the view's position. This allows the auto layout system to track the frames of views whose
layout is controlled manually (through -setFrame:, for example).
When you elect to position the view using auto layout by adding your own constraints,

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
