also,
NSEnumerator *keyE = [[super tagDict] keyEnumerator]; //HERE
it is not a good strategy to use NSEnumerator at this point
what if super does not respond at all ?? ..... to avoid crash & infinite loop
you needs to specify 'forward messaging' ( another instance object that will
respond to tadDict ), so your code will be weird again with if ( if ( if (
NSEnumerator will be better to count the number of 'plist' file exist in a
bundle to prepare the quantity of dictionnary.
