How to get a single character from an NSString

Question

This is what I'm using

[[remaining_string substringFromIndex:k] substringToIndex:1]

Is there a better way?

Answer 1

See characterAtIndex

NSString *myString = @"Hello, World";
unichar myChar = [myString characterAtIndex:k];

Note that this returns a unichar. You can use substringWithRange (see Henrik's answer) if you want a NSString.

Answer 2

And if you want a NSString this should work:

string2 = [string1 substringWithRange: NSMakeRange (k, 1)];
