设置label行数为0

  [label 
setNumberOfLines:0
];

准备工作

    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:string];
    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];

调整行间距

[paragraphStyle 
setLineSpacing
:lineSpace];

    设置

    [attributedString addAttribute:NSFontAttributeName
                       value:label.font
                       range:NSMakeRange(0, string.length)];
    
    [attributedString addAttribute:NSParagraphStyleAttributeName
                             value:paragraphStyle
                             range:NSMakeRange(0, [string length])];
    
    label.attributedText = attributedString;

    获取label bounds

    CGSize size = [label.attributedText boundingRectWithSize:CGSizeMake(label.frame.size.width, 1000) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading context:nil].size;
    label.frame = CGRectMake(label.frame.origin.x, label.frame.origin.y, size.width, size.height);
    [label sizeToFit];
