Can an iphone app transparently connect to an https site, using a DER certificate shipped with the app?

I would like my app to connect to an https site, without开发者_如何学运维 user input required. So, I would like to send the app a certificate that the app will install in the keychain, and allow it to connect to the https site without the user getting involved.

How can I do this?

Thanks!

Applications are not able to install certificates to the keychain for security reasons.

Otherwise malicious programmers could install a certificate that authenticates phishing sites.
