Creating a Resource to Display a UI View
When the initialize method is called, if the certificate provider needs to get input from the user, such as username and password or server URL, then the certificate provider should implement the logic to display the UI for acquiring the input from the user.
In the X509FileCertificateProvider sample, a dialog is used to allow the user to enter the file certificate path and password.
For the iOS client, the storyboard must be added into the main application's resource bundle.
