声明

@property（readonly，copy）NSArray *textLists
@property（readonly，copy）NSArray *textBlocks

但是，看起来没有办法在iOS中访问它们而不进行内省，因为它们的声明不包括在UIKit中。

if ([paragraph respondsToSelector:@selector(textLists)])
  NSArray* lists = [paragraph performSelector:@selector(textLists)];

if let textLists = paragraphStyle.value(forKey: "textLists") as? NSArray {
  if let item = textLists.firstObject as? NSObject {
    print(item.description)
  }
}

实际上textLists属性在iOS上也可用。我不知道他们什么时候改变了它，但这是真的。https://developer.apple.com/documentation/uikit/nsparagraphstyle/1534193-textlists
现在你可以访问paragraphStyle.textLists来检查给定的NSAttributedString是否包含列表，你可以使用如下代码：

let attributedString = NSAttributedString(...) // get your attributed string

attributedString.enumerateAttribute(.paragraphStyle, in: NSRange(location: 0, length: length)) { value, range, _ in
  guard let paragraphStyle = value as? NSParagraphStyle else { return } // safe check
  if !paragraphStyle.textLists.isEmpty {
    // you got your list item
  }
}
