How to get a single NSString character from an NSString

I want to get a character from somewhere inside an NSString. I want the result to be an NSString.

This is the code I use to get a single character at index it:

[[s substringToIndex:i] substringToIndex:1]


Is there a better way to do it?

Answer

This will also retrieve a character at index i as an NSString, and you're only using an NSRange struct rather than an extra NSString.

NSString * newString = [s substringWithRange:NSMakeRange(i, 1)];
