unable to simultaneously satisfy constraints. -凯发ag旗舰厅登录网址下载

开发版本  7.0 

@property(nonatomic) bool translatesautoresizingmaskintoconstraints ns_available_ios(6_0); // default yes

此属性 6.0 版本

错误提示:

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) ("","","","","" )will attempt to recover by breaking constraint make a symbolic breakpoint at uiviewalertforunsatisfiableconstraints to catch this in the debugger. the methods in the uiconstraintbasedlayoutdebugging category on uiview listed in may also be helpful.

 解决办法:

出错的view . translatesautoresizingmaskintoconstraints = no ;即可解决

无意之中发现只要设置xib 中的size 为任意的iphone 尺寸也能解决上面的问题, 不能死inferred!!!
