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-this-is-a-test&feature=hi-there"

How do I remove '&feature' and everything that comes after that?

Any help would be greatly appreciated. Thanks in advance!

EDIT: If absolutely necessary to use REGEX, could someone show me how to use it? I am aware it is 10.7 onwards but I'm fine with that. Even better, an example of String trimming or using the NSScanner?

Thanks again everyone.

EDIT: The solution posted below is the correct one, but resulted in a crash for me. This is how I solved the problem:

NSString *newString = [[oldString componentsSeparatedByString: @"&feature="] objectAtIndex:0];

Answer 1

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];
