TTTAttributedLabel 富文本小记

- (void)setupTipsLabel:(TTTAttributedLabel *)label {

    UIColor *red = [UIColor mainColor];
    UIColor *gray = [UIColor colorWithHexString:@"0x888888"];
    NSString *text = @"注：门店客服、预约电话、救援电话可支持填写最多5个电话，多个电话用英文 "," 隔开";
    
    NSMutableAttributedString *detailStr = [[NSMutableAttributedString alloc] initWithString:text];
    [detailStr addAttribute:(NSString *)NSFontAttributeName value:[UIFont systemFontOfSize:14] range:NSMakeRange(0, text.length)];
    [detailStr addAttribute:(NSString *)NSForegroundColorAttributeName value:red range:NSMakeRange(0, 2)];
    [detailStr addAttribute:(NSString *)NSForegroundColorAttributeName value:gray range:NSMakeRange(2, text.length-2)];
    
    //设置缩进、行距
    NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
    style.lineSpacing = 10;//行距
    [detailStr addAttribute:NSParagraphStyleAttributeName value:style range:NSMakeRange(0, text.length)];
    
    [label setAttributedText:detailStr];
    label.lineBreakMode   = NSLineBreakByWordWrapping;
}

设置普通的行间距

- (void)setLabel:(TTTAttributedLabel *)label WithText:(NSString *)text {
    label.textColor = [UIColor colorWithHexString:@"0x888888"];
    label.numberOfLines   = 0;
    label.font            = [UIFont systemFontOfSize:14];
    label.lineBreakMode   = NSLineBreakByWordWrapping;
    label.lineSpacing = 15;
    // 这里真是坑,文字非得设置在最后才有效果，用了下系统的，不会有这种现象
    label.text            = text;
}
