I have a plist file that I am loading into an NSDictionary *setDictionary that contains a set of fields, pictureDesc1, pictureDesc2, etc.

Once the NSDictionary is loaded, I can retrieve a value using

[setDictionary objectForKey:@"pictureDesc1"];

But I cannot do a loop like this:

for (int i=1; i<=numberOfPictures; i++) {
    NSString *keyName = [NSString stringWithFormat:@"pictureDesc%d",i];
    NSString *description = [NSString stringWithFormat:@"%@", [setDictionary objectForKey:keyName]];
}

Is there a different way to dynamically call keys from within an NSDictionary?
