Objective C parse hex string to integer

I need the integer value of a NSString representing hex number. For example how do I get the int value (10) of the NSString @”A”?

Answer 1

{
  int value;
  [[NSScanner scannerWithString @"A"] scanHexInt: &value];
  // use value here
}

That would be the simplest code. The method scanHexInt returns a Bool indicating success which you’d want to handle.
