Hi!
Like so many other apps I have "Please be so kind to rate this app on the App Store"-button that the user can press.
This used to work: http://stackoverflow.com/questions/3124080/app-store-link-for-rate-review-this-app
Basically you just used UIApplication.SharedApplicationOpenUrl(url), where url is "itms-apps://blah/?id=APP_ID", and it would magically move the user to the app store where he/she could review the app.
I just tried this on an ipad 4 with the latest ios 7 beta installed, and it doesn't seem to work for our app. It does switch to the App Store, but it just sits there on a blank screen. Google turns up nothing, so is this intended behavior because it's running a beta(?), or has something changed? This might seem like not such a big deal, but the customer won't be a happy camper if iOS 7 is released and this feature suddenly break in his app :(
