Sharing Content

The data transfer manager allows sharing content from your application using the OS sharing dialog. To check whether sharing is supported at runtime, use IsSupported() method:

if (DataTransferManager.IsSupported())
{
    // Sharing is supported    
}

Currently, the following types of content can be shared:

Type of content Android iOS macOS WASM Tizen
Text
Uri
File

To set up the DataTransferManager use the following snippet:

var dataTransferManager = DataTransferManager.GetForCurrentView();
dataTransferManager.DataRequested += DataRequested;
dataTransferManager.ShowShareUI();

Make sure to unregister the DataRequested event after finished sharing.

In the DataRequested method, you can set the data to be shared in the DataRequestedEventArgs:

private void DataRequested(DataTransferManager sender, DataRequestedEventArgs args)
{        
    args.Request.Data.Properties.Title = "Sharing dialog title";
    args.Request.Data.Properties.Description = "Description";

    args.Request.Data.SetText("Text to share");
    args.Request.Data.SetWebLink(new Uri("https://platform.uno/"));
}

If you need to prepare the data asynchronously, you can use a deferral:

private async void DataRequested(DataTransferManager sender, DataRequestedEventArgs args)
{        
    var deferral = args.Request.GetDeferral();

    args.Request.Data.Properties.Title = "Sharing dialog title";
    args.Request.Data.Properties.Description = "Description";

    var text = await SomeOperationAsync();
    args.Request.Data.SetText(text);
    
    deferral.Complete();
}

To control the location where the sharing dialog shows up on iOS and macOS, use the ShowShareUI(ShareUIOptions) overload. ShareUIOptions.SelectionRect denotes the area the user is interacting with and will be taken into account by the OS. On iOS, you can also specify ShareUIOptions.Theme to make the dialog dark/light based on your app's preference. On other Uno targets, these properties have no effect.

On Tizen, the "http://tizen.org/privilege/appmanager.launch privilege must be declared in the application manifest to allow sharing.
