title: disable UIAppearance-API happen on RemoteViewControllers
body: <p>So i am styling all my views using the apprearance api.
  F.e. i style my <code>UINavigationBar</code> using:</p>
  
  <pre><code>[[UINavigationBar appearance] setBackgroundImage:navigationBarBgImage forBarMetrics:UIBarMetricsDefault];
  </code></pre>
  
  <p>i want to use the advantage of the appearance api of styling all my <code>UINavigationBar</code>s in one single place (because i have multiple of them), so i don't want to do some subclassing only because of styling reasons. </p>
  
  <p>i also popup some <code>MFMessageComposeViewController</code>s and a <code>SLComposeViewController</code> to post to imessage or facebook.</p>
  
  <p>my problem here is, if i try to select albums on facebook or select contacts on imessage modalview, this happens:</p>

  <p>see the recursive description of the imessage modal view:</p>
  
  <pre><code>$0 = 0x1f1f1320 &lt;UIWindow: 0x1e5c8900; frame = (0 0; 320 568); layer = &lt;UIWindowLayer: 0x1e5c8a00&gt;&gt;
     | &lt;UILayoutContainerView: 0x1e592860; frame = (0 0; 320 568); autoresize = W+H; layer = &lt;CALayer: 0x1e592910&gt;&gt;
     |    | &lt;UINavigationTransitionView: 0x1f1c88a0; frame = (0 0; 320 568); clipsToBounds = YES; autoresize = W+H; layer = &lt;CALayer: 0x1f1c8960&gt;&gt;
     |    |    | &lt;UIViewControllerWrapperView: 0x1f1ee090; frame = (0 20; 320 548); autoresize = W+H; layer = &lt;CALayer: 0x1f2f9560&gt;&gt;
     |    |    |    | &lt;UIView: 0x1f2f3d20; frame = (0 0; 320 548); autoresize = W+H; layer = &lt;CALayer: 0x1f2f3d80&gt;&gt;
     |    |    |    |    | &lt;_UISizeTrackingView: 0x1f2effd0; frame = (0 0; 320 548); clipsToBounds = YES; autoresize = W+H; layer = &lt;CALayer: 0x1f2f00b0&gt;&gt;
     |    |    |    |    |    | &lt;_UIRemoteView: 0x1f2f01e0; frame = (0 0; 320 568); transform = [0.5, -0, 0, 0.5, -0, 0]; userInteractionEnabled = NO; layer = &lt;CALayerHost: 0x1f2f0330&gt;&gt;
  </code></pre>
  
  <p>any ideas whats the best to switch back there to default mode?</p>
