我正在尝试设置NSAttributedString. 问题是我不能为文本设置一个小的行距。我可以为前导设置很大的值，例如 25 或更多，但忽略较小的值。我正在尝试设置kCTParagraphStyleSpecifierMinimumLineHeightor kCTParagraphStyleSpecifierMinimumLineSpacing，但它不起作用。

这是我的代码，任何帮助表示赞赏。

CGFloat leading = 50.0;
CGFloat minMineHeight = 1;
CTTextAlignment alignment = kCTCenterTextAlignment;

const CTParagraphStyleSetting styleSettings[] = {

    {kCTParagraphStyleSpecifierMinimumLineSpacing, sizeof(CGFloat), &minMineHeight},
    {kCTParagraphStyleSpecifierMinimumLineHeight, sizeof(CGFloat), &minMineHeight},
    {kCTParagraphStyleSpecifierLineSpacing, sizeof(CGFloat), &leading},
    {kCTParagraphStyleSpecifierParagraphSpacing, sizeof(CGFloat), &leading},
    {kCTParagraphStyleSpecifierAlignment, sizeof(CTTextAlignment), &alignment}
};

CTParagraphStyleRef style = CTParagraphStyleCreate((const CTParagraphStyleSetting*) &styleSettings, 5);
[mutableAttributedString addAttribute:(NSString*)kCTParagraphStyleAttributeName value:(__bridge id)style range:NSMakeRange(0, [mutableAttributedString length])];
CFRelease(style);

return mutableAttributedString;

您还需要设置最大行距。
