Question

In my current iPhone project, I have a created a dictionary that groups the sub dictionaries by the first letter of the “Name” key. NSLog returns the following. I would like to create an identical dictionary that only shows the “Name” key under each initial letter key. What is the best way for making a copy of some of the items in the sub dictionaries? The ObjectForKey methods will select only the items for the initial letter (ex: “B” or “C”). Please let me know if I didn’t explain this clearly enough.
Thanks!

sectionedDictionaryByFirstLetter:{
B =     (
            {
        Name = "B...A Name Starting with B";
        Image = "ImageName1.png";
        Text = "Some Text";
     }
 );
C =     (
            {
        Name = "C...A Name Starting with C";
        Image = "ImageName2.png";
        Text = "Some Text";
     }
 );
N =     (
            {
        Name = "N...A Name Starting with N";
        Image = "ImageName3.png";
        Text = "Some Text";

     },
            {
        Name = "N...A Name Starting with N";
        Image = "ImageName4.png";
        Text = "Some Text";

     },
            {
        Name = "N...A Name Starting with N";
        Image = "ImageName5.png";
        Text = "Some Text";

     }
   );
}

The final result I’m looking for is:

sectionedDictionaryByFirstLetter:{
B =     (
            {
        Name = "B...A Name Starting with B";
     }
 );
C =     (
            {
        Name = "C...A Name Starting with C";
     }
 );
N =     (
            {
        Name = "N...A Name Starting with N";
     },
            {
        Name = "N...A Name Starting with N";
     },
            {
        Name = "N...A Name Starting with N";
     }
   );
}

NSMutableDictionary* newDict = [NSMutableDictionary dictionary];
for (NSString* key in sectionedDictionaryByFirstLetter) {
    NSMutableArray* newList = [NSMutableArray array];
    [newDict setObject:newList forKey:key];
    for (NSDictionary* entry in [sectionedDictionaryByFirstLetter objectForKey:key]) {
        NSString* name = [entry objectForKey:@"Name"];
        [newList addObject:[NSDictionray dictionaryWithObject:name forKey:@"Name"]];
    }
}
