Initializing with NSNumber

Having this declared:

NSNumber *mike;

Does this..

mike = [[NSNumber alloc] initWithInt: 23];

do the same thing(alloc and init) as this?

mike = @23;

Hello Waldo,

You are correct in that setting the mike variable to a number literal, such as @23 in this case, will call [[NSNumber alloc] initWithInt:23]. You can read more about Objective-C literals here.

I hope this helps.
