我正在使用地图样式器，我试图隐藏所有小城市的标签。问题是他们都被列为地方。所以，如果我关闭＆＃34; featureType＆＃34;：＆＃34; locality＆＃34;它甚至关闭了大城市。
请查看此谷歌地图链接中的位置，您将看到缩小较大城市的位置，例如＆＃39; Brasilia＆＃39;和戈亚尼亚＆＃39;有一个更大更大胆的标签。而其他较小的城市周围有较小的字体大小标签。
因此，默认情况下，谷歌地图显然会以不同的方式为不同规模的城市设置样式。
我如何为那些较小的城市标签创建自己的风格？
我尝试了＃34; featureType＆＃34;：＆＃34; locality.sub_locality＆＃34;但它隐藏了包括大城市在内的所有地方。
答案 0 :(得分：2)
一种选择是隐藏所有地区（＆＃34; locality.sub_locality＆＃34;），然后为您想要显示的大城市添加自己的标签。
