一、坐標點轉(zhuǎn)換
坐標分為：平面坐標、球面坐標(地理經(jīng)緯度)；在地圖應用上使用的平面坐標，如果拿到的是地理經(jīng)緯度坐標，那么是要進行轉(zhuǎn)換的
-(void)Convert{
//北緯N22°48′26.53″ 東經(jīng)E113°33′47.24″ ,拆分為：度 22 、分48、秒26.53
/*----先進行六十進制轉(zhuǎn)換 WGS84坐標----*/
double s = 26.53/60;
double f = ( 48 + s )/60;
double lat = 22 + f;
//這時候 c 是 WGS84：為一種大地坐標系，也是目前廣泛使用的GPS全球衛(wèi)星定位系統(tǒng)使用的坐標系；
//百度地圖SDK在國內(nèi)（包括港澳臺）使用的是BD09坐標；在海外地區(qū)，統(tǒng)一使用WGS84坐標
/*----BD09坐標轉(zhuǎn)換----*/
//下面是百度官方提供的轉(zhuǎn)換，每應用提供轉(zhuǎn)換是不一樣的，雖然是同一個地方，但是轉(zhuǎn)換后的坐標點是不一樣的，這里轉(zhuǎn)換后的坐標點只適用百度地圖
CLLocationCoordinate2D coor = CLLocationCoordinate2DMake(lat,lon);//原始坐標
//轉(zhuǎn)換國測局坐標（google地圖、soso地圖、aliyun地圖、mapabc地圖和amap地圖所用坐標）至百度坐標
NSDictionary* testdic = BMKConvertBaiduCoorFrom(coor,BMK_COORDTYPE_COMMON);
//轉(zhuǎn)換WGS84坐標至百度坐標(加密后的坐標)
testdic = BMKConvertBaiduCoorFrom(coor,BMK_COORDTYPE_GPS);
//解密加密后的坐標字典
CLLocationCoordinate2D baiduCoor = BMKCoorDictionaryDecode(testdic);
double y = baiduCoor.latitude;
double x = baiduCoor.longitude;
NSLog(@"百度地圖BD09坐標 --- %f,%f",y,x);
}
二、添加坐標點、數(shù)據(jù)
-(void)onClickReverseGeocode
{
array_description = [NSMutableArray array];
for (int i = 0; i< 5; i++) {
MapPointModel * model = [MapPointModel new]; //
model.lat = 23.195090+(i*0.00002);
model.lon = 113.260530;
model.title = [NSString stringWithFormat:@"坐標：%d",I];
[array_description addObject:model];
}
[self addPointJuheWithCoorArray:array_description]; //添加模型數(shù)組
}
三、添加模型數(shù)組
NSMutableArray *_clusterCaches;//點聚合緩存標注
BMKClusterManager *_clusterManager;//點聚合管理類
- (void)addPointJuheWithCoorArray:(NSArray *)array {
_clusterCaches = [[NSMutableArray alloc] init];
for (NSInteger i = 3; i < 22; i++) {
[_clusterCaches addObject:[NSMutableArray array]];
}
//點聚合管理類
_clusterManager = nil;
_clusterManager = [[BMKClusterManager alloc] init];
for (int i = 0; i <array.count; i++) {
MapPointModel * model = array[i];
BMKClusterItem *clusterItem = [[BMKClusterItem alloc] init];
clusterItem.coor = CLLocationCoordinate2DMake(model.lat, model.lon);
clusterItem.model = model;
[self->_clusterManager addClusterItem:clusterItem];
}
[self updateClusters]; //更新聚合狀態(tài)
}
四、更新聚合狀態(tài)
NSInteger _clusterZoom;//聚合級別
BMKMapView * _mapView;
- (void)updateClusters {
_clusterZoom = (NSInteger)_mapView.zoomLevel;
@synchronized(_clusterCaches) {
__block NSMutableArray *clusters = [_clusterCaches objectAtIndex:(_clusterZoom - 3)];
if (clusters.count > 0) {
[_mapView removeAnnotations:_mapView.annotations];
[_mapView addAnnotations:clusters];
} else {
dispatch_async(dispatch_get_global_queue(0, 0), ^{
///獲取聚合后的標注
__block NSArray *array = [self->_clusterManager getClusters:self->_clusterZoom];
dispatch_async(dispatch_get_main_queue(), ^{
//聚合后的數(shù)組
for (BMKCluster *item in array) {
FateMapAnnotation *annotation = [[FateMapAnnotation alloc] init];
annotation.coordinate = item.coordinate;
annotation.size = item.size;
annotation.cluster = item;
if (item.size == 1) { //坐標點沒有重疊的時候
BMKClusterItem *clusterItem = item.clusterItems[0];
MapPointModel * model = clusterItem.model;
annotation.title = model.title;
}
annotation.title = [NSString stringWithFormat:@"我是%lu個", (unsigned long)item.size];
[clusters addObject:annotation];
}
[self->_mapView removeAnnotations:self->_mapView.annotations];
[self->_mapView addAnnotations:clusters];
});
});
}
}
}
//地圖改變的時候發(fā)送請求
- (void)mapView:(BMKMapView *)mapView regionDidChangeAnimated:(BOOL)animated {
//
[self updateClusters];
}
- (void)mapViewDidFinishLoading:(BMKMapView *)mapView {
[self updateClusters];
}
- (BMKAnnotationView *)mapView:(BMKMapView *)view viewForAnnotation:(id <BMKAnnotation>)annotation{
// 生成重用標示identifier
FateMapAnnotation *cluster = (FateMapAnnotation*)annotation;
NSString *AnnotationViewID = @"xidanMark";
// 檢查是否有重用的緩存
FateMapAnnotationView* annotationView = (FateMapAnnotationView*)[view dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];
// 緩存沒有命中，自己構造一個，一般首次添加annotation代碼會運行到此處
if (annotationView == nil) {
annotationView = [[FateMapAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];
annotationView.paopaoView = nil;
}
annotationView.size = cluster.size;
annotationView.cluster = cluster.cluster;
annotationView.annotation = cluster;
annotationView.centerOffset = CGPointMake(0, -(annotationView.frame.size.height * 0.5));
// 單擊彈出泡泡，彈出泡泡前提annotation必須實現(xiàn)title屬性
annotationView.canShowCallout = YES;
//cluster.size 當前聚合狀態(tài)坐標系個數(shù)，當一個的時候給它做一些你想要做的事情??
if (cluster.size == 1 ) { //其中一個點只有一個坐標，添加點擊彈出的泡泡View
