Why does NSData stay nil after loading from a valid url?

@interface ViewController : UIViewController
{   
    __strong IBOutlet UIImageView *testImageView;
}

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSData *imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: @"http://news.bbcimg.co.uk/media/images/79790000/jpg/_79790768_hi024951574.jpg"]];
    // imageData => nil ???
    testImageView = [[UIImageView alloc] initWithImage:[UIImage imageWithData: imageData]];

}

@end

I don't understand why it imageData

stays at zero even though the url exists. Is it because I am doing it from a simulator? Thanks to

UPDATE:

enter image description here Not really sure why I am getting NSFileReadUnknownError = 256

After trying the code you provided, I have no problem showing the image.

It looks like the problem lies with your local network environment.



I know this may sound silly, but I recommend you reset and reload the iOS simulator . I experienced a bug that prevents the simulator from connecting correctly after sleeping and waking up the Mac . Xcode 6.1, Yosemite.

Also, check if you are connected via a proxy or if your file is /etc/hosts

understandable regarding the bbcimg.co.uk domain. Just a common common sense test.
