object-c plist help

good day.  i need some help with reading from a plist.  i am an objective-c noob and would appreciate any help and code examples.  i don't believe i am far off.

i have a root.plist with two text field items.

my code to read from the list:

 -(void)readConfigurationItemsFromSettingsBundle{
        NSString *settingsBundle = [[NSBundle mainBundle] pathForResource:@"Settings" ofType:@"bundle"];
        if(!settingsBundle) {
            NSLog(@"Could not find Settings.bundle");
            return;
        }
        
        NSDictionary *settings = [NSDictionary dictionaryWithContentsOfFile:[settingsBundle stringByAppendingPathComponent:@"Root.plist"]];
        NSArray *preferences = [settings objectForKey:@"PreferenceSpecifiers"];
   
        for (NSString *str in preferences)
          NSLog(@"--%@", str);
  }

Select allOpen in new window

here are my results:

 --{
    Key = "server_ip";
    Title = "server ip address";
    Type = PSTextFieldSpecifier;
}
--{
    Key = "audio_number";
    Title = "audio notification #";
    Type = PSTextFieldSpecifier;
}

i'm looking for the actual values within each key, but i don't know how to go about it....

thank you.
