Search through NSString using Regular Expression
cocoa, nsstring, objective-c
Solution
You need to use `NSRegularExpression` class.
Example inspired in the documentation:
NSString *yourString = @"";
NSError *error = NULL;
NSRegularExpression *regex = [NSRegularExpression
regularExpressionWithPattern:@"(NS|UI)+(\\w+)"
options:NSRegularExpressionCaseInsensitive
error:&error];
[regex enumerateMatchesInString:yourString options:0 range:NSMakeRange(0, [yourString length]) usingBlock:^(NSTextCheckingResult *match, NSMatchingFlags flags, BOOL *stop){
// your code to handle matches here
}];
Problem
How might I go about searching/enumerating through an `NSString` using a regular expression? A regular expression such as: `/(NS|UI)+(\w+)/g`.
