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

NSString *string = [NSString stringWithFormat:@"%@%@", @"Hello", @"World"];
NSLog(@"%@", string);

That should do the trick, although I am sure there is a better way to do this, just out of memory. I also must say this is untested so forgive me. Best thing is to find the stringWithFormat documentation for NSString.
