Unable to simultaneously satisfy constraints

2017-02-21 21:40:32.056084 sinaweibo[23285:492651] [LayoutConstraints] 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

<NSLayoutConstraint:0x60000028f820 sinaweibo.TGStatusPictureV:0x7faf8dc30a00.height == 140   (active)>

出现类似上面的错误时，查找最后一句的约束，在XIB 的自动布局约束中修改优先级，如下图
