title: Positioning objects relative to an ADBannerView
body: <p>I've been trying to wrap my head around the coordinates of an iAd banner view, which apparently goes by its own laws. I have a banner view at the bottom of the screen, and I define it likewise:</p>
  
  <pre><code>    adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
      CGRect adFrame = adView.frame;
      adFrame.origin.y = self.scene.view.frame.size.height - adView.frame.size.height;
      adView.frame = adFrame;
      [self.view addSubview:adView];
  </code></pre>
  
  <p>(this is inside of a sprite kit scene) So now, I want to position an object/node relative to this banner view. My first instinct to place this object higher than the banner by 5 was to say</p>
  
  <pre><code>node.position = CGPointMake(CGRectGetMidX(self.frame), adView.frame.size.height + 5);
  </code></pre>
  
  <p>However, this didn't give me any promising results so I decided to hardcode it and it turned out that I was able to get what I wanted if I set the y-value at around 64ish. I tested this value on an iPhone 6, which gave me what I wanted, but then when I tried it on the iPhone 5, it disappeared under the banner view. If the height of the iPhone adBannerView is 50 regardless of the model, this seems to be very contradictory. </p>
  
  <p>Any help will be appreciated, thanks!</p>
