How to prevent UINavigationBar from covering top of view in iOS 7?

Question

After updating to Xcode 5, the navigation bars in all of my app's views have shifted down. Here are some screenshots, the first showing everything in the view as it's pulled down, and the second showing all of it untouched. The search bar should begin where the navigation bar.

Anyone know how I can fix this?

edit: i have tried this previously recommendation:

if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
        self.edgesForExtendedLayout = UIRectEdgeNone;

But it yields very odd results.

This may be because I have a "slide menu" under this view controller that is appearing due to the transparency of the navigation bar.

Answer 1

Set the navigation bar's translucent property to NO:

self.navigationController.navigationBar.translucent = NO;

This will fix the view from being framed underneath the navigation bar and status bar.

If you have to show and hide the navigation bar, then use

 if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
    self.edgesForExtendedLayout = UIRectEdgeNone;   // iOS 7 specific

in your viewDidLoad method.

Answer 2

In iOS 7 by defaults all Controller translucent property value is YES, so you set translucent property NO for this issue.

self.navController.navigationBar.translucent = NO;

Answer 3

You can disable the "Extend edges" in Attribute inspector of View Controller of this screen (as shown in below image) :

Answer 4

This works for swift as well on iOS 8.1

navigationController?.navigationBar.translucent = false

Answer 5

If you want to keep the translucency on your navigationBar, at the end of your viewDidLoad or in your viewWillAppear add this line of code:

[self.view sendSubviewToBack:self.tableView]

Somehow if your scrollView subclass (UITableView, UICollectionView, etc.) is at index 0 in your current view subviews, it will automatically adjust the insets according to your navigationBar. And it shouldn't affect your UI in versions prior to iOS7 either.

EDIT If you initialize your UITableView programmatically, then it is best to add it to the view using this [self.view insertSubview:self.tableView atIndex:0];

Answer 6

Swift 4:

Set following line of code in viewDidLoad method:

self.navigationController?.navigationBar.isTranslucent = false

Answer 7

You can add this method into your view controller as shown on this URL:

-(void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    self.searchBar.frame = 
    CGRectMake(0, self.topOfViewOffset, self.searchBar.frame.size.width, self.searchBar.frame.size.height);
}

Answer 8

Another approach is to set self.automaticallyAdjustsScrollViewInsets = YES; on your view controller. This is enabled by default. But in your case:

I see you are using EGORefreshHeaderView. It plays with contentInset of UITableView. So when you release it, header will reset top inset instead of restore previous value.

Answer 9

The above answers might fix your issue but rise many other issues, for instance: Custom views are not centered by Y because navigation bar becomes opaque hence it pushes down all your views.

Having translucent navigation bar doesn't cause this issue neither it causes the issue you posted about in iOS 11+. However I found no workaround to have it work on all iOS platforms starting from iOS 9.

Answer 10

If you want to have complete control on views and avoid faulty adjustments of iOS, subclass UITableView and adjust the insets (both scroll and indicators) in -(void)willMoveToWindow:(UIWindow *)newWindow. Works for me.

Answer 11

Another option is to open your Info.plist file in source code mode and enter the following info:

<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
<key>UIStatusBarHidden</key>
<true/>

Hope this helps.
