Navigation Controller is rendered over the view I navigated to

Question

Have you guys stumbled up on this issue ?

Basically in iOS 7 Navigation Controller is rendered over the sub-view I navigated to.

In iOS 6 view I navigate to is enclosed between navigation bar and footer. In iOS 7 it looks like sub-view is rendered full-screen, under navigation bar and footer. As result user don't see it.

Here is how I navigate to subview

BRSMyListSubViewController *tagsInfoVC = [[BRSMyListSubViewController alloc] initWithCheckinsList:self.checkinsList
                                                                                selectedTag:[self tagByIndexPath:indexPath]];

[self.navigationController pushViewController:tagsInfoVC animated:YES];

Here is how I initialize it in viewDidLoad

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Settings" style:UIBarButtonItemStyleBordered target:self action:@selector(settings:)];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStyleBordered target:self action:@selector(logout:)];

For what it's worth I should also mention that sub-view is defined in XIB using Autolayout. Here is source of my XIB: http://pastebin.com/6RR0zYu4

And finally here is how it looks in iOS 6

And in iOS 7

Any thoughts ?

Answer 1

Well, I figured it out.

In your sub-view (BRSMyListSubViewController in my case), in viewDidLoad, you need to set one of these two

self.edgesForExtendedLayout = UIRectEdgeNone;
self.automaticallyAdjustsScrollViewInsets = NO;

OR

self.edgesForExtendedLayout = UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars = YES;

Interestingly enough in root view controller these value are set to default UIRectEdgeAll, NO and YES respectively but its tableView is NOT under navbar and footer.

I don't know why it's so illogical.

It's also strange that edgesForExtendedLayout has to be mixed with one of two other properties even though it's clearly responsible for the behavior.

PS. For those who wants to run it on iOS 6. Surruound the code with if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
