constraints is funny

if u use Masonry or updateConstraints to a UIView, may no reaction till u drag one constraints to it…

Becoz

1. storyboard default has constraints already (if u dun drag any) it just the current frame be the constraints (if u tick autolayout which is usually ticked)
2. when u drag the constraints, it override
3. when u code using Masonry or constrains programming, it override

But sometimes it will say broken, becoz the constraints jammed… so… one solution:

it will ignore all the storyboard constraints, so u can use the coding one now.
