Answer 1

Using collectionViewFlowLayout.sectionInset or collectionView:layout:insetForSectionAtIndex: are correct.

However, if your collectionView has multiple sections and you want to add margin to the whole collectionView, I recommend to use the scrollView contentInset :

UIEdgeInsets collectionViewInsets = UIEdgeInsetsMake(50.0, 0.0, 30.0, 0.0);
self.collectionView.contentInset = collectionViewInsets;
self.collectionView.scrollIndicatorInsets = UIEdgeInsetsMake(collectionViewInsets.top, 0, collectionViewInsets.bottom, 0);
