Description

What is the best way of vertically centralising the text of each collection view cell?

Here are my settings

`settings.style.buttonBarItemLeftRightMargin = 20 settings.style.buttonBarItemsShouldFillAvailableWidth = false settings.style.buttonBarItemFont = .systemFont(ofSize: 13, weight: 0.1) settings.style.buttonBarItemTitleColor = UIColor(red:255/255.0, green:255/255.0, blue:255/255.0, alpha:0.8)

    settings.style.buttonBarBackgroundColor = UIColor(red:255/255.0, green:255/255, blue:255/255.0, alpha:1.0)
    settings.style.buttonBarItemBackgroundColor = UIColor(red:255/255.0, green:255/255.0, blue:255/255.0, alpha:1.0)
    settings.style.selectedBarBackgroundColor = UIColor(red:32/255.0, green:163/255.0, blue:213/255.0, alpha:1.0)
    settings.style.selectedBarHeight = 2
    
    settings.style.buttonBarMinimumLineSpacing = 0
    settings.style.buttonBarLeftContentInset = 20
    settings.style.buttonBarRightContentInset = 20
    changeCurrentIndexProgressive = { [weak self] (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in
        guard changeCurrentIndex == true else { return }
        oldCell?.label.textColor = self?.nonSelectedColor
        newCell?.label.textColor = self?.selectedColor
        oldCell?.label.font = self?.nonSelectedFont
        newCell?.label.font = self?.selectedFont
    }`

Here is a screenshot, i want to make the gap between the text and the indicator smaller

Research direction
The issue is from 2017 and asks how to vertically center text in ButtonBarViewCell. Since it's old, check if the library has been updated or if there are newer versions. Look at the source code of ButtonBarViewCell to see how the label is positioned. Consider using Auto Layout or adjusting the label's content mode. The screenshot shows a gap between text and the indicator; reducing that gap may require modifying the cell's layout margins or constraints.
