Collection View Cell Size 

Snippet for sizing the collectionViewCell depending on the screen size 

Given its original designed for 4.7" inches 

-(CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath{
    return CGSizeMake(<#currentWidthfor4.7inches#> *self.view.bounds.size.height/667.0, <#height#>*self.view.bounds.size.width/375.0);
}
