Search through NSString using Regular Expression

How might I go about searching/enumerating through an

NSString
using a regular expression?

A regular expression such as:
/(NS|UI)+(\w+)/g
.

Answer

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
}];
