title: Autolayout constraints warning "Will attempt to recover by breaking constraint"
body: <p>I am setting some specifics constraints for iPhone 4 when the app is ran on this device. Everything look great in terms of alignment and everything.</p>
  
  <p>But, I am getting an error for all my constraints that is trying to recover them by breaking the constraints.</p>
  
  <p>This method gets call in my viewDidLoad when it detects if its an iPhone 4</p>

      Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it.

  Break on objc_exception_throw to catch this in the debugger.
  The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in &lt;UIKit/UIView.h&gt; may also be helpful.
