My first Apple App Store Rejection

So I'm making a game for the Apple iPhone. I've made a couple of apps in the store and haven't been rejected yet. Until of course, last night. I was trying to add a quick and dirty scoreboard system to my game and was using an undocumented API to add a textfield to UIAlertView.

I read everywhere that many apps use it and Apple was allowing it, so I tried. No one posted anything about being rejected because of it. It didn't work. Apple has automated systems that automatically reject an app using the private API's. These are the methods I used:

addTextFieldWithValue:label:
textFieldAtIndex:

So if you are planning on selling your app in the app store, don't use them. I ended up building my own modal score entry view and adding it over the cocos2d window.

Anyway, it turned out the rejection was a blessing because I found out that my anti-piracy code was broken and I did an about face on a previous decision. This gave me the opportunity to fix stuff before the initial launch.
