PIN keyboard for Xamarin.Forms.

PIN keyboard for Xamarin.Forms

Usage

1. Add the following NuGet package: https://www.nuget.org/packages/FormsPinView/

   OR

   add FormsPinView.Core, FormsPinView.iOS, and FormsPinView.Droid to your solution.

2. Initialize iOS and Android renderers:

    // iOS:
    public override bool FinishedLaunching(UIApplication app, NSDictionary options)
    {
        ...
        global::Xamarin.Forms.Forms.Init();
        PinItemViewRenderer.Init();
    }
    
    // Android:
    protected override void OnCreate(Bundle bundle)
    {
        ...
        global::Xamarin.Forms.Forms.Init(this, bundle);
        PinItemViewRenderer.Init();
    }
   

3. Add PinView to your page:

    ...
    xmlns:local="clr-namespace:FormsPinView.Core;assembly=FormsPinView.Core"
    ...
        <local:PinView
            HorizontalOptions="CenterAndExpand"
            VerticalOptions="CenterAndExpand"
            TargetPinLength="4"
            Validator="{Binding ValidatorFunc}"
            Success="Handle_Success" />
   

4. PinView is MVVM-ready, so you can bind the following properties:

Property	Type	Description	Default	Required
Validator	Func<IList<char>, bool>	Function to check entered PIN	null	Yes
PinLength	int	The PIN length	4	No
SuccessCommand	ICommand	Invoked when the correct PIN is entered	null	No
ErrorCommand	ICommand	Invoked when an incorrect PIN is entered	null	No
ClearAfterSuccess	bool	Indicates whether the entered PIN should be cleaned or not after it was confirmed as correct	true	No
BorderColor	Color	View tint color.	Gray	No
Color	Color	View basic color.	Black	No
RippleColor	Color	View touch-effect color.	Gray	No
