Martin,
are you saying that "is not sure that if I do not change mTextMutableString,
and I call archivedDataWithRootObject several times, e.g. with one second
interval, the stringData could be different? I hope no.
I need to compare the data saved on the disk with the current
mTextMutableString. Do you know any better way?
Regards
Leonardo
