singleton in objective c

Question

I saw a singleton example on objective-c book. However, I don\'t know if there is difference of meaning of \'singleton\' definition between objective-c and other langs. Can this

Answer 1

There is no language support for singletons, but you can do it by hand. Look at the singleton example here. It doesn't look like it is thread-safe, though. I would allocate the object in +initialize instead of +sharedManager.
