ios - JSON フィードからの辞書の NSMutableArray は、主要な iOS の新しいオブジェクトを挿入します

Question

JSON フィードから辞書の配列を受け取り、それを jsonArray と呼ばれる NSMutableArray に割り当てます。

jsonArray = [deserializedData objectForKey:@"reports"];

フィードは次のようになります。

reports =     (
            {
        address = "The street";
        email = "alex@blah.co.uk";
        "eng_id" = 1;
        "eng_name" = "Alex McPherson";
        "eng_thumb" = "http://someurl/image/1.png";
        form = Test;
        id = 59;
        lat = "51.1438330";
        live = 1;
        lng = "0.8693330";
        location = "17 Victoria Crescent, Ashford, TN23 7HL";
        name = "Alex McPherson";
        phone = 01233000000;
        rid = "A5C963-C95B-C3D639";
        title = "#A5C963-C95B-C3D639, Litter";
        tm = "2013-04-28 20:44:20";
        type = 5;
        "type-text" = "Litter";
    },
            {
        address = "The street";
        email = "alex@blah.co.uk";
        "eng_id" = 2;
        "eng_name" = "Rob Burt";
        "eng_thumb" = "http://someurl/image/1.png";
        form = Test;
        id = 122;
        lat = "51.1415000";
        live = 1;
        lng = "0.8715000";
        location = "38 Beaver Road, Ashford, TN23 7RP";
        name = Alex;
        phone = 01233000000;
        rid = "5A5C96-9072-6BAFA9";
        title = "#5A5C96-9072-6BAFA9, Litter";
        tm = "2013-04-28 20:35:56";
        type = 8;
        "type-text" = "Litter";
    };

私がやりたいことは、キーの新しい値をこのjsonArrayに挿入することです: distance = "0.16km" しかし、私の脳は今夜だけ働いていません....

したがって、新しい jsonArray は、上記のキー値が追加された次のようになります。

reports =     (
            {
        address = "The street";
        email = "alex@blah.co.uk";
        "eng_id" = 1;
        "eng_name" = "Alex McPherson";
        "eng_thumb" = "http://someurl/image/1.png";
        form = Test;
        id = 59;
        lat = "51.1438330";
        live = 1;
        lng = "0.8693330";
        distance = "0.16km";
        location = "17 Victoria Crescent, Ashford, TN23 7HL";
        name = "Alex McPherson";
        phone = 01233000000;
        rid = "A5C963-C95B-C3D639";
        title = "#A5C963-C95B-C3D639, Litter";
        tm = "2013-04-28 20:44:20";
        type = 5;
        "type-text" = "Litter";
    },
            {
        address = "The street";
        email = "alex@blah.co.uk";
        "eng_id" = 2;
        "eng_name" = "Rob Burt";
        "eng_thumb" = "http://someurl/image/1.png";
        form = Test;
        id = 122;
        lat = "51.1415000";
        live = 1;
        lng = "0.8715000";
        distance = "2.13km";
        location = "38 Beaver Road, Ashford, TN23 7RP";
        name = Alex;
        phone = 01233000000;
        rid = "5A5C96-9072-6BAFA9";
        title = "#5A5C96-9072-6BAFA9, Litter";
        tm = "2013-04-28 20:35:56";
        type = 8;
        "type-text" = "Litter";
    };

基本的に、フィードから経度と緯度を取得し、poi が現在の場所からどれだけ離れているかを計算し、上に挿入したい距離キーに基づいて並べ替え記述子を使用して配列を並べ替えます。このコードは、上記の既存の nsmutablearray への挿入に固執しています
