Objective-C 正则表达式类别

这个项目是一系列对 NSRegularExpression 和 NSString 进行分类的 Objective-C，使得使用更加简单和紧凑。

//Using NSRegularExpression
NSString* string = @"I have 2 dogs.";
NSRegularExpression *regex = [NSRegularExpression
    regularExpressionWithPattern:@"\\d+"
    options:NSRegularExpressionCaseInsensitive
    error:&error];

NSTextCheckingResult *match = [regex firstMatchInString:string
     options:0
     range:NSMakeRange(0, [string length])];

BOOL isMatch = match != nil;

// Using this library
BOOL isMatch = [@"I have 2 dogs." isMatch:RX(@"\\d+")];
