title: How to handle iPhone 4s, 5 and 6 screen size, and make all the contents look the same across al the devices
body: <p>I am using Xcode 6.1 and in one of the views I have, contains many labels. However, these labels look different in each different devices. Although I have add constraints to all the labels, but still facing the same issue. </p>
  
  <p>How can I get the same view layout across all devices? 
  How can I make the width and height for each label is flexible, depends on the screen size?
  Do I need to design different xib for each device? </p>
