每个经纬度谷歌地图ios的markerinfowindow

我有经纬度和从API获得的其他信息，但我想动态显示

markerinfowindow

，并显示一些信息，如名称和编号

if ([response count]>0)
     {
         NSArray *array = [response valueForKey:@"response"];

         for (int i=0; i<[array count]; i++)
         {
             [arrayLat addObject:[[[response valueForKey:@"response"] objectAtIndex:i] valueForKey:@"lat"]];
             [arrLong addObject:[[[response valueForKey:@"response"] objectAtIndex:i] valueForKey:@"longi"]];
             position = CLLocationCoordinate2DMake([[arrayLat objectAtIndex:i]floatValue],[[arrLong objectAtIndex:i]floatValue]);
             GMSMarker  *marker = [GMSMarker markerWithPosition:position];
             //marker.title = [titlearr objectAtIndex:i];
             // marker.snippet = @"Subtitle";
             marker.flat=YES;
             marker.map = mapView;
             mapView.delegate = self;
             //marker.title=[[[response valueForKey:@"response"] objectAtIndex:i] valueForKey:@"firstname"];
             marker.icon = [GMSMarker markerImageWithColor:[UIColor redColor]];
             mapView.delegate = self;
         }
     }

您可以使用GMSMarker的属性userData

示例：您有如下数据

json = [{"id":1,"name":"demo", "city":"BOTAD"},{"id":2,"name":"demo2", "city":"SURAT"}]

如果您想显示BOTAD的数据，那么将userData设置为

GMSMarker *marker = [[GMSMarker alloc] init];
marker.userData = [json objectAtIndex:0];

在这之后，您可以在委托方法下获得它，如

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker
{
    NSDictionary *data = marker.userData;

    return mapView;
}

现在很容易从字典中获取城市和名称等数据，您可以在标签上设置文本

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker
{
    NSDictionary *data = marker.userData;

    return mapView;
}
