title: UIImageView (created programmatically) is not showing up
body: <p>I am trying to add an UIImageView programatically to my modal view controller and the image simply does not show up. I only see the white background. The rest is working fine as I'm able to load or dismiss the view. My code below:</p>
  
  <pre><code>[super viewDidLoad];
  // Do any additional setup after loading the view.
  self.view.backgroundColor = [UIColor whiteColor];
  
  UIImageView *imageView = [[[UIImageView alloc] init] initWithFrame:CGRectMake(100, 200, 100, 100)];
  imageView.image = [UIImage imageNamed:@"IMG_0352.PNG"];
  [self.view addSubview:imageView];
  
  
  UISwipeGestureRecognizer *swipeleft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
  swipeleft.direction = UISwipeGestureRecognizerDirectionLeft;
  [self.view addGestureRecognizer:swipeleft];
  
  UISwipeGestureRecognizer *swiperight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
  swiperight.direction = UISwipeGestureRecognizerDirectionRight;
  [self.view addGestureRecognizer:swiperight];
  
  
  UIBarButtonItem *dismiss_btn = [[UIBarButtonItem alloc] initWithTitle:@"Start App" style:UIBarButtonItemStylePlain target:self action:@selector(dismissModal:)];
  
  self.navigationItem.rightBarButtonItems = [NSMutableArray arrayWithObjects:dismiss_btn, nil];
  </code></pre>
