I am creating an app that talks to a postgresql
database. i have a few tables in my interface and I
have been trying to decide how to store the data in
the database. I have also been toying with just
passing the array and storing that. It would be easier
to handle. I set up the class to conform to NSCoder
and it appears that I can create a proper NSData
object form the array.
So how to store the data in the database? I notice
that the description is a representation of the data
in hex... I have been thinking of just storing this
hex in the database. But how can I recreate the array
from the hex?
Am I barking up the wrong tree? should I not use the
hex and store the binary? If I do, I have to escape it
and I don't want to do that.
So I guess the question is, "How can I convert the hex
representation of the NSData object back to an NSData
object"?
Any ideas would be welcome..
Ted
