What is the actual purpose of registering a class in objective c?

[self.photoCollectionview registerClass:[PhotoCollectionViewCell class] forCellWithReuseIdentifier:@"cellIdentifier"];

Looking at this line of code, I'm curious about why we employ the method of registerClass. What does it actually do and why do we need it?
