Try this out, declare these variables

  NSInteger insets_Top=5;
  NSInteger insets_Bottom=5;
  NSInteger insets_Left=5;
  NSInteger insets_Right=5; 

and add these methods

 - (CGSize)collectionView:(UICollectionView *)collectionView layout:   (UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:   (NSIndexPath *)indexPath
{
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    CGFloat screenWidth = screenRect.size.width;
    CGSize img_size=CGSizeMake(screenWidth/num_items-   (insets_Right+insets_Left), screenWidth/num_items);
    return img_size;
}

  - (UIEdgeInsets)collectionView:
 (UICollectionView *)collectionView layout:  (UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:  (NSInteger)section
   {
      return    UIEdgeInsetsMake(insets_Top,insets_Left,insets_Bottom,insets_Right);
   }

Here num_items=7 as in your case you want number of cells in a row to be 7
