NSDray from NSDictionary - Simple Initialization Syntax

I'm starting Objective-C (from Python)
I need to create and initialize a simple dictionary.
In Python, I'm used to:

arr = [
    {'fieldX': value1, 'fieldY': value2},
    {'fieldX': value3, 'fieldY': value3},
]

Here is what I do in Objective-C

NSArray *arr = [NSArray arrayWithObjects:
    [NSDictionary dictionaryWithObjectsAndKeys:
        value1, @"fieldX", value2, @"fieldY"
      , nil]
  , [NSDictionary dictionaryWithObjectsAndKeys:
        value3, @"fieldX", value4, @"fieldY"
      , nil]
  , nil
];

Is there an easier way to initialize this array of dictionaries?

since ios6 you can use literals

NSArray *arr = @[
                 @{@"fieldX": value1, @"fieldY": value2},
                 @{@"fieldX": value3, @"fieldY": value3}
                ];
