GMUrlSigner

This example provides a function for generating the URL of signatures required for Google Maps API web service (business account) calls in Objective-C projects.

The original code is available here.

I simply took the necessary code to the URL signature generation and use it in a simple way.

You can test the generated signature with this tool
