GitHub release (with filter) Nuget CI Release Notes


This plugin lets you use the BEMCheckBox in your Xamarin iOS applications. Below outlines how to get started with BEMCheckBox in Xamarin and some common uses. For a list of all the features of the please see the BEMCheckBox GitHub page.


XPlugins is a NuGet Package and can be installed using the dotnet command line:

dotnet add package SaturdayMP.XPlugins.iOS.BEMCheckBox

You can find other ways to install the latest stable version of the BEMCheckBox XPlugin via NuGet. You can find work in progress (WIP) and alpha builds on MyGet. If you have any trouble installing please let me know by opening an issue.


To create a BEMCheckBox call the constructor with a frame as shown below.

var checkbox = new SaturdayMP.XPlugins.iOS.BEMCheckBox(new CoreGraphics.CGRect(140, 40, 25, 25));

You can modify things such as making the checkbox square:

checkbox.BoxType = BEMBoxType.Square;

You can also change the animation type:

checkbox.OnAnimationType = BEMAnimationType.Fill;
checkbox.OffAnimationType = BEMAnimationType.Fill;

Yes you can set the on and off animation types to be different. You can set the color:

checkbox.OnFillColor = UIColor.Red;

To change if the checkbox is checked or not:

// Check to the checkbox.
checkbox.On = true;

// Uncheck the checkbox.
checkbox.On = false;

Finally to handle checkbox clicks setup an event:

private void CheckBoxClickedEvent(object sender, EventArgs eventArgs)
  var checkbox = sender as BEMCheckBox;
  if (checkbox == null)
  // Do what you need to do with the checkbox.

Then subscribe to it:

checkbox.AnimationDidStopFor += CheckBoxClickedEvent;

For a full list of settings such as animation type, colours, etc see the BEMCheckBox page.

You can also play with the BEMCheckBox settings in the Example Client. To run the Example Client open the source in Visual Studio 2017 and set the Example Client as the startup project. If the Example Client does not run please let me know.

The version of this BEMCheckBox plugin will match the BEMCheckBox major and minor version number but the patch number might differ.
