- [LayoutConstraints] Unable to simultaneously satisfy constraints.
- 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.
- (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

- 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.
