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?
