NSAttributedString 不显示段落缩进
NSAttributedString not showing paragraph indentation
我从 HTML 创建了一个 NSAttributedString，就像这样。
decodedString = [[NSAttributedString alloc] initWithData:[encodedString dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: [NSNumber numberWithInt:NSUTF8StringEncoding]} documentAttributes:nil error:nil];
当我在 UITextView 中显示字符串时，除了段落缩进外，一切都显示得很好。
正在转换为 NSAttributedString 的 HTML 是。

通过一些研究，我了解到 </p> 代码用于段落前后的 space 页边距。我猜 AttributedString 不是 "understanding" 这个或其他东西。
NSAttributedString应该理解</p>？
为什么会这样？
我该如何解决？
谢谢！
<p> 标签只是定义文本段落。如果您指的是首行缩进，它们不会格式化段落。
这是您的 HTML 的示例，请注意段落没有缩进。

尝试在每个段落前输入 \t，如果这是您要查找的内容。
