Change Log - April 12, 2018

Features

• You can store/retrieve just about any type of object (thanks to Newtonsoft.Json)
• You can monitor for changes using the Changed event
• iCloud Settings Provider
• You can use roaming profiles which is useful for:
  • iOS app groups
  • iOS extensions
  • iWatch
  • Android Wear

To use, simply call:

var int1 = CrossSettings.Current.Get<int>("Key");
var int2 = CrossSettings.Current.Get<int?>("Key");

CrossSettings.Current.Set("Key", AnyObject); // converts to JSON
var obj = CrossSettings.Current.Get<AnyObject>("Key");

Strongly Typed Binding (works with all platforms - no fancy reflection that breaks on iOS)

var myInpcObj = CrossSettings.Current.Bind<MyInpcObject>(); // Your object must implement INotifyPropertyChanged
myInpcObj.SomeProperty = "Hi"; // everything is automatically synchronized to settings right here

//From your viewmodel
CrossSettings.Current.Bind(this);

// make sure to unbind when your model is done
CrossSettings.Current.UnBind(obj);

To supply your own implementation:

CrossSettings.Current = new YourImplementationInheritingISettings();

Monitor setting changes:

CrossSettings.Current.Changed += (sender, args) => {
    Console.WriteLine(args.Action);
    Console.WriteLine(args.Key);
    Console.WriteLine(args.Value);
};

Dependency Injection:

Autofac

    containerBuilder.Register(x => CrossSettings.Current).As<ISettings>().SingleInstance();
    
    OR for strongly typed

    containerBuilder.Register(_ => CrossSettings.Current.Bind<YouAppSettings>()).AsSelf().SingleInstance();
