Creating Multiple Keys in array for plist

I'm trying to enable image document types to an app using objc. I have root access to the plist I need to write to. Just wrapping my head around how many keys, dictionaries, & arrays needed to code this has been frustrating me for over an hour. I can't get it right.

If I'm correct I'll need to create a NSMutableArray in a NSDictionary in another NSMutableArray?

I'm using NSMutableDictionary to write to the plist as below:

NSMutableDictionary *data; 
    if ([fileManager fileExistsAtPath: path]) { 
        data = [[NSMutableDictionary alloc] initWithContentsOfFile: path]; 
    } else {
        //no plist
    }

This is what I need to add to the plist:

<key>CFBundleDocumentTypes</key>
  <array>
    <dict>
      <key>CFBundleTypeName</key>
      <string>Images</string>
      <key>LSHandlerRank</key>
      <string>Alternate</string>
      <key>LSItemContentTypes</key>
      <array>
          <string>public.image</string>
      </array>
    </dict>
  </array>

Could someone point me in the right direction?

PList is the file representation of NSMutableDictionary :

You can use the following :

  NSMutableDictionary *data;
    if ([fileManager fileExistsAtPath: path]) {
        data = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
    } else {
        NSMutableArray *array = [[NSMutableArray alloc] init];


        NSDictionary *dict = [[NSMutableDictionary alloc] init];

        NSString *images = @"Images";
        [dict setValue:images forKey:@"CFBundleTypeName"];

        NSString *Alternate = @"Alternate";
        [dict setValue:images forKey:@"LSHandlerRank"];

        NSMutableArray *LSItemContentTypes = [[NSMutableArray alloc] init];
        NSString *publicImage = @"public.image";
        [LSItemContentTypes addObject:publicImage];

        [dict setValue:LSItemContentTypes forKey:@"LSItemContentTypes"];


        [data setObject:array forKey:@"CFBundleDocumentTypes"];

    }
