NSMutableURLRequest returning null with POST

Question

As per the title, I believe NSMutableURLRequest is returning null when I add in POST request? My server side is all set up and I am able to curl -F "test=test" 127.0.0.1 with my desired result.

As you can see from the methods below I have placed a few NSLogs for error testing. The didReceiveResponse and connectionDidFinishLoading methods worked however didReceiveData failed to call. Similar as to if I didn't place a POST message when I used curl and results in nothing. From this it leads me to think that I have missed something in the viewDidLoad method.

I have also added how I send the response from the server using json encoding at the very bottom.

So have I missed something?

- (void)viewDidLoad {
    NSString *yourPostString = [NSString stringWithFormat:@"test=test"];
    dataWebService = [NSMutableData data];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://127.0.0.1/"]];
    NSString *postLength =  [NSString stringWithFormat:@"%d", [yourPostString length]];

    [request addValue:@"text/html; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue:postLength forHTTPHeaderField:@"Content-Length"];    
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:[yourPostString dataUsingEncoding:NSUTF8StringEncoding]];

    myConnection = [NSURLConnection connectionWithRequest:request delegate:self];
    [myConnection start];  
}

 - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse     *)response {
    [dataWebService setLength:0];
    NSLog(@"Received Response");   
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [dataWebService appendData:data];
    NSLog(@"working %@", data);
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    NSString *responseString = [[NSString alloc] initWithData:dataWebService encoding:NSUTF8StringEncoding];
    NSLog(@"Response: %@",responseString);
}

Here is the send response function.

function sendResponse($status = 200, $body = '', $content_type = 'text/html'){
    $status_header = 'HTTP/1.1 ' . $status . ' ' . getStatusCodeMessage($status);
    header($status_header);
    header('Content-type: ' . $content_type);
    echo $body;
}

Reqests Content-Type should be set to application/x-www-form-urlencoded
