Displaying json Response in UITableViewCell?

This is my json response from webservice,

ChangedOptions =     (
            {
        Descriptions =             (
            "some text"
        );
        Invoice = 0;
        MSRP = 0;
        OptionCode = "some text";
        OptionGroup = "some text";
        OptionSection = Packages;
        State = Selected;
    },
            {
        Descriptions =             (
            "some text"
        );
        Invoice = 50;
        MSRP = 50;
        OptionCode = "some text";
        OptionGroup = "some text";
        OptionSection = Packages;
        State = Unselected;
    },
            {
        Descriptions =             (
                  "some text"
        );
        Invoice = 0;
        MSRP = 0;
        OptionCode = 28F;
        OptionGroup = "some text";
        OptionSection = Packages;
        State = Required;
    },
            {
        Descriptions =             (
                 "some text"
        );
        Invoice = 0;
        MSRP = 0;
        OptionCode = 27F;
        OptionGroup = "CPOS PKG";
        OptionSection =PowerTrain;
        State = Excluded;
    },

}

i want too fetch the particular array index using the OptionSection

ex: in this response i have to display the Description,Invoice,MSRP,OptionCode,OptionGroup i.e, cor开发者_开发百科responding to the "Packages" if OptionSection = "Packages" is more than one count i have to display all those things in UITableView

please give any suggestion for that
