title: UI scaling in different iPad versions and iPad models?
body: <p>I will launch my App for the first time targeting iPads (universal). My problem is I came across some inequalities in how the UI scales at different iOS-versions and iPad models. This is the list of different models form the iPad simulator I tested it against:</p>
  
  <p>iPad 2 7.0</p>
  
  <p>iPad 2 7.1</p>
  
  <p>iPad 2 8.1</p>
  
  <p>iPad Air 7.0</p>
  
  <p>iPad Air 7.1</p>
  
  <p>iPad Air 8.1 (scales perfectly)</p>
  
  <p>iPad Retina 7.0</p>
  
  <p>iPad Retina 7.1</p>
  
  <p>iPad Retina 8.1 (scales perfectly)</p>
  
  <p><em>Some examples and results can be seen in the Pictures below. The inequalities how the tabBar and UISlider scales in different iOS versions and models:</em></p>

  <p>My questions are. </p>
  
  <p><strong>1</strong>.How come my tabBar background picture is so messed up in example iPad 2 iOS 7.0 and not iPad Air 8.1 ? (Is it different dimensions I need to consider while using a background picture?)</p>
  
  <p><strong>2</strong>.Can I possibly target different models / versions of iPads and fix my UI like you do with macros for iPhone6 / iPhone6P ? And then how?</p>
  
  <p><strong>3</strong>.How come the interface tabBar background picture scales differently in <strong>iPad Air 7.0</strong> and <strong>iPad Air 7.1</strong>?. These are the same iPad models with the only inequalities in different iOS versions?</p>
  
  <p>All help is appreciated / Regards</p>
