推荐答案

据我所知，没有公共可用的API来缓存MKMapView使用的地图图像.这样做可能还会违反Google的条款和条件.

As far as I know, there is no public available API for caching the map images used by MKMapView. You might also be in violation of Googles terms and conditions by doing this.

但是，Google提供了静态地图API ，抓取地图的静态部分作为图像文件，并可能将其缓存以供以后显示.但是再次，请检查Google的条款与条件.

However, Google have provided a static map API where you can grab a static portion of a map as an image file and possible cache this for later display. But again, check Google's T&C.

通过 SO问题，显示了有关如何使用这些API的一些提示.

There are a number of other map services available through the GData API, but they are somewhat more complex to use. This SO question, shows a few hints on how to use these API's.
