How to use Share in Xamarin.iOS

Issue

I am following the documentation here:

https://docs.microsoft.com/en-us/xamarin/essentials/share?tabs=android

To implement the share functionality in my Xamarin.iOS app. My code:

byte[] pdf = await DownloadPdfFile();

var fn = "myfile.pdf";
var file = Path.Combine(FileSystem.CacheDirectory, fn);
await File.WriteAllBytesAsync(file, pdf);

await Share.RequestAsync(new ShareFileRequest
{
    Title = ViewModel.Parameter.Title,
    File = new ShareFile(file)
});

Nothing happens when I run this code.

Solution

I solved it. There is a bug when running on iPad as mentioned here and you can fix this by specifying the PresentationSourceBounds:

await Share.RequestAsync(new ShareFileRequest
{
    Title = "My title",
    File = new ShareFile(file),
    PresentationSourceBounds = new System.Drawing.Rectangle((int)View.Frame.Width, 0, (int)(View.Frame.Width), (int)(View.Frame.Height))
});
