Is there a way to place a pin into the google maps iphone app using openURL?

Question

I would like to create an iPhone app that can open the google maps app and place a pin on the map.

I have the exact location of the pin, specified by its longitude and latitude. I also have a name for the pin e.g. 'location 1' that should be displayed along with the pin.

I know that UIApplication:openURL can be used for this but I don't know the exact url format.

So, is there a way to do what I described above? If, yes, what is the correct url format?

Answer 1

You can use a URL of the format: http://maps.google.com/maps?q=Your+Location+name@latitude,longitude

http://maps.google.com/[email protected],-87.6315

Answer 2

You can drop up to 100 pins using KML. There is an example of this on http://appsamuck.com look at the example for day 8 (http://appsamuck.com/day8.html)
