使用Masonry一不小心就会出现各种问题。
今天的问题大概是这样的：
Assertion failure in -[MASViewConstraint addConstraintWithLayoutAttribute:],
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Attributes should be chained before defining the constraint relation'
控制台截图：
错误原因：
_operationButton 是一个按钮，添加了如下约束
图中红色圈中的width应该修改成with。这里不是设置宽度，是给当前的约束添加附加条件（我这里是偏移量），应该用介词with，而不是width。
