If I would want to allocate a class which allocates a single subclass
instead, to
hide the class implementation details
would this be the correct way of doing it?
The following code would be in the BaseClass
+ (id)allocWithZone:(NSZone*)aZone
{
if ([[self class] isEqualTo:[BaseClass class]])
{
return [[SubClass alloc] init];
} else {
return [super allocWithZone: aZone];
}
}
