Hello @Hakob Hovhannisyan ,
You can use UIDocumentInteractionController in Xamarin.iOS, please refer to the following code:
partial void ClicktoOpenInOtherAPP(UIButton sender)// a button action, click to present menu
{
string filename = NSBundle.MainBundle.PathForResource("test","png");// test.png is added in my project, its build action is BundleResource
UIDocumentInteractionController documentInteractionController = UIDocumentInteractionController.FromUrl(new NSUrl(filename, false));//you can replace this file by your other file path
documentInteractionController.PresentOpenInMenu(this.View.Bounds, this.View, true);// present
}
Best Regards,
Wenyan Zhang
