推荐答案

如果您的意思是基于两点将用户带到地图应用程序，那么您可以这样做： p>

If you mean taking the user to the maps application based on two points, then you can do it like this:

1. 创建一个如下所示的NSURL：
   NSURL * URL = [NSURL URLWithString：@http： //maps.google.com/maps?saddr=%f,%f&daddr=%f,%f];
   您插入起始地址和目的地（以lat 。和适当的。）。


2. 告诉您的应用程序打开URL
   [[UIApplication sharedApplication] openURL：URL];

1. Create an NSURL that looks like this: NSURL *URL = [NSURL URLWithString:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f"]; You plug in your starting address and destination (in lat. and long.) appropriately.
2. Tell your application to open the URL [[UIApplication sharedApplication] openURL:URL];

它会自动带您到地图应用程序！

It should take you to the maps application automatically!
