Google Places API Doesn't return a response

I follow the Tutorial on the Internet, and I have 2 methods that send a request to the Google Places API. Unfortunately, I am trying to get an answer; it does not work. I have several debug numbers in the code. However, here is the code.

-(void) queryGooglePlaces{
    NSString *url = @"https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=myKey";

    //Formulate the string as a URL object.
    NSURL *googleRequestURL=[NSURL URLWithString:url];
    NSLog(@"1.5");
    // Retrieve the results of the URL.
    dispatch_async(kBgQueue, ^{
        NSData* data = [NSData dataWithContentsOfURL: googleRequestURL];
        [self performSelectorOnMainThread:@selector(fetchedData:) withObject:data waitUntilDone:YES];
    });
    NSLog(@"2");
}

-(void)fetchedData:(NSData *)responseData {
    //parse out the json data
    NSError* error;
    NSDictionary* json = [NSJSONSerialization 
                          JSONObjectWithData:responseData 

                          options:kNilOptions 
                          error:&error];

    //The results from Google will be an array obtained from the NSDictionary object with the key "results".
    NSArray* places = [json objectForKey:@"results"]; 

    //Write out the data to the console.
    NSLog(@"Google Data: %@", places);
    NSLog(@"3");
}

In the log, the output is as such:

2012-08-03 16:40:12.411 sCode[25090:1a303] 1.5
2012-08-03 16:40:12.411 sCode[25090:1a303] 2
