to the property minimumLineSpacing of UICollectionViewFlowLayout the apple's document said:

For a vertically scrolling grid, this value represents the minimum spacing between successive rows. For a horizontally scrolling grid, this value represents the minimum spacing between successive columns

i test it and the part of code like this:

self.layout1 = [[UICollectionViewFlowLayout alloc] init];
self.layout1.scrollDirection = UICollectionViewScrollDirectionHorizontal;
self.layout1.minimumLineSpacing = 100.0f;

the result is that the minimumLineSpacing is still added between the rows but not the columns,but i have found that if this delegate method: -(CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPathreturn a fixed value it is ok, the minimumLineSpacing will be added between the columns ,but not if it return a dynamic value,what is the issue?
