Customizing Apple Elements for Enterprise iOS Apps

Friday I spent time figuring out how to customize UIAlertView to allow altering the message text color and altering the background color of that text body. It was an interesting exercise to say the least. As a side note, when the messages gets large, Apple changes the UILabel to some type of internal custom UIWebView to allow scrolling.

Such a hack wouldn't be allowed in the App store I'm sure, but this is an enterprise distributed app that doesn't have to go through that process. I'm wondering how popular this tactic is in enterprise development. Can those with such exposure please comment.

Thank you for your insight.

P.S. For those wondering, yes, I placed in defensive coding in case Apple alters something that would break the subclass. I coded (and tested) it to gracefully downgrade to the normal UIAlertView expectations. I wish I was allowed to share the code as I think I did nice work on this.
