    <p>Looks like your config contents were output by <code>NSLog</code>, which results in invalid JSON hence assuming that your actual config file is a valid JSON object, following code should get you what you need:</p> <pre><code>//Don't forget to replace "configfile" with your config file name in the project NSString *configPath = [[NSBundle mainBundle] pathForResource:@"configfile" ofType:nil]; NSData *data = [[NSFileManager defaultManager] contentsAtPath:configPath]; NSDictionary *config = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil]; NSArray *ports = [config valueForKeyPath:@"main.inputs.port"]; //ports[0] is 10001 //ports[1] is 10002 </code></pre> <p>Here you can verify if your JSON is valid: <a href="http://jsonlint.com" rel="nofollow">http://jsonlint.com</a>. This is how your valid JSON confi should look like:</p> <pre><code>{ "main": { "delay": "10000", "inputs": [ { "enabled": true, "ip": "127.0.0.1", "port": 10001, "file": "c: \\abc.txt" }, { "enabled": true, "ip": "127.0.0.1", "port": 10002, "file": "c: \\myfile.txt" } ] } } </code></pre> <p>EDIT:</p> <p>I would personally use a model framework rather than just a json parser to save you from a ton of manual work that comes with built-in <code>NSJSONSerialization</code> class. Here are couple of pretty good ones:</p> <p>1) <strong>GitHub Mantle</strong> - <a href="https://github.com/MantleFramework/Mantle" rel="nofollow">https://github.com/MantleFramework/Mantle</a> I use it where ever I can. It is very well written and thought out framework but has a little bit of learning curve involved, which probably is true to any new piece of software.</p> <p>2) <strong>SBJson</strong> - <a href="https://github.com/stig/json-framework" rel="nofollow">https://github.com/stig/json-framework</a> You can use <code>SBJson</code> if you just wanna get the job done, it has been pretty popular, especially before Mantle and other frameworks became available.</p> <p>I hope it helps.</p>

    1. COthanks, but do you know any free and simple JSON parser for objective C?

    3. CO@MartinR : thanks, I use gcc. Which header file should I use so that I can use NSJSONSerialization?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
