How to concatenate two strings on iPhone?

Question

How to connect string \"Hello\" and string \"World\" to \"HelloWorld\"? Looks like \"+\" doesn\'t work.

Answer 1

If you have two literal strings, you can simply code:

NSString * myString = @"Hello" @"World";

This is a useful technique to break up long literal strings within your code.

However, this will not work with string variables, where you'd want to use stringWithFormat: or stringByAppendingString:, as mentioned in the other responses.
