If you want to enforce singleton-ness, perhaps returning a replacement object from the designated initializer is a better idea. (Or perhaps not - there may be reasons not to do that which aren't obvious to me right now.)

The downside is that you'd have to release the current object before returning the new one. E.g.:


-(id) init
{
	if( gSharedObject )
		[self autorelease];
	else
	{
		self = [super init];
		gSharedObject = self;
	}

	return gSharedObject;
}
