I want the display the output of a URl using NSLog.

ViewController.h

```
@interface ViewController : UIViewController{
NSURLSession *session;
NSString *londonWeatherUrl;
NSURLRequest *request;
}

```

ViewController.m

```
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

londonWeatherUrl = @"http://api.openweathermap.org/data/2.5/weather?q=London,uk&appid=2de143494c0b295cca9337e1e96b00e0";

request = [NSURLRequest requestWithURL:
                         [NSURL URLWithString:londonWeatherUrl]];

[[session dataTaskWithURL:[NSURL URLWithString:londonWeatherUrl]
        completionHandler:^(NSData *data,
                            NSURLResponse *response,
                            NSError *error) {}] resume];

session = [NSURLSession sharedSession];
NSLog(@"%@",);  // what goes here ?
}

```

Can someone tell me what do i need to have inside NSLog so that the output of that URL is displayed in the log.
Sorry, i am a beginner in objective C.
