随手写一个DEMO：

- (void)viewDidLoad

{

[super viewDidLoad];

_search = [[BMKSearch alloc]init];

_search.delegate = self;

// 设置地图级别

[_mapView setZoomLevel:13];

_mapView.isSelectedAnnotationViewFront = YES;

//发起POI检索

BOOL flag = [_search poiSearchInCity:@"武汉" withKey:@"武汉协和医院" pageIndex:0];

if(flag){

NSLog(@"success!");

}else{

NSLog(@"error!");

}

}

- (void)onGetPoiResult:(NSArray*)poiResultList searchType:(int)type errorCode:(int)error

{

// 清楚屏幕中所有的annotation

NSArray* array = [NSArray arrayWithArray:_mapView.annotations];

[_mapView removeAnnotations:array];

BMKPointAnnotation* item = [[BMKPointAnnotation alloc]init];

// 30.5907940162,114.2823383453

CLLocationCoordinate2D coor;

coor.latitude = 30.5907940162;

coor.longitude = 114.2823383453;

item.coordinate = coor;

item.title = @"武汉协和医院";

[_mapView addAnnotation:item];

_mapView.centerCoordinate = coor;

}

/**

*根据anntation生成对应的View

*@param mapView 地图View

*@param annotation 指定的标注

*@return 生成的标注View

*/

- (BMKAnnotationView *)mapView:(BMKMapView *)view viewForAnnotation:(id )annotation

{

// 生成重用标示identifier

NSString *AnnotationViewID = @"xieheMark";

// 检查是否有重用的缓存

BMKAnnotationView* annotationView = [view dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];

// 缓存没有命中，自己构造一个，一般首次添加annotation代码会运行到此处

if (annotationView == nil) {

annotationView = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];

((BMKPinAnnotationView*)annotationView).pinColor = BMKPinAnnotationColorRed;

// 设置重天上掉下的效果(annotation)

((BMKPinAnnotationView*)annotationView).animatesDrop = YES;

}

// 设置位置

annotationView.centerOffset = CGPointMake(0, -(annotationView.frame.size.height * 0.5));

annotationView.annotation = annotation;

// 单击弹出泡泡，弹出泡泡前提annotation必须实现title属性

annotationView.canShowCallout = YES;

// 设置是否可以拖拽

annotationView.draggable = NO;

return annotationView;

}
