LITjson issue on iOS, other JSON scripts to use for this?

I’m using LITJson on iOS to take JSON output from a server and fill out a game with the content i receive.

The code works the first time around, but on second execution fails, and it looks like its a known bug with the JsonMapper.ToObject($string) command specifically.

The JSON file i have has an array, with multiple items in it, so whichever JSON plugin/script is out there that works with iOS would need to support nested data (most should). I’ve seen Boomlagoons, MiniJSON and JsonFX, but i figured i’d ask here for users experiences with these 3, and possibly others, on iOS and Android.

The JSON i’m trying to parse looks like this:

{
    "shot":[
             {
             "id":"2",
             "version":"1",
             "shot_type":"_3D",
             "disp_type":"main",
             "sort_order":"150",
             "display_name":"Dragon",
             "display_info":"Fiery and ready to fly!",
             "web_store":"https://URL/id2_dragon-01_store.unity3d",
             "web_store_version":"1",
             "web_content":"https://URL/id2_dragon-01_shot.unity3d",
             "web_content_version":"1",
             "ios_store":"https://URL/iphone_id2_dragon-01_store.unity3d",
             "ios_store_version":"1",
             "ios_content":"https://URL/iphone_id2_dragon-01_shot.unity3d",
             "ios_content_version":"1",
             "android_store":"https://URL/android_id2_dragon-01_store.unity3d",
             "android_store_version":"1",
             "android_content":"https://URL/android_id2_dragon-01_shot.unity3d",
             "android_content_version":"1",
             "preview":"https://URL/id2_dragon-01_preview.ogv",
             "result":""
             },
             {
             "id":"3",
             "version":"1",
             "shot_type":"_3D",
             "disp_type":"main",
             "sort_order":"200",
             "display_name":"T-Rex",
             "display_info":"King of the Dinosaurs!",
             "web_store":"https://URL/id3_trex-01_store.unity3d",
             "web_store_version":"1",
             "web_content":"https://URL/id3_trex-01_shot.unity3d",
             "web_content_version":"1",
             "ios_store":"https://URL/iphone_id3_trex-01_store.unity3d",
             "ios_store_version":"1",
             "ios_content":"https://URL/Trex-01/iphone_id3_trex-01_shot.unity3d",
             "ios_content_version":"1",
             "android_store":"https://URL/Trex-01/android_id3_trex-01_store.unity3d",
             "android_store_version":"1",
             "android_content":"https://URL/Trex-01/android_id3_trex-01_shot.unity3d",
             "android_content_version":"1",
             "preview":"https://URL/id3_trex-01_preview.ogv",
             "result":""
             }
    ]
}

LITJson made it quite easy to access the children of the array as so:

for(int i = 0; i<jsonShots["shot"].Count; i++)
    {
         shot = new ShotItem();
         shot.id = Convert.ToInt16(jsonShots["shot"][i]["id"].ToString());
         shot.version = Convert.ToInt16(jsonShots["shot"][i]["version"].ToString());
         shot.shot_type = jsonShots["shot"][i]["shot_type"].ToString();
         shot.disp_type = jsonShots["shot"][i]["disp_type"].ToString();
         shot.sort_order = Convert.ToInt16(jsonShots["shot"][i]["sort_order"].ToString());
         shot.display_name = jsonShots["shot"][i]["display_name"].ToString();
         shot.display_info = jsonShots["shot"][i]["display_info"].ToString();
         shot.preview = jsonShots["shot"][i]["preview"].ToString();
         shot.result = jsonShots["shot"][i]["result"].ToString();
    }

Super simple, and easy to cast the JSON data directly to C# variables.

Do any of the above (or other) Json scripts do something similar?

I’m also open to changing the JSON structure to get back a different result if the above isn’t formatted in a JSON compliant manner as i’m fairly new to JSON as a format.

Thanks in advance for any help/information.

Sorry to bring this old topic up, But did you found a workaround for this problem? I’m experiencing a similar situation too. It works fine at the first run, but tends to hang at the next execution.

Well I figured the solution. JsonMapper.ToObject($string) doesn’t support non-generics on iOS. So you have to use generic type with () for ToObject() function of the jsonMapper.
