高德地图自定义坐标

引入framework 实现下面这个代理方法

// Override
- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id )annotation
{
    if ([annotation isKindOfClass:[MAPointAnnotation class]])
    {
        static NSString *reuseIndetifier = @"annotationReuseIndetifier";
        PointAnnotationView *annotationView = (PointAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:reuseIndetifier];
        if (annotationView == nil)
        {
            annotationView = [[PointAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:reuseIndetifier];
        }
        
        annotationView.image = [UIImage imageNamed:@"targetPoint"];
        
        NSString * result = [[annotation title] stringByReplacingOccurrencesOfString:@"点标" withString:@""]; //截取字符串
        result = [result stringByReplacingOccurrencesOfString:@"点" withString:@""];
        annotationView.point_ID.text = [result stringByReplacingOccurrencesOfString:@"号" withString:@""];
        //        annotationView.point_url = self.gameInfo.img_url;
        //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, -18);
        annotationView.canShowCallout = NO;
        return annotationView;
    }
    
    return nil;
}
