NSString *HTMLString = [NSString stringWithFormat:@"<html><body>%@</body></html>", str ];
NSDictionary *options = @{NSDocumentTypeDocumentAttribute : NSHTMLTextDocumentType,

};
NSData *data = [HTMLString dataUsingEncoding:NSUTF8StringEncoding];
NSMutableAttributedString * attributedString = [[NSMutableAttributedString alloc] initWithData:data options:options documentAttributes:nil error:nil];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init]; // 调整行间距
paragraphStyle.lineSpacing = 8.0;
paragraphStyle.alignment = NSTextAlignmentJustified;
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, attributedString.length)];
[attributedString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:15] range:NSMakeRange(0, attributedString.length)];
UILabel *HTMLLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 100, [UIScreen mainScreen].bounds.size.width - 40, 0)];
HTMLLabel.backgroundColor = [UIColor cyanColor];
HTMLLabel.numberOfLines = 0;
HTMLLabel.attributedText = attributedString;
[HTMLLabel sizeToFit];
[self.view addSubview:HTMLLabel];
