Unable to simultaneously satisfy constraints 约束冲突问题

对scrollerview的约束出现了

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 的错误

只需要在scrollerview中设置优先级区别就可以了
