This code worked fine on iOS 12 and under and the issue occurs when running iOS 13. The goal is to remove the line height spacing to 0 so my labels have a reduced amount of space in between text. I have two labels inside a collection view cell and when I scroll the cells off the screen and then scroll back down the label text is now "cut off". This was not the case as I mentioned in previous versions of iOS. Any help fixing this would be amazing. Thanks ahead of time.
This is my code:
extension: UILabel {
func addLineSpacing(spacing: CGFloat) {
guard let text = text else { return }
let originalText = NSMutableAttributedString(string: text)
let style = NSMutableParagraphStyle()
let lineHeight = font.pointSize - font.ascender + font.capHeight
let offset = font.capHeight - font.ascender
let range = NSRange(location: 0, length: text.count)
style.maximumLineHeight = lineHeight
style.minimumLineHeight = lineHeight
style.alignment = .center
originalText.addAttribute(.paragraphStyle, value: style, range: range)
originalText.addAttribute(.baselineOffset, value: offset, range: range)
attributedText = originalText
}
}
This is how the UILabel text looks like before scrolling:
This is how it looks after scrolling. Notice how the text seems to be shifted up and cut off
