Issue Description

I got a problem!
I used an array that contains some views to make constraints (mas_distributeViewsAlongAxis).
When the device rotate, the subviews need to update constraints. But the subviews is add a new constraint, not update already exist constraint. I found the method
- (void)mas_distributeViewsAlongAxis:(MASAxisType)axisType withFixedSpacing:(CGFloat)fixedSpacing leadSpacing:(CGFloat)leadSpacing tailSpacing:(CGFloat)tailSpacing
or
- (void)mas_distributeViewsAlongAxis:(MASAxisType)axisType withFixedItemLength:(CGFloat)fixedItemLength leadSpacing:(CGFloat)leadSpacing tailSpacing:(CGFloat)tailSpacing
used
mas_makeConstraints
to add new constraints. For example, a view already set left = 10.0, and then add a new constraint set left = 15.0, the old left constraints i still exist.

How can i to resolve this problem, i tried to call the method
mas_updateConstraints
in
- (void)mas_distributeViewsAlongAxis:(MASAxisType)axisType withFixedSpacing:(CGFloat)fixedSpacing leadSpacing:(CGFloat)leadSpacing tailSpacing:(CGFloat)tailSpacing
and it resloved my problem, but i do not think it is a good method to resolve this problem. Please give me a help.
