Question

Feeding the json-parser with the this data: http://mapadosradares.com.br/api/get_initial_load yields this error: Token ‘start of array’ not expected after outer-most array or object

Here is my code:

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    NSLog(@"Connection didReceiveData of length: %u", data.length);

    // Printing the received data
    size_t length = [data length];
    unsigned char aBuffer[length];
    [data getBytes:aBuffer length:length];
    //aBuffer[length - 1] = 0;
    NSLog(@"\n\n\n\n%s\n\n\n\n", aBuffer);

    SBJsonStreamParserStatus status = [parser parse:data];

    if (status == SBJsonStreamParserError) {
        NSLog(@"Parser error: %@", parser.error);

    } else if (status == SBJsonStreamParserWaitingForData) {
        NSLog(@"Parser waiting for more data");
    }
}

As far as I can tell the JSON is perfectly fine. Any thoughts?

UPDATE:

Here’s the parser initalization:

- (void) getInitialLoad
{
    adapter = [[SBJsonStreamParserAdapter alloc] init];
    parser = [[SBJsonStreamParser alloc] init];

    adapter.delegate = self;
    parser.delegate = adapter;

    NSString *url = @"http://mapadosradares.com.br/api/get_initial_load";
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]
                                             cachePolicy:NSURLRequestUseProtocolCachePolicy    timeoutInterval:60.0];
    connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
}

Are you properly initializing the parser between requests? You haven’t shown your code, but it seems like this would be a reasonable error to expect if you ran two successive calls to the feed through the parser.

By the way, I ran the feed output through the excellent JSON parser at http://jsonlint.com and it does appear to be fine.
