我正在执行基于地图基的申请。 我需要澄清的是,当我们聚集在地图上/在地图上外时,有可能获得地图意见的高度或动物。 因为基于这一点,我需要说一些事件。 请就此帮助我。
Thanks in advance, Sekhar Bethalam.
你们能够看到你地图显示的面积有多少。 通过对<代码>区域财产的检查。
map.region.span.latitudeDelta
该地图在纬度上达到目前的高度。 纬度约为69英里(即111公里)。
map.region.span.longitudeDelta
将给你长度地绘制地图,但认识到,长度线并不平行,范围因距离赤道而异。 海事组织处理第一个参数的工作非常容易。
