Вы можете использовать collectionView:layout:insetForSectionAtIndex:
метод для вашего UICollectionView
или установить sectionInset
свойство UICollectionViewFlowLayout
объекта, прикрепленного к вашему UICollectionView
:
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section{
return UIEdgeInsetsMake(top, left, bottom, right);
}
или
UICollectionViewFlowLayout *aFlowLayout = [[UICollectionViewFlowLayout alloc] init];
[aFlowLayout setSectionInset:UIEdgeInsetsMake(top, left, bottom, right)];
Обновлено для Swift 5
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
return UIEdgeInsets(top: 25, left: 15, bottom: 0, right: 5)
}
