Question

I want to have an UIImageView in an UIScrollView. But I it doesn’t show any picture when I load it. My code looks like this in my viewController in the function viewDidLoad:

UIImage *image = [UIImage imageNamed:@"plan.gif"];
imageView = [[UIImageView alloc] initWithImage:image];
scrollView = [[UIScrollView alloc] init];
[scrollView addSubview:imageView];
scrollView.contentSize = image.size;
[self updateUI];

In my didFinishLaunchingWithOptions:

TestAppViewController *tavc = [[TestAppViewController alloc] init];
[self.window addSubview:tavc.view];

Answer 1

1) Check that your image name @"plan.gif" is correct. Double-check.
2) Init your UIImageView with a frame and add the image later.

imageView = [[UIImageView alloc] initWithFrame:
   CGRectMake(0,0,scrollView.frame.size.width, scrollView.frame.size.height)]; 
// or choose another size
imageView.image = [UIImage imageNamed:@"plan.gif"];
