Adding the Plugin to your project

Using this plugin requires a PhoneGap project for iOS: Get Started Guide.

To install the plugin, move diagnostic.js to your project's www folder and include a reference to it in your html file after cordova.js:

  <script type="text/javascript" charset="utf-8" src="cordova-X.X.X.js"></script>
  <script type="text/javascript" charset="utf-8" src="diagnostic.js"></script>

Move Diagnostic.h and Diagnostic.m files into Plugins folder.

And edit Cordova.plist creating a new entry in the Plugins section as follows:

     - Key:    Diagnostic
     - Type:   String
     - Value:  Diagnostic

Using the plugin

The plugin creates the object:

 window.plugins.diagnostic

To use, call one of the following, available methods:

isLocationEnabled:

/**
 * Checks if location is enabled (Device setting for location and authorization).
 *
 * @param successCallback	The callback which will be called when diagnostic of location is successful.
 * 							This callback function have a boolean param with the diagnostic result.
 * @param errorCallback		The callback which will be called when diagnostic of location encounters an error.
 * 							This callback function have a string param with the error.
 */
isLocationEnabled()

Usage:

   window.plugins.diagnostic.isLocationEnabled(locationEnabledSuccessCallback, locationEnabledErrorCallback);

   function locationEnabledSuccessCallback(result) {
      if (result)
         alert("Location ON");
      else
         alert("Location OFF");
   }

   function locationEnabledErrorCallback(error) {
      console.log(error);
   }

isLocationEnabledSetting:

/**
 * Checks device settings for location.
 *
 * @param successCallback	The callback which will be called when diagnostic of location is successful.
 * 							This callback function have a boolean param with the diagnostic result.
 * @param errorCallback		The callback which will be called when diagnostic of location encounters an error.

isLocationEnabledSetting()

Usage:

   window.plugins.diagnostic.isLocationEnabledSetting(locationEnabledSettingSuccessCallback, locationEnabledSettingErrorCallback);

   function locationEnabledSettingSuccessCallback(result) {
      if (result)
         alert("Location ON");
      else
         alert("Location OFF");
   }

   function locationEnabledSettingErrorCallback(error) {
      console.log(error);

         alert("Authorized to use location");
      else
         alert("Not authorized to use location");

Usage:

   window.plugins.diagnostic.isWifiEnabled(wifiEnabledSuccessCallback, wifiEnabledErrorCallback);

   function wifiEnabledSuccessCallback(result) {
	   if (result)
	      alert("Wi-Fi ON");
