title: NSUserDefaults not cleared after app uninstall on simulator
body: <p>this may sound real NOOB! I want to check if it's the second time the user enters my application, so to keep the run count I'm using <code>NSUserDefaults</code>. I have implemented the following code in my <code>rootViewController</code>'s <code>viewDidLoad</code> method:</p>
  
  <pre><code>    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
  
      NSLog(@"hello %ld", (long)[userDefaults integerForKey:@"runCount"]);
  
      if ([userDefaults integerForKey:@"runCount"] != 1) {
          //not the 2nd run
          [userDefaults setInteger:1 forKey:@"runCount"];
          NSLog(@"not 2nd run");
      } else {
          //second run or more
          NSLog(@"2nd run");
      }
  
      [userDefaults synchronize];
  </code></pre>
  
  <p>everything works fine, but the problem is that when I uninstall(delete and re-install) the application according to <a href="https://stackoverflow.com/questions/9163798/is-data-stored-in-nsuserdefaults-persists-through-application-updates-and-on-app">here</a> and <a href="https://stackoverflow.com/questions/7520800/are-values-stored-in-nsuserdefaults-removed-when-the-app-that-put-them-there-is">here</a> the data should be cleared, but it is not and after re-installing the app previous data is still showing up.
  I'm running my app on iOS simulator using xCode6-beta and targeting the application on iOS 8</p>
