JBNSLayoutConstraint Helper Categories
Apple introduced iOS support for Auto Layout in iOS 6.0, and while it wasn’t love at first sight, I eventually came to appreciate the power and flexibility of NSLayoutConstraint. I’m one of those developers who doesn’t use Interface Builder, nibs, or Storyboards. I’m not against any of those technologies…it’s just that I like to build my interfaces in code. For me, Auto Layout has made it much easier to create Universal Apps that intelligently resize to take advantage of multiple display types.
