Finding various substrings in NSString

Question

I have an NSString and am attempting to find the first location of either of three strings @"aaa" and @"bbb" and @"ccc".

range = [text rangeOfString:@"aaa" options:NSCaseInsensitiveSearch range:NSMakeRange(rangeStart, rangeLength)];

Is there any simple way to add a logical operator (or) to the rangeOfString: method? I tried rangeOfString:(@"aaa" || @"bbb" || @"ccc") but it threw an exception. Or is there a simple workaround. Thanks.

Use Regular Expression

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"(aaa|bbb|ccc)" options:0 error:NULL];
NSTextCheckingResult *match = [regex firstMatchInString:text options:0 range:NSMakeRange(0, [text length])];

Hope this helps...
