How to display the last char of the NSString *

Question

I want to ask a question about the NSString * in objective C. I have an string read from somewhere and I would like to get the last char of that NSString object? I used to try the objectAtIndex, but I don't know what to get the index. What should I type? Thank you very much.

Answer 1

unichar lastChar = [yourString characterAtIndex:[yourString length] - 1]; 

or if you want it as an NSString:

NSString *lastChar = [yourString substringFromIndex:[yourString length] - 1];
