iOS崩溃报告"意外启动状态"异常？

我找到了几个崩溃报告的原因unexpected start state.我的代码看起来像这样:

NSRange range = [content rangeOfString:@"<html>"];

if (range.location != NSNotFound) {
    NSString *htmlStr = [content substringFromIndex:range.location];

    NSAttributedString *attStr = [[NSAttributedString alloc] initWithData:[htmlStr dataUsingEncoding:NSUnicodeStringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType} documentAttributes:nil error:nil];

    return attStr.string;
}

如果不在主线程上,NSAttributedString initWithData和NSHTMLTextDocumentType会崩溃

调用

NSAttributedString * as = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)} documentAttributes:nil error:nil];

NSAttributedString冻结UITableView

使用NSAttributedString滚动时应用程序确实冻结(当我使用NSString它工作正常),所以有我的方法:

- (void)setSubtitleForCell:(TTTableViewCell *)cell item:(TTPhotoPost *)item
{
    NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:
                                            [item.caption dataUsingEncoding:NSUnicodeStringEncoding]
                                                                            options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType }
                                                                 documentAttributes:nil
                                                                              error:nil];

    [cell.descriptionLabel setAttributedText:attributedString];
}

那里有什么错误吗？或某种方式使att.string更快？
