Objective-C 解析器扑克手牌历史

Question

我正在为 iOS 构建一些需要解析扑克手牌历史的软件。由于我对解析了解不多，我希望有人能给我指出正确的方向，给我一些教程，...

我已经开始将扑克手分成几行，然后我开始用字符串函数处理每一行。但现在我已经看到有可用的解析工具，我可以为其编写 BNF 语法。所以如果我想实现性能，这可能是正确的方法，对吧？但是，我对 BNF 语法以及如何使用它们一无所知，...任何人都可以指点我一些初学者教程吗？

哦，扑克手牌历史看起来像这样:

Answer 1

BNF 将是执行此操作的理想方法...但是，如果您的时间有限并且不想学习太多，我可以建议一个快速而肮脏的解决方案。使用正则表达式并根据匹配项进行切换。
