Masonry布局遇到的问题

2017-11-07 11:35:11.615 xxxxxxxxxx[20905:10828825] 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.

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.

约束设置有问题的时候报这个提示,同时设置了高度和上下边距或者同时设置了宽度和左右边距
