使用DTCoreText显示HTML代码时出错

Question

我使用DTCoreText的DTHTMLAttributedStringBuilder在UITableViewCell中显示HTML代码。但它有一个错误。 这是我的代码：

NSDictionary *builderOptions = @{DTDefaultFontFamily: @"Helvetica"};
DTHTMLAttributedStringBuilder *stringBuilder = [[DTHTMLAttributedStringBuilder alloc] initWithHTML:[word[@"name"] dataUsingEncoding:NSUTF8StringEncoding] options:builderOptions documentAttributes:nil];
NSAttributedString *stringAttri = [stringBuilder generatedAttributedString];

cell.textLabel.attributedText = stringAttri;

这是错误：

    [__NSCFType lineBreakMode]: unrecognized selector sent to instance 0x7f7f7bd1ba60
