    copied!<p>I did a few tests with TouchJSON last night and it worked pretty well in general for simple cases. I'm using the following code to read some JSON content from a file, and deserialize it:</p> <pre><code>NSString *jsonString = [[NSString alloc] initWithContentsOfFile:@"data.json"]; NSData *jsonData = [jsonString dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary *items = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&amp;error]; NSLog(@"total items: %d", [items count]); NSLog(@"error: %@", [error localizedDescription]); </code></pre> <p>That works fine if I have a very simple JSON object in the file (i.e. a dictionary):</p> <pre><code>{"id": "54354", "name": "boohoo"} </code></pre> <p>This way I was able to get access to the array of values, as I wanted to get the item based on its index within the list:</p> <pre><code>NSArray *items_list = [items allValues]; NSString *name = [items_list objectAtIndex:1]; </code></pre> <p><em>(I understand that I could have fetched the name with the dictionary API)</em></p> <p>Now I would like to deserialize a semi-complex JSON string, which represents an array of dictionaries. An example of such a JSON string is below:</p> <pre><code>[{"id": "123456", "name": "touchjson"}, {"id": "3456", "name": "bleh"}] </code></pre> <p>When I try to run the same code above against this new content in the data.json file, I don't get any results back. My NSLog() call says "total items: 0", and no error is coming back in the NSError object.</p> <p>Any clues on what is going on? I'm completely lost on what to do, as there isn't much documentation available for TouchJSON, and much less usage examples.</p>
