openURL maps link specify current location????

simsimma · 10-07-2008, 02:43 AM

Hello,

In my application I construct an openURL link as follows:

Code:

http://maps.google.com/daddr=37.74324,-121.43432&saddr=Current&Location

What I'm trying to accomplish is to launch Google Maps on the iPhone so that it finds directions from the Current Location to the destination latitude and longitude.

However, specifying the current location as above does not work. How can I take advantage of Google Maps's inbuilt current location finding to get these directions? Is there some special syntax I am missing?

are you asking how to use the iPhones GPS/triangulation?

CoreLocation

take a look at the LocateMe sample on the apple dev site.

Hi, thanks for the quick reply.

I know how to use Core Location.

The issue is that on the "Maps" application I can get driving directions by specifying my source address as "Current Location." Type it in to the source text field and you'll see we can get driving directions between source and destination.

I want to create an openURL link that takes advantage of that. Reason? Using coreLocation often takes 5-8 seconds to get a reasonably accurate fix. If I can hand that off to Google Maps rather than to my application, my application runs faster.

Use the &ll= parameter.

Hi, but the problem but the &ll parameter is that it only centers the map at that point. It doesn't give you the directions automatically...

Any other ideas?

Use &saddr= and &daddr= then.

I think what he's asking is how to send a URL to the Maps application that takes advantage of the "Current Location" bookmark. I, too, would like to do this; has anyone figured out a way?

I am having the same problems open the maps with a given route.

Any solutions?

Cheers

Can you get the current location from coreLocation, and pass that as the saddr? Does that work? This URL works for me on my phone (OS 2.2, openURL) :

Code:

http://maps.google.com/maps?daddr=37.74324,-121.43432&saddr=37.5,-121.4

(Your URL didn't have "maps?" in it.)

I'm trying to figure this out too, did anyone crack it?

Also need his info

sagimann · 08-06-2010, 09:43 AM

same problem here... the approach of first using Core location to get the current location is not good enough, because if the location detected is not accurate enough, and you're driving by car, for example, you really need to have the maps app continue to try and get a more accurate position. So, I am, too, looking for a way to use the "current location" bookmark from a URL...

any ideas?

tnx
