Question

I load json-data from my server by using FMDB. The response I get (JSON), I’m storing in a sqlite-database (same string as the response below gets stored in the database). Later on I select that data from the database through FMDB and trying to build up a NSDictionary from it, but can’t get it to work.

The json-response I get from the server looks like below (shortened down the response for this post, so it contains some more…) when I output it through NSLog:

{
response = {
    data = {
        "dbId_1" = {
            1 = {
                current = {
                    weekday = Tuesday;
                };
            };
        };
    };
};
}

This is how I select it from the database and what I want to make a NSDictionary from:

NSString *jsonString = [results stringForColumn:@"json"];

Is it possible to build up everything again to a NSDictionary?

Add JSONKit to your project, #import “JSONKit.h” then go:

NSDictionary *jsonDict = [yourJSONStringFromDB objectFromJSONString];

If you’re using Automatic Reference Counting, then you’ll need to open up your Project Settings > Build Phases > Compiled Sources Panel

Look for “JSONKit.m” line and double click on it, add “-fno-objc-arc” to force no automatic reference counting for this file.
