使用地图应用iOS生成步行路线 [英] Generate walking directions with Maps app iOS

问题描述

  NSString * formattedGroceryAddress =我的应用程序使用地图应用程序 [[NSString stringWithFormat：@％@，（（EnhancedUIActionSheet *）actionSheet）.grocery.address] stringByReplacingOccurrencesOfString：@withString：@+]; 
 NSString * routeString = [NSString stringWithFormat：@http://maps.google.com/maps?saddr=%f,%f&daddr=%@，localDataHelper.userLocation.coordinate.latitude，localDataHelper。 userLocation.coordinate.longitude，formattedGroceryAddress]; 
 [[UIApplication sharedApplication] openURL：[NSURL URLWithString：routeString]]; 
  

使用适当的驾车指示打开地图应用。问题是，我想默认情况下打开地图步行指示。也许我可以在我的请求中传递另一个参数来做到这一点。

任何人都知道如何？

谢谢！ / p>

解决方案

好吧，我想我应该在查询之前进行更好的搜索！

您可以将dirflg = w添加到请求中，并且它将以步行模式启动地图应用程序。

这很有趣，因为Apple表示他们只支持少数Google地图参数包括这一个，但它似乎工作！

As of now, I successfully generate directions with Maps app from my app with the following code :

NSString *formattedGroceryAddress = [[NSString stringWithFormat:@"%@",((EnhancedUIActionSheet *)actionSheet).grocery.address] stringByReplacingOccurrencesOfString:@" " withString:@"+"];
NSString *routeString = [NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%@",localDataHelper.userLocation.coordinate.latitude,localDataHelper.userLocation.coordinate.longitude,formattedGroceryAddress];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:routeString]];

It opens the Maps app with the appropriate driving directions. The thing is, I'd like to open Maps with the walking directions by default. Maybe I can pass another parameter in my request to do that.

Anybody knows how ?

Thanks !

解决方案

Well I guess I should have searched better before asking !

You can add dirflg=w to the request and it will launch maps app in the walking mode.

It's funny because Apple says they are only supporting a few Google Maps parameters not including this one but it actually seems to work !
