How can I select a string from the beginning until a specified character?
NSRange rangeOfDash = [someString rangeOfString:@"-"];
substring = (rangeOfDash.location != NSNotFound) ? [someString substringToIndex:rangeOfDash.location] : nil;
This sets the substring
to nil
if there's no dash in the someString
.

How can I select a string from the beginning until a specified character?
For example, in the following a news headline...
someString = @"Los Angeles, California - Apple announces something, stock prices change."
How do I select just
Los Angeles, California -
into a separate string? (I want to base my selection on everything before the-
("dash") character.EDIT:
Say my headline looks like this:
someString = @"Los Angeles, California - Apple announces something - stock prices change."
How do I prevent my location string from looking like this:
Los Angeles, California - Apple announces something
?Edit:
My mistake, I was removing the first dash and then reprising the string. My mistake the posted answer works.

Moshe over 13 yearsWhat would rangeOfDash be based on someString after parsing the whole thing?

Moshe over 13 yearsI only want the first dash, not subsequent dashes. see my edit.
