Q:

If I buy an SSL Certificate, is this trusted in Apple without installing cert file in iOS?

I created an app for iOS for a company and I want to distribute this app ad hoc over the air.
In iOS 7 and greater, I need an https site to install this app.
I created my own certificate locally and I must install my cert file via email or a direct link on iPhone to Trust this certificate and then I can install my app.
I want to know: if I buy an SSL certificate from legal seller like godaddy or geocerts and set it to my own website, do I need install a cert file on the iPhone or not?
My company's site is offline and not connected to internet.

A:

Purchasing an SSL certificate will not require any further configuration on the device, regardless of whether this is from a 'standard' Certificate Authority.
If the certificate is purchased from a standard Certificate Authority, this provides the additional benefit of verifying the company being represented by the domain, but this is tangental to the actual HTTPS requirement by Ad-Hoc distribution.
