How to cut a string at a specific point?

Question

So, I have a vast quantity of NSStrings and my problem is I need to cut them into smaller strings at a specific point. This may sound complicated but what I need basically is this:

NSString *test =" blah blah blah - goo goo goo.";
NSString *str1 = "blah blah blah ";
NSString *str2 = "goo goo goo";

How do I code for when there's a hyphen for the string to just cut off there. Is there a way to do this? I found ways to cut of the string after a certain amount of letters but I need it at the hyphen every time.

NSArray *arr = [string componentsSeparatedByString:@"-"];

should do the trick.

You could do this many ways. Two answers above show a few approaches. Many Objective-C solutions will include NSRange usage. You could also do more flexible things with NSScanner or NSRegularExpression. There is not going to be one right answer.

NSString *cutString = [text substringFromIndex:3];
cutString = [text substringToIndex:5];
cutString = [text substringWithRange:NSMakeRange(3, 5)];
