how to modify the buttonBarView selectedBar width, I don't want him so wide

Answer 1

This is how I was able to achieve the resizing of the tabs. Since ButtonBarPagerTabStripViewController inherits from UICollectionView you can just override the sizeForItemAtIndexPath function and return the preferred width and hieght.

Swift 3

override func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: IndexPath) -> CGSize {
    return CGSize(width: "preferred witdth", height: collectionView.frame.size.height)
}
