My IronCoder entry for c4[2]: a clean-room implementation of Apple’s CoreLocation.framework, complete with sample application.
\n<\/h3>\n
http:\/\/developer.casgrain.com\/files\/DesktopCoreLocation.zip<\/a><\/p>\n
Description<\/h4>\n
\nThis is a clean-room implementation of Apple’s CoreLocation framework that is part of the iPhone SDK.<\/p>\n
\nIt uses Apple’s own headers, which are installed when you install the iPhone SDK, as the interface, and implements all the functionality of CoreLocation in an embeddable framework.<\/p>\n
\nIt can be made a system-wide framework buy changing its executable path from @loader_path\/..\/Frameworks\/<\/code> to \/Library\/Frameworks<\/code>.<\/p>\n
\nThe Desktop and Phone sample applications are very similar: they both demonstrate using CoreLocation.framework.<\/p>\n
How it works<\/h4>\n
The framework figures out your current, internet-facing IP address using whatismyip.com<\/a>. It then uses basic IP Geolocation<\/a> web services to extract latitude and longitude. Results are cached 30 days for each IP address.<\/p>\n
\nThere are certainly other IP geolocation services (for instance, SkyHook Wireless) but they required a paid license.<\/p>\n
Paranoïa<\/h4>\n
In keeping with the theme, you can drop a file called unauthorizedApps<\/code> in \/Library\/Documents\/WebServer\/clbl\/<\/code> and start your webserver. You can then edit the file at will to deny a particular app the use of CoreLocation.<\/p>\n
Contents<\/h4>\n
\n
\n
PhoneLocation\/PhoneLocation.xcodeproj<\/dt>\n
Sample application that demonstrates using CoreLocation on the iPhone\/iPod Touch.
\nBuild and go, it will find your current location (which, in the Simulator, is 1, Infinite Loop, Cupertino, CA). Press the “Show Me” button to go to these coordinates in Google Maps.<\/dd>\n
DesktopLocation\/DesktopLocation.xcodeproj<\/dt>\n
Sample application that demonstrates using CoreLocation on the Desktop. It uses the Desktop CoreLocation framework in exactly the same manner as PhoneLocation, but the results are pulled from my version of the framework.
\nPress the “Show Me” button to go to these coordinates in Google Maps.<\/dd>\n
