CGFloat margin = 5.0;
UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];
layout.itemSize = CGSizeMake(([UIScreen mainScreen].bounds.size.width - margin)/ 2, ([UIScreen mainScreen].bounds.size.width - margin)/ 2);
layout.minimumLineSpacing = margin;
layout.minimumInteritemSpacing = margin;

UICollectionView *collectionView = [[UICollectionView alloc] initWithFrame:[UIScreen mainScreen].bounds collectionViewLayout:layout];

margin, .
