    _search = [[AMapSearchAPI alloc] init];
    _search.delegate = self;
     
    //构造AMapPOIAroundSearchRequest对象，设置周边请求参数
    AMapPOIAroundSearchRequest *request = [[AMapPOIAroundSearchRequest alloc] init];
    request.location = [AMapGeoPoint locationWithLatitude:39.990459 longitude:116.481476];
    request.keywords = @"方恒";
    // types属性表示限定搜索POI的类别，默认为：餐饮服务|商务住宅|生活服务
    // POI的类型共分为20种大类别，分别为：
    // 汽车服务|汽车销售|汽车维修|摩托车服务|餐饮服务|购物服务|生活服务|体育休闲服务|
    // 医疗保健服务|住宿服务|风景名胜|商务住宅|政府机构及社会团体|科教文化服务|
    // 交通设施服务|金融保险服务|公司企业|道路附属设施|地名地址信息|公共设施
    request.types = @"餐饮服务|生活服务";
    request.sortrule = 0;
    request.requireExtension = YES;
     
    //发起周边搜索
    [_search AMapPOIAroundSearch: request];
}
 
//实现POI搜索对应的回调函数
- (void)onPOISearchDone:(AMapPOISearchBaseRequest *)request response:(AMapPOISearchResponse *)response
{
    if(response.pois.count == 0)
    {
        return;
    }
     
    //通过 AMapPOISearchResponse 对象处理搜索结果
    NSString *strCount = [NSString stringWithFormat:@"count: %d",response.count];
    NSString *strSuggestion = [NSString stringWithFormat:@"Suggestion: %@", response.suggestion];
    NSString *strPoi = @"";
    for (AMapPOI *p in response.pois) {
        strPoi = [NSString stringWithFormat:@"%@\nPOI: %@", strPoi, p.description];
    }
    NSString *result = [NSString stringWithFormat:@"%@ \n %@ \n %@", strCount, strSuggestion, strPoi];
    NSLog(@"Place: %@", result);
}

自定义标注

1、实现<MAMapViewDelegate>代理
2、实现代理方法：

//返回自定义标注
- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)annotation
{
    if ([annotation isKindOfClass:[MAPointAnnotation class]])
    {
        static NSString *reuseIndetifier = @"annotationReuseIndetifier";
        MAAnnotationView *annotationView = (MAAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:reuseIndetifier];
        if (annotationView == nil)
        {
            annotationView = [[MAAnnotationView alloc] initWithAnnotation:annotation
                                                          reuseIdentifier:reuseIndetifier];
        }
        //标注图片
        annotationView.image = [UIImage imageNamed:@"160-pin-blue"];
        //设置中心点偏移，使得标注底部中间点成为经纬度对应点
        annotationView.centerOffset = CGPointMake(0, -24);
        //设置气泡可以弹出，默认为NO
        annotationView.canShowCallout= YES;
        //设置标注可以拖动，默认为NO
        annotationView.draggable = YES;
        
        return annotationView;
    }
    return nil;
}

3、添加标注

MAPointAnnotation *pointAnnotation = [[MAPointAnnotation alloc] init];
        pointAnnotation.coordinate = CLLocationCoordinate2DMake(39.989631, 116.481018);
        pointAnnotation.title = @"方恒国际";
        pointAnnotation.subtitle = @"阜通东大街6号";
        
        [_mapView addAnnotation:pointAnnotation];

移除地图上所有标注

//移除所有标注
    [_mapView removeAnnotations:_mapView.annotations];
