Answer 1

Have you try this. Change your sizeForItemAtIndexPath function with my one.

- (CGSize)collectionView:(UICollectionView *)collectionView
          layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
    if (indexPath.row%3==0) {
        return CGSizeMake(self.collectionView.frame.size.width, 80);
    }
    CGFloat minSpace = 10; //Set this minSpace for space that you want between two cell
    return CGSizeMake((self.collectionView.frame.size.width - minSpace)/2, 80);
}

Also change your cellForItemAtIndexPath if condition with this if condition to return two different cell. If you have.

Hope this will help you.

Answer 2

Your target cell index order order are 0 , 1,2 , 3 , 4,5 6 , 7,8 9 ,...... Your order for identification is 0,3,6,9... code for size for item at indexpath should be

- (CGSize)collectionView:(UICollectionView *)collectionView
                  layout:(UICollectionViewLayout*)collectionViewLayout
  sizeForItemAtIndexPath:(NSIndexPath *)indexPath {


    NSUInteger pos = indexPath.row;
    if(pos%3==0)
    {
        return CGSizeMake(dynamicCollection.frame.size.width-10, 80);

    }
    else
    {
       return CGSizeMake(dynamicCollection.frame.size.width/2-10, 80);
    }

}

In your story board provide inset for sections 5,5,5,5 . Select the collectionview and in scale attribute.
