ios - 多行中行与行之间的核心文本空间

Question

UITextView和Core Text绘制

为什么多行之间的间距不同？

Answer 1

简单

CGFloat lineHeight = 17.0;

CTParagraphStyleSetting settings[2] = {
        { kCTParagraphStyleSpecifierMinimumLineHeight, sizeof(lineHeight), &lineHeight },
        { kCTParagraphStyleSpecifierMaximumLineHeight, sizeof(lineHeight), &lineHeight }
}
