NSTextField Line Spacing in Swift

Question

如何使用Swift或在Interface Builder中以编程方式设置多行NSTextField的行间距？

Answer 1

You can use NSAttributedString to modify this (Swift 4 example):

    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineSpacing = 10.0  // sets the space BETWEEN lines to 10 points
    paragraphStyle.maximumLineHeight = 12.0 // sets the MAXIMUM height of the lines to 12 points

    let text = "Your text"
    let attributes = [.paragraphStyle: paragraphStyle]
    textField.attributedStringValue = NSAttributedString(string: text, attributes: attributes)
