Question

我正在为iOS构建一些需要解析扑克手牌历史的软件。由于我不太了解解析，我希望有人能指出我正确的方向，指点我一些教程，......

我已经开始分手了扑克牌，然后我开始用字符串函数处理每一行。但是现在我已经看到有可用的解析工具，我可以编写BNF语法。如果我想要达到性能，这可能是正确的方法，对吧？但是，我对BNF语法一无所知，以及如何使用它们，......任何能指导我为初学者提供教程的人都会这样做吗？

Ow，扑克手牌的历史看起来像这样：

Answer 1

BNF将是实现这一目标的理想方式......但是如果你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。
