Synopsis

function ok (value) {}
function fail (error) {}

var prefs = plugins.appPreferences;

// cordova interface

// store key => value pair
prefs.store (ok, fail, 'key', 'value');

// store key => value pair in dict (see notes)
prefs.store (ok, fail, 'dict', 'key', 'value');

// fetch value by key (value will be delivered through "ok" callback)
prefs.fetch (ok, fail, 'key');

// fetch value by key from dict (see notes)
prefs.fetch (ok, fail, 'dict', 'key');

// remove value by key
prefs.remove (ok, fail, 'key');

// show application preferences
prefs.show (ok, fail);

// instead of cordova interface you can use promise interface
// you'll receive promise when you won't pass function reference
// as first and second parameter

// fetch the value for a key using promise
prefs.fetch ('key').then (ok, fail);

// support for iOS suites (untested)
var suitePrefs = prefs.iosSuite ("suiteName");
suitePrefs.fetch (...);
suitePrefs.store (...);

Platforms

1. Native execution on iOS / OSX using NSUserDefaults
2. Native execution on Android using android.content.SharedPreferences
3. Native execution on Windows Phone using IsolatedStorageSettings.ApplicationSettings
4. Native execution on Windows 8 using IsolatedStorageSettings.ApplicationSettings
5. Execution on BlackBerry10 fallback using localStorage

Notes

1. iOS, OSX, Android and Windows Phone basic values (string, number, boolean) are stored using typed fields.
2. Complex values, such as arrays and objects, are always stored using JSON notation.
3. Dictionaries are supported on iOS and Windows 8 only, so on other platforms instead of using the real dictionary a composite key will be written like <dict>.<key>
4. On iOS/OSX dictionaries just a key, so appPrefs.store ('dict', 'key', value) and appPrefs.store ('dict', {'key': value}) have same meaning (but different result).

Tests

Tests are available in src/test.js. After installing plugin you can add test code from this file and then launch testPlugin() function.

iOS, Android, BlackBerry 10 and Windows Phone 8 tests pass ok at the moment.

Show Preference pane

If you have generated preferences, you can programmatically show preference pane (Android and iOS at this time). On Android your application show native interface for preferences, on iOS you'll be switched to the Settings.app with application preferences opened for you. Either way, you must listen for Cordova resume event to perform preferences synchronization.

Preferences interface generator

Preferences generator installed along with plugin and run every time when you prepare you cordova app.

After plugin installation you can find file app-settings.json within your app folder.

If you want to disable this functionality, please remove app-settings.json.

iOS note: if you have Settings.bundle from external source or previous version of generator cordova prepare will fail. Current version of preference generator trying not to rewrite existing Settings.bundle if it is not generated by plugin. It is save to remove Settings.bundle if it came from previous version of plugin.
