iOS:如何使用自定义信息窗口动态创建 GMSMarker？

Question

我通过for循环创建了GMSMarker，但是GMSMarker不支持标签

for(int i=0;i<[self.shopDetailArray count];i++)
    {
        SHShopLocator *shop = [self.shopDetailArray objectAtIndex:i];

        GMSMarker *marker = [[GMSMarker alloc] init];
        marker.position = CLLocationCoordinate2DMake(22.2783, 114.1589);
        marker.icon = [UIImage imageNamed:@"StoreLocator_pin"];
        marker.infoWindowAnchor = CGPointMake(0.3, 0.4);
        marker.map = self.map;
    }

那么在设置自定义 markerInfoWindow 时如何识别每个标记？

  - (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker

Answer 1

您可以使用 GMSMarker 的属性 userData。您可以为每个标记存储标识符!

例子

GMSMarker *marker = [[GMSMarker alloc] init];
marker.userData = @{@"marker_id":[NSNumber numberWithInt:12]};

检索其值:

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker
{
    NSNumber *number = [marker.userData objectForKey:@"marker_id"];

    return mapView;
}

Marker data. You can use this property to associate an arbitrary object with this marker. Google Maps SDK for iOS neither reads nor writes this property. Note that userData should not hold any strong references to any Maps objects, otherwise a loop may be created (preventing ARC from releasing objects).
