About coreLocationExample

Learning Objectives

This Example demonstrates using the native CoreLocation Apple SDK to understand your device's general cardinal direction.

After studying this example, you'll understand how to grab the CoreLocation information from your device, and use it to rotate an image in your application for immediate feedback within the interface.

In the code, pay attention to:

• The initialization of and use of the ofxiOSCoreLocation object.
• startHeading() and startLocation() methods of the ofxiOSCoreLocation object are called in the setup(), telling native Apple SDKs to begin sending you the device's details.
• getTrueHeading(), getLatitude(), and getLongitude() methods of the ofxiOSCoreLocation bring back fun and useful geo-spatial data, used in both the update() and draw() events.

Expected Behavior

When launching this app, you should see a screen with:

• A compass-like visual interface that rotates with your movement throughout space.

Instructions for use:

• Move around, point your device at your nearest landmark, and note its cardinal direction.
