RETRIEVING AN ARRAY ENTRY FROM AN ARRAY
-
From test plist file
_______________________________________________
<key>DeviceList</key>
<array>
<string>XSKey1</string>
<string>XSKey2</string>
<string>XSKey3</string>
</array>
_______________________________________________
Code
_______________________________________________
[objectPopUp removeAllItems];
NSArray *deviceArray;
deviceArray = [[NSUserDefaults standardUserDefaults]objectForKey:
@"DeviceList"];
[objectPopUp addItemsWithTitles:deviceArray];
_______________________________________________
While this code does work with the array "DeviceList" if it has strings
stored in it as listed.
The problem is that each entry in this array is an array with 3 entries and I
only wish to retrieve the first (0) entry from each array.
Here is the actual plist file content

I've tried "arrayForKey" but it doesn't populate the menu and
"stringArrayForKey" doesn't seem to work either so I'm assuming that I should be using
arrayForKey and then extracting the data I require from it, any ideas for a
solution???

Please avoid re-post and uppercase titles.
You have to use a NSEnumerator to scan your array. For example, and As
I remeber without testing :
-------------------
NSArray *deviceArray = [[NSUserDefaults standardUserDefaults]
objectForKey:@"DeviceList"];
NSEnumerator *e = [ deviceArray objectEnumerator ];
NSString *currentDevice;
[objectPopUp removeAllItems];
while (currentDevice = [ e nextObject ]) {
[objectPopUp addItemWithTitle:currentDevice];
}

For those that don't know, all caps have traditionally been used to
signify SHOUTING, within electronic communication, at least from the
early days of the Internet (long before the Web). It's just not polite
to SHOUT, unless there is a awfully good reason. Additionally, for some
of us (I happen to be in this group), for one reason or another, we have
a difficult time reading and/or stomaching all caps. (Personally, I
think one of the main sources for my aversion to all caps stems from my
old FORTRAN days working with IBM punch cards.)
Just a friendly note of netiquette.

Most people get the impression that you are shouting, when writing in
uppercase.
Another thing is that if the reader is using a flexible font, uppercase
letters are usually wider than lowercase letters, and the reader can
only see a part of the subject line.
Some time ago, someone posted a good "list etiquette" link.
Unfortunately I forgot the address, but found 2 that are quite short,
and mentions the basics...

If you want further reading, try Google "list etiquette". =)
Happy list-emailing!

I guess I have been under a rock too long. Southern New Mexico mountains are
somewhat remote.
Thanks for the info.

Ouch!!! I wonder how many of those *I* am guilty of! They're all good
points, though. The biggest problem that bugs me, though, are those who
immediately reply with "RTFM".
When someone asks a question that can be answered just by looking at
the method signature, that's one thing. But if someone actually posts a
request for clarification and has obviously read (but misunderstood)
the "$@#$#*@ manual", nobody benefits from a trite remark. Especially
if the remark is followed by "look at the archives." If nobody asks
those obvious questions and nobody answers them, they'll never end up
in the archives to begin with, right? ;-)
It's all about building a knowledge base. From the mundane to the
so-advanced-it-should-be-in-an-assembly-forum, it's all the same: If
you don't ask, you'll never know. Additionally, some concepts can be
understood when explained once. Others, however, require a few
explanations from a few different angles before they finally click in
some peoples' heads. I know that because I'm one of those people. ;-)
So, while I agree we should all follow etiquette AND NOT FRIGGIN
SHOUT AT ONE-ANOTHER, nor ask brain-dead questions, we should also add
as many good descriptions from as many angles as possible to the
archives. Or post a link to the best description so that when someone
searches for info under a particular keyword (right or wrong) they'll
always find a link to the appropriate information. That alone would cut
down on repetitive posts, no?
Just my 0.00794723 Euros. ;-)

Sure. But if they *are* already in the archives, there is no gain by
asking and answering the same questions over and over again.
So the point ist: Search the archives *first * and if that did not help
(because you either didn't find an answer or the solution didn't work
for you) *then* ask the list.
There's nothing wrong with asking if you couldn't work out something
despite looking at the archives and the documentation (even if the
answer is there). There *is* something wrong if you didn't even try ...
That's how I think about it anyway.
bye. Andreas.

Incidentally, the best bit of advice in that essay (in my opinion, of

This kind of thing comes up over and over again, on every developer
mailing list I've ever frequented. It's also very good advice for bug
reports, DTS incidents, and developer feedback messages.

A good idea is also to tell people that you tried, and, more
importantly, what you got. Mentioning the search terms you used could
also be useful, because while the pros may think of the right search
term naturally, it may just be that you picked an unlucky word to
google for.

What do you think?" ;-)
