Titanium.App.Properties
Extends Titanium.ModuleTitanium.Proxy
Extended by Titanium.App.iOS.UserDefaults
The App Properties module is used for storing application-related data in property/value pairs that persist beyond application sessions and device power cycles.
App Properties in the tiapp.xml file
App properties defined in the tiapp.xml file may be accessed using these APIs. An app
property is defined inside the root-level <ti:app> element with the <property> element.
Use the name attribute to define your property name and place the value inline with the
<property> element. For example, to define an app property called foo with the value 42:
<?xml version="1.0" encoding="UTF-8"?>
<ti:app xmlns:ti="http://ti.titaniumsdk.com">
<property name="foo" type="string">42</property>
</ti:app>
Then, you can retrieve the property during runtime with the following API call:
const foo = Ti.App.Properties.getString('foo');
Any application properties defined in the tiapp.xml file are stored in the
device's secure storage, making them read-only. Additionally, external access to these
properties is now restricted. Other iOS applications cannot access these properties and
native Android modules must use the Titanium module API TiApplication.getAppProperties()
method to access these properties.
If you need to change the values during runtime, initially create the property with these APIs
rather than defining them in the tiapp.xml file.
Important: Using this API in the Apple ecosystem requires the NSPrivacyAccessedAPICategoryUserDefaults
property set in the privacy manifest that was introduced in iOS 17. You can learn more about it here.
Examples
Store a property
Store a string property.
Ti.App.Properties.setString('givenName', 'Paul');
Ti.API.info('The value of the givenName property is: ' + Ti.App.Properties.getString('givenName'));
Enumerate over saved properties
Output all saved properties to the console.
var props = Ti.App.Properties.listProperties();
for (var i = 0, ilen = props.length; i < ilen; i++){
var value = Ti.App.Properties.getString(props[i]);
Ti.API.info(props[i] + ' = ' + value);
}

Events 1
Fired when a property is changed.

The event is also fired when the application changes a property directly using one of the
Ti.App.iOS.UserDefaults or Ti.App.Properties methods.
