Using Autoreleased Constructors

From: namedConstructor.m

4 + (id)object
5 {
6   return [[[self alloc] init] autorelease];
7 }

I said in the last section that objects created with +alloc have a retain count of one. In fact, all objects are created with a retain count of one, but objects created with a named constructor, such as +stringWithFormat: or +array, are also autoreleased.
