次の関数を使用して、preferences.plist ファイルのすべてのキーと値を取得しています。/private/var/preferences/SystemConfiguration/preferences.plist

- (void)FindKeysAndValuesInPlist:(id)object forKeyNamed:(NSString *)keyName{
if ([object isKindOfClass:[NSDictionary class]])
{
      NSLog(@"%@",keyName);
    [object enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL *stop) {
        [self FindKeysAndValuesInPlist:value forKeyNamed:key];
    }];

}
else if ([object isKindOfClass:[NSArray class]])
{
    [object enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
        [self FindKeysAndValuesInPlist:obj forKeyNamed:nil];
    }];
}
else
{

    NSLog(@"%@.%@", keyName, object);
}   
}

Preferences.plist の内容の例:

{
CurrentSet = "/Sets/3B9E7BEB-5558-4497-803B-21B03E6A46C0";
NetworkServices =     {
    "014226AB-75B7-41CF-9B96-48E82FD6A395" =         {
        Interface =             {
            DeviceName = ip4;
            Hardware = "com.apple.CommCenter";
            Type = "com.apple.CommCenter";
            UserDefinedName = "com.apple.CommCenter (ip4)";
        };
        PrimaryRank = Never;
        UserDefinedName = "com.apple.CommCenter (ip4)";
        "com.apple.CommCenter" =             {
            AllowNetworkAccess = 0;
            Available = 1;
            Version = 11;
        };
    };
    "1C01B561-1A55-4E3B-82FC-CDFF5024F0D2" =         {
        Interface =             {
            DeviceName = ip1;
            Hardware = "com.apple.CommCenter";
            Type = "com.apple.CommCenter";
            UserDefinedName = "com.apple.CommCenter (ip1)";
        };
        UserDefinedName = "com.apple.CommCenter (ip1)";
        "com.apple.CommCenter" =             {
            AllowNetworkAccess = 1;
            Available = 1;
            SettingsHaveBeenAlteredByPreferences = 1;
            Setup =                 {
                apn = "";
                password = "";
                signature = <7ecb277c ad546563 3ac057fb db40aeaa 939f8c0e e7ae68c2 6e0ff602 77d3868d 18a63059 6c83f66d 46b8af57 d1bf83d0 2655ced6 57d773f4 5c7e733e 923aaa07 39165357 a4ecf270 130276f0 59c7470e 0b61a631 dff04fd1 0bc80cb4 a0dc0a03 96a8ebf0 74c24cdb 84c38239 9f6f7f05 ee032982 8ed1b72d b531405b 09e35f5b>;
                "type-mask" = 0;
                username = "";
            };
            Version = 11;
        };
    };

問題は、この種の出力形式を作成しようとしていることです: MAINKEY.SUBKEY.VALUE

例えば：

NetworkServices =     {
"014226AB-75B7-41CF-9B96-48E82FD6A395" =         {
    Interface =             {
        DeviceName = ip4;
        Hardware = "com.apple.CommCenter";
        Type = "com.apple.CommCenter";
        UserDefinedName = "com.apple.CommCenter (ip4)";
    };

次のようになります: NetworkServices.014226AB-75B7-41CF-9B96-48E82FD6A395.Interface.Hardware.ip4

ディクショナリ内のキーを反復処理します。キーの値が別のディクショナリの場合、キーをスタックにプッシュし、ディクショナリの値を再帰します。値が文字列または数値の場合、スタック内のキーを連結し、キーのパスと値を出力します。

コード：

+ (void)printDict:(NSDictionary *)dict keyStack:(NSArray *)keys
{
    if (keys == nil) {
        keys = [NSArray array];
    }

    for (id key in dict) {
        id value = dict[key];
        if ([value respondsToSelector:@selector(objectForKey:)]) {
            [self printDict:value keyStack:[keys arrayByAddingObject:key]];
        } else {
            NSLog(@"%@ = %@", [[keys arrayByAddingObject:key] componentsJoinedByString:@"."], value);
        }
    }
}
