I’m trying to resize a UICollectionElementKindSectionHeader but a didn’t find any way.

Can anyone help me please?

You can use the UICollectionViewDataSource Protocol method:

- (UICollectionReusableView *)collectionView: (UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath  {

   // dequeue your resuable headerview and set your custom frame here...

   return headerView;
}

Also, if you are implementing the UICollectionViewDelegateFlowLayout Protocol, you can use the following method to adjust the size of section headers that are already dequeued:

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section {

   CGSize headerViewSize = CGSizeMake(300, 40);

   return headerViewSize;
}
