UICollection View Flow Layout Vertical Align

Question

By default, when you are using the flow layout in a collection view, cells are centered vertically. Is there a way to change this alignment ?

Answer 1

@DongXu's answer is correct. However, I suggest to make those calculations in UICollectionViewFlowLayout's prepare() method. It will prevent multiple calculations on the same cell's attributes. Moreover, prepare() is better place to manage attributes cache.
