關(guān)于怎么導(dǎo)入百度地圖SDK與創(chuàng)建應(yīng)用就不多說(shuō)了，百度的文檔應(yīng)該比我說(shuō)的更詳細(xì)，下面直接正文吧：

1.首先地圖的初始化

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
}

- (void)setupView {

    /// 地圖
    _mapView = [[BMKMapView alloc]init];
    
    [_mapView setMapType:BMKMapTypeStandard];// 地圖類(lèi)型 ->衛(wèi)星／標(biāo)準(zhǔn)、
    _mapView.showsUserLocation = YES;
    _mapView.gesturesEnabled = YES;
    _mapView.delegate = self; // 此處記得不用的時(shí)候需要置nil，否則影響內(nèi)存的釋放
    _mapView.frame = self.view.bounds;
    [self.view addSubview:_mapView];
}
// 地圖的初始化
- (void)setupMapService {
    _locService = [[BMKLocationService alloc]init];
    _locService.delegate = self;
    _locService.desiredAccuracy =  kCLLocationAccuracyBest;
    _locService.distanceFilter = 10;//大于100米
    [_locService startUserLocationService];
    
    _geoCodeSerch = [[BMKGeoCodeSearch alloc] init];
    _geoCodeSerch.delegate = self;
    
    _mapView.showsUserLocation = NO;//先關(guān)閉顯示的定位圖層
    _mapView.userTrackingMode = BMKUserTrackingModeFollow;//設(shè)置定位的狀態(tài)
    _mapView.showsUserLocation = YES;//顯示定位圖層
    
    _clusterManager = [[BMKClusterManager alloc] init];
    
    //初始化檢索對(duì)象
    self.districtSearch = [[BMKDistrictSearch alloc] init];
    //設(shè)置delegate，用于接收檢索結(jié)果
    self.districtSearch.delegate = self;
    
    //在此處理正常結(jié)果
    _clusterCaches = [[NSMutableArray alloc] init];
    for (NSInteger i = 3; i < 22; i++) {
        [_clusterCaches addObject:[NSMutableArray array]];
    }
}

2.地圖的開(kāi)始與加載完畢

/**
 *地圖初始化完畢時(shí)會(huì)調(diào)用此接口
 *@param mapView 地圖View
 */
- (void)mapViewDidFinishLoading:(BMKMapView *)mapView {
    BMKLocationViewDisplayParam *displayParam = [[BMKLocationViewDisplayParam alloc]init];
    displayParam.isAccuracyCircleShow = NO;//精度圈是否顯示
    [_mapView updateLocationViewWithParam:displayParam];
    
    BMKCoordinateRegion region ;//表示范圍的結(jié)構(gòu)體
    region.center = _mapView.centerCoordinate;//中心點(diǎn)
    self.cCoordinate = _mapView.centerCoordinate;//中心點(diǎn)
    region.span.latitudeDelta = 0.002;//經(jīng)度范圍（設(shè)置為0.1表示顯示范圍為0.2的緯度范圍）
    region.span.longitudeDelta = 0.002;//緯度范圍
    [_mapView setRegion:region animated:YES];
    [self updateClusters];
}

/**
 *地圖渲染每一幀畫(huà)面過(guò)程中，以及每次需要重繪地圖時(shí)（例如添加覆蓋物）都會(huì)調(diào)用此接口
 *@param mapView 地圖View
 *@param status 此時(shí)地圖的狀態(tài)
 */
- (void)mapView:(BMKMapView *)mapView onDrawMapFrame:(BMKMapStatus *)status {
    if (_clusterZoom != 0 && _clusterZoom != (NSInteger)mapView.zoomLevel) {
        [self updateClusters];
    }
}

3.地圖的位置發(fā)生變化

- (void)mapView:(BMKMapView *)mapView regionDidChangeAnimated:(BOOL)animated {
    //屏幕坐標(biāo)轉(zhuǎn)地圖經(jīng)緯度
    CLLocationCoordinate2D MapCoordinate = [_mapView convertPoint:_mapView.center toCoordinateFromView:_mapView];
    
    if (_reverseGeoCodeOption==nil) {
        //初始化反地理編碼類(lèi)
        _reverseGeoCodeOption= [[BMKReverseGeoCodeOption alloc] init];
    }
    
    //需要逆地理編碼的坐標(biāo)位置
    _reverseGeoCodeOption.reverseGeoPoint =MapCoordinate;
    [_geoCodeSerch reverseGeoCode:_reverseGeoCodeOption];
   // 如果你是請(qǐng)求自己后臺(tái)的數(shù)據(jù)可以在這里請(qǐng)求，可以省去下面檢索回來(lái)的數(shù)據(jù)，由于我的是demo，所以下面是必須要的
    BMKNearbySearchOption *option = [[BMKNearbySearchOption alloc]init];
    option.pageIndex = 1;
    option.pageCapacity = 10;
    option.location = mapView.centerCoordinate;
    
    option.keyword = @"小吃";
    BOOL flag = [self.poiSearch poiSearchNearBy:option];
    if(flag)
    {
        NSLog(@"周邊檢索發(fā)送成功");
    }
    else
    {
        NSLog(@"周邊檢索發(fā)送失敗");
    }
}

// 當(dāng)?shù)貓D發(fā)生改變之后，檢索并
//實(shí)現(xiàn)PoiSearchDeleage處理回調(diào)結(jié)果
- (void)onGetPoiResult:(BMKPoiSearch*)searcher result:(BMKPoiResult*)poiResultList errorCode:(BMKSearchErrorCode)error
{
    if (error == BMK_SEARCH_NO_ERROR) {
        //在此處理正常結(jié)果
    }
    else if (error == BMK_SEARCH_AMBIGUOUS_KEYWORD){
        //當(dāng)在設(shè)置城市未找到結(jié)果，但在其他城市找到結(jié)果時(shí)，回調(diào)建議檢索城市列表
        // result.cityList;
        NSLog(@"起始點(diǎn)有歧義");
    } else {
        NSLog(@"抱歉，未找到結(jié)果");
    }
    // 清空緩存數(shù)據(jù)
    [_clusterManager clearClusterItems];
    for (BMKPoiInfo *poiInfo in poiResultList.poiInfoList) {
        XJCluster *cluster = [[XJCluster alloc] init];
        cluster.name = poiInfo.name;
        cluster.pt = poiInfo.pt;
        // 添加數(shù)據(jù)
        [self addAnnoWithPT:cluster];
    }
}

4.更新點(diǎn)聚合狀態(tài)

//更新聚合狀態(tài)
- (void)updateClusters {
 
    _clusterZoom = (NSInteger)_mapView.zoomLevel;
    @synchronized(_clusterCaches) {
        
            NSMutableArray *clusters = [NSMutableArray array];
            dispatch_async(dispatch_get_global_queue(0, 0), ^{
                ///獲取聚合后的標(biāo)注
                __block NSArray *array = [_clusterManager getClusters:_clusterZoom];
        
                dispatch_async(dispatch_get_main_queue(), ^{
                    for (BMKCluster *item in array) {
                        XJClusterAnnotation *annotation = [[XJClusterAnnotation alloc] init];
                        annotation.coordinate = item.coordinate;
                        annotation.size = item.size;
                        annotation.title = item.title;
                        annotation.cluster = item.cluster;
                        [clusters addObject:annotation];
                    }
                    [_mapView removeOverlays:_mapView.overlays];
                    [_mapView removeAnnotations:_mapView.annotations];
                    [_mapView addAnnotations:clusters];

                });
            });
        }
}
