You shouldn't have to worry about cleaning it up afterwards, you should
return an autoreleased object. For example:
- (pref *)preferencesController
{

preferencesController = [[pref alloc] init];

return [preferencesController autorelease];
}
Whatever object requests it must keep it around by retaining it.
