Easy NSString substring

Sadly, creating a simple substring in Objective-C isn't quite as obvious as in other languages. Here's a basic method to grab a substring of a given string before a defined character, in my case the ":" character:

NSRange end = [_contentsOfElement rangeOfString:@":"];

[myVar setName:[_contentsOfElement substringWithRange:NSMakeRange(0, end.location)]];

If you wanted grab a string between two characters, you could do:

NSRange start = [_contentsOfElement rangeOfString:@"|"];

NSRange end = [_contentsOfElement rangeOfString:@":"];

[myVar setName:[_contentsOfElement substringWithRange:NSMakeRange(start.location, end.location)]];
