Issue Description

Hi;

I have following code for my UICollectionView:

 //////////////////////// Item Recommendations Collection View in Second Container
[self.itemRecommendationsCollectionView remakeConstraints:^(MASConstraintMaker *make) {
    make.height.equalTo(@750);
 
    make.left.equalTo(self.itemRecommendationsContainerView.left).with.offset(@45);
    make.right.equalTo(self.itemRecommendationsContainerView.right).with.offset(@-45);
    make.bottom.equalTo(self.itemRecommendationsContainerView.bottom).with.offset(@-150);
    make.top.equalTo(self.itemRecommendationsTitleLabel.bottom);
}];

It is working fine. But I don't want to give constant height to my collection view.

If I change 750 to something else, it doesnt work. Height become 0.

What should I do for that?
