錯(cuò)誤提示:

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) ("<NSAutoresizingMaskLayoutConstraint:0x7ffd30d86570 h=--& v=--& H:[UIView:0x7ffd30f33d50(640)]>","<NSLayoutConstraint:0x7ffd33065d20 H:[UIImageView:0x7ffd30f341c0]-(0)-| (Names: '|':UIView:0x7ffd30f34030 )>","<NSLayoutConstraint:0x7ffd30eaa760 H:|-(0)-[UIImageView:0x7ffd30f341c0] (Names: '|':UIView:0x7ffd30f34030 )>","<NSLayoutConstraint:0x7ffd330bf740 UIView:0x7ffd30f33d50.width == 2*UIImageView:0x7ffd30f341c0.width>","<NSLayoutConstraint:0x7ffd30d944d0 'UIView-Encapsulated-Layout-Width' H:[UIView:0x7ffd30f34030(375)]>" )Will attempt to recover by breaking constraint <NSLayoutConstraint:0x7ffd33065d20 H:[UIImageView:0x7ffd30f341c0]-(0)-| (Names: '|':UIView:0x7ffd30f34030 )>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.

?解決辦法:

出錯(cuò)的View .?translatesAutoresizingMaskIntoConstraints = NO ;即可解決

無(wú)意之中發(fā)現(xiàn)只要設(shè)置xib 中的size 為任意的iphone 尺寸也能解決上面的問題, 不能死inferred!!!
