Remove Characters and Everything After from String

Question

I am aware of replacing Strings of a String, but that only works if I know exactly what I want to remove.

If I have a String like the following:

\"hi-there-t

Answer 1

Look up pattern-matching, aka regular expressions.

Oh, wow, TIL there's no built-in way to do regular expressions in an Objective-C Cocoa? according to Regular expressions in an Objective-C Cocoa application

Anyway, there are libs mentioned in that question.

Answer 2

It can be done without REGEX like this:

NSString *string = @"hi-there-this-is-a-test&feature=hi-there";
    NSRange range = [string rangeOfString:@"&feature"];
    NSString *shortString = [string substringToIndex:range.location];
