iOS 7 + iPad：UISearchBar导致导航栏内容与状态栏混合

Question

This happens only on iPad:

• Put a simple UISearchBar in a UIViewController with a UINavigationController
• [optional] Set bar tint color: self.navigationController.navigationBar.barTintColor = [UIColor clearColor];
• Run the app.
• Tap on search bar (triggers animation)
• Now status bar is mixed with the top of the navigation bar content (ie title, buttons)

Before tap:

After tapping the search bar:

The problem happens with any color, but using [UIColor clearColor] as in the photos attached makes it easier to see the issue.

Any solutions will be great, although I prefer something more elegant than hiding the navigation bar title and buttons each time.

EDIT

This bug happens only when using the following code in viewdidLoad :

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

Answer 1

I think I got once the same issue. If you are using storyboards, check please that all the outlets are set:

That fixed the animation...

Answer 2

A workaround I used eventually:

- (BOOL)prefersStatusBarHidden
{
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
        return self.searchDisplayController.isActive;

    return NO;
}

This way when user searches it hides the status bar.

Answer 3

有完全相同的问题，修复结果是一行：

self.searchDisplayController.searchBar.translucent = NO;

Answer 4

I had the same problem. The following code worked:

self.edgesForExtendedLayout = UIRectEdgeTop;
