iOS 7 UIViewController (with navigation bar) doesn't inset UIScrollView

Question

I've got a UINavigationController with a UIViewController showing a navigation bar.

I've specifically set [self setAutomaticallyAdjustsScrollViewInsets:YES];, though this should be YES by default anyway.

I add a UIScrollView:

self.scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:self.scrollView];

However, the UIScrollView's contentInset is {0, 0, 0, 0}, so I am wondering why it doesn't inherit the content inset from the view controller as the documentation states it would.

If I add subviews to the scroll view and set their Y to be self.scrollView.contentInset.top they don't appear below the navigation bar, which is what I am expected.

What am I doing wrong here? It works fine if you start out with a UITableViewController since it correctly inherits the contentInset from the view controller.

Thanks!

The contentInset (and contentOffset) adjustment will only be seen after the view is on screen. Can you confirm that they are still not being set in viewDidAppear or later? — Jason Moore
Ah, that might be there issue here, that I am trying to set it in loadView — runmad
Ah, definitely wouldn't recommend doing more in loadView than creating and assigning something to self.view. — Jason Moore
@runmad My comment previously may have been misleading. What I mean is your view hierarchy must be like this. View (self.view) --->ScrollView --->Other views If you have anything in between self.view and your scrollView [setAutomaticallyAdjustsScrollViewInsets:] will not work i.e. View -->Other views (UIButton, UILabel, UIView etc) -->ScrollView — JLau_cy

self.view = self.scrollView;

Works fine for me. Tested with UIWebview:

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.view = self.webView;
}
