Objective-C Cocoa应用程序中的正则表达式

问题描述

初始Googling表示在Objective-C Cocoa应用程序中没有内置方法来执行正则表达式。

这四个问题：

$ b

这是真的吗？

好的，那么是否有一个很好的开源库？

解决方案

p>我注意到，从iOS 4.0苹果提供了。此外，从10.7开始，该类可用。

Initial Googling indicates that there's no built-in way to do regular expressions in an Objective-C Cocoa application.

So four questions:

1. Is that really true?

2. Are you kidding me?

3. Ok, then is there a nice open-source library you recommend?

4. What are ways to get close enough without importing a library, perhaps with the NSScanner class?

解决方案

I noticed that as of iOS 4.0 Apple provides a NSRegularExpression class. Additionally, as of 10.7, the class is available under OS X.
