百度地图大头针图片的自定义

重写此方法即可实现大头针图片的替换:

- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation

即代码：

- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation{    if ([annotation isKindOfClass:[BMKPointAnnotation class]]) {        BMKPinAnnotationView *newAnnotationView = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"myAnnotation"];        newAnnotationView.pinColor = BMKPinAnnotationColorPurple;        newAnnotationView.animatesDrop = YES;// 设置该标注点动画显示        newAnnotationView.annotation=annotation;        newAnnotationView.image = [UIImage imageNamed:@"dfh"];   //把大头针换成别的图片        return newAnnotationView;    }    return nil;}

另外，如果同一个地图中添加的大头针的图片不同，可通过下属方法解决：
例如现在是两种大头针：
可以声明两个大头针的成员变量：

 BMKPointAnnotation* pointAnnotation;     BMKPointAnnotation* animatedAnnotation;

其中，想让animatedAnnotation添加原生的大头针图片，pointAnnotation给换成自己想要添加的大头针图片，在添加animatedAnnotation类的大头针时，按正常添加即可：

animatedAnnotation = [[BMKPointAnnotation alloc]init];    animatedAnnotation.coordinate = userLocation.location.coordinate;    animatedAnnotation.title = @"当前位置";    [_mapView addAnnotation:animatedAnnotation];

而对于想要改变图片的大头针：

-(void)addAnnotationWith:(NSDictionary *)dic {    NSLog(@"添加大头针");    //添加大头针    pointAnnotation = [[BMKPointAnnotation alloc]init];    pointAnnotation.coordinate = coorOfLocation;    CLLocationCoordinate2D coor;    coor.latitude = [[NSString stringWithFormat:@"%@",[dic objectForKey:@"latitude"]] floatValue];    coor.longitude = [[NSString stringWithFormat:@"%@",[dic objectForKey:@"longitude"]] floatValue];    pointAnnotation.coordinate = coor;    NSLog(@"%f======%f",pointAnnotation.coordinate.latitude,pointAnnotation.coordinate.longitude);    pointAnnotation.title = @"司机当前位置";    [_mapView setCenterCoordinate:coor animated:YES];    [_mapView addAnnotation:pointAnnotation];}//实现大头针图片的修改- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation{    if (annotation == pointAnnotation) {//加一个判断即可实现将pointAnnotation类的大头针的图片修改        NSString *AnnotationViewID = @"renameMark";        BMKPinAnnotationView *annotationView = (BMKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];        if (annotationView == nil) {            annotationView = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];            // 设置颜色            annotationView.pinColor = BMKPinAnnotationColorPurple;            annotationView.annotation=annotation;            annotationView.image = [UIImage imageNamed:@"place1"];   //把大头针换成别的图片        }        return annotationView;    }    return nil;}
