Link to iPhone map App from HTML page

Question

Is there a way to link to directions in the iPhone map app from a html page?

We\'re placing an add in an iPhone app which will link to a mobile page on our website -

Answer 1

Here is a javascript function that creates the link:

function mapLink(myAddress) {
    return 'http://maps.google.com/maps?q='+escape(myAddress);
}

This works great on the iPhone.

Answer 2

Use something like:

<a href='maps:daddr=<destination>&saddr=Current%20Location'>Directions</a>

where may be a lat/lon pair (separated by a comma) or a place. Ensure you URI encode the destination to ensure it works.

Answer 3

A link to http://maps.google.com/maps will automatically open in the map application

You can set a destination address (daddr) and start address (saddr) in the link:

http://maps.google.com/maps?daddr=San+Francisco,+CA&saddr=cupertino

Answer 4

If you use the standard link that would display a map in the browser, it will automatically open in Google Maps on the device. That includes links that show directions.
