iOS UIScrollView does not scroll a UIImageView

[Tex-Twil]

Hi,
I have a UIScrollView that is setup in the Interface Builder and take the entire screen. I want to add an UIImageView so that the user can scroll horizontally and vertically through the image.

In my viewDidLoad method I've added this:

    self.imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"01.jpeg"]];

    [self.view addSubview:self.imageView];
    self.scrollView.contentSize = self.imageView.image.size;
    self.scrollView.scrollEnabled = YES;
    self.scrollView.clipsToBounds = YES;

    NSLog(@"self.scrollView.frame %@", NSStringFromCGRect(self.scrollView.frame));
    NSLog(@"self.scrollView.bounds %@", NSStringFromCGRect(self.scrollView.bounds));
    NSLog(@"self.imageView.frame %@", NSStringFromCGRect(self.imageView.frame));
    NSLog(@"self.scrollView.contentSize %@", NSStringFromCGSize(self.scrollView.contentSize));

But the scroll view is not scrolling The log output is

self.scrollView.frame {{0, 0}, {320, 568}}
self.scrollView.bounds {{0, 0}, {320, 568}}
self.scrollView.contentSize {2048, 1365}
self.imageView.frame {{0, 0}, {2048, 1365}}

what did I do wrong ?

cheers

You are adding your imageView to the wrong parent view. Try adding it to the scrollView. Also I don't see where you are adding your scrollView to it's parent. Perhaps via a XIB file?

as xStep said, in this line

[self.view addSubview:self.imageView];

you add the image view to your view controller's view but you should be adding it like

[self.scrollView addSubview:self.imageView];

Note: this is assuming you have connected the UIScrollView as a property named scrollView through the interface builder
