Are the (( an artifact of the way you've presented the data in your
email, or are they part of what toString outputs?
If the former, I don't know what you've done wrong, but if it's the
latter, it would appear there is only one key in the dictionary, and
that is the array ("idNum", "uF1", "archiveTo", "uF2", "uF3",
"histLimit") and there is one value in the dictionary, and that is the
array ("numOnly", "Field 1", "", "Field 2", "Field 3", "8").
Creating the NSDictionary can be done like this:
NSDictionary dict = new NSDictionary(new Object[] {
"idNum", "uF1", "archiveTo", "uF2", "uF3", "histLimit"
}, new Object[] {
"numOnly", "Field 1", "", "Field 2", "Field 3", "8"
});
try this and see if dict.valueForKey("uF1") still gives null.
HTH,
