The warning is because your key is unival, which is a unichar, which is
a C type, not an object pointer. An NSNumber should work as a key since
NSMutableDictionary defines setObject:forKey: as taking an id for the
key (although I've never used anything other than NSStrings). I'm not
sure what you're trying to accomplish here - I didn't see any previous
thread in which you may have discussed that. If you can clarify what
you're trying to put in the dictionary, perhaps I can suggest an
alternate method.

I am trying to make sense of a basic problem I have with dictionaries.
I am trying to assign a set of unicode values to array, and then store
those values in a dictionary. The problem is that I get a warning.
Here is the code.
// SET UP FULL DICTIONARY OF BOPOMOFO CHARS
unichar bpmfArray[37];
NSString *bpmf[37];
NSMutableDictionary *fullBpmfDic = [NSMutableDictionary dictionary];
int i;
unichar unival = 0x3105; // the first character in bopomofo series
for (i = 0; i < 37; i++) {
bpmfArray[i] = unival;
bpmf[i] = [NSString stringWithCharacters: &bpmfArray[i] length:1];
[fullBpmfDic setObject: bpmf[i] forKey: unival];
NSLog(@"%C %C", bpmfArray[i], bpmf[i]);
unival++;
}
The warning I get is as follows:
main.m:39: warning: passing arg 2 of `setObject:forKey:' makes pointer
from integer without a cast
It seems that I am supposed to use an object for the key, not just the
dictionary object. But what type should I use? I got a complaint for
NSNumber, and somehow 0x3105 does not strike me to be a "string."
More importantly, there must be a better way to go about this. Is
there a simple way to put all Unicode values of a certain type into a
dictionary? People have suggested I look into "localizer" but I am not
"translating strings" but rather want to import large swathes of
characters and associated data into files. Now, the data will probably
be a flat comma-delimited file, so I am wondering how I can iimport
that kind of thing into a dictionary. The dictionaryWithContentsOfFile
seems to presume XML-formatted material, which I don't have. Any
suggestions?
