title: How to center align a UILabel on top of an UIImageView
body: <p>I have an UIImageView that has a UILabel on top of it. This UILabel has a text that shows a number to the user of how many people like his content ( kinda like the Facebook likes or comments ),
  Both the UIImageView and the UILabel are small in size so the UI needs to be just perfect. Right now if the UILabel shows a 2 digits number it still shows up aligned properly but when I get into the 3 digits it kinds skews off, how can I make sure that I can always align it to the UIImageView via code?</p>
