title: xcode app: safari won't go to app store link
body: <p>I put a link on a button in an iPhone app (xcode 4.2). The link does open a safari window successfully to other websites, but not to the iTunes Preview pages to specific apps. This problem occurs if the link is entered directly in the code. It also occurs on an indirect link to the app store page--i.e. a page with a working link to an iTunes app page gets there fine from Safari on the mac itself, but not when the page loads up on the iPhone simulator and the same link is clicked. 
  Any ideas?</p>
