NSMutableAttributedString上的iOS行间距属性

Question

我们如何在NSMutableAttributedString上设置行间距或行高.我试过了

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
[paragraphStyle setLineSpacing:150] ;
paragraphStyle.minimumLineHeight = 150;
[self addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, self.length)];

没有运气.

任何建议将不胜感激.

谢谢

你需要设置paragraphStyle.maximumLineHeight.

我希望它会有所帮助!
