Checking for geolocation access


Applications that make use of a device's location data must be granted permission by the user. The user is prompted when an app attempts to access location data for the first time. Devices running iOS 4 or above will remember this choice, whereas older versions of iOS will request access each time the app is launched. In addition, access privileges can be changed at any time from the device's settings.

It is important that your app can detect the availability of geolocation data, and also respond to permission changes at runtime. Let us see how this is done.

Getting ready

An FLA has been provided as a starting point.

From the book's accompanying code bundle, open chapter9\recipe3\recipe.fla into Flash Professional.

A dynamic text field with an instance name of output has been added to the stage.

We will write an app that listens for the availability of the geolocation data and reports any changes to the output text field.

How to do it...
