2014-09-21 11:21:04.807 ALtest[42953:7217373] 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) 
	
	/// As it says, we need to read the constraints one by one and see if there's one that says something we don't want.

)

The problem is that every button is constrained to be width 20 and every space is constrained to be 65. Nothing can flex at all.

So it has to be 65+20+65+20+65+20+65 == 320 points wide. That's no good, because the superview has to be 375 points wide.

If you wanted the width of the buttons to get bigger as the screen gets bigger, then you want to delete the constraint that says that button1 must be exactly 20 points wide.
