SKStoreReviewController requestReview() may or may not present and alert? : <p>I'm taking a look at the new <code>requestReview()</code> API that uses <code>SKStoreReviewController</code>. The documents state:</p>

<p>"Although you should call this method when it makes sense in the user experience flow of your app, the actual display of a rating/review request view is governed by App Store policy. Because this method <strong><em>may or may not</em></strong> present an alert, it's not appropriate to call it in response to a button tap or other user action."</p>

<p>Does anyone have any experience using this API. What exactly are the factors that determine if the rating view is shown or not? I'm guessing it's not shown if called too frequently.. Anybody have any insight on this? Thanks!</p>
