Overlay area stays on top after searching a list UIView

Question

I have a UIView with a list of items. When I click the search bar the keyboard comes up and the rest of the screen contains a grey overlay.

When I click on the grey overlay the keyboard disappears, however the overlay area stays on top and is not disappearing. What is the root of cause of this problem? How can I resolve it?

Answer 1

Check it:-

Write this in console:- by giving breakpoint in the view controller

 po [self.view subviews]

(id) $1 = 0x0a3155f0 <__NSArrayM 0xa3155f0>(
<ATShadowTableView: 0xc341600; baseClass = UITableView; frame = (0 44; 320 411); clipsToBounds = YES; gestureRecognizers = <NSArray: 0xa627200>; layer = <CALayer: 0xa626d30>; contentOffset: {0, 0}>,
<UISearchBar: 0xa618f40; frame = (0 0; 320 44); text = ''; layer = <CALayer: 0xa619040>>,
<UIControl: 0xa329fc0; frame = (0 44; 320 455); alpha = 0.8; opaque = NO; animations = { opacity=<CABasicAnimation: 0xa32b4e0>; }; layer = <CALayer: 0xa32a060>>
)

Last object (UIControl) in self.subview is what we want to remove. So

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
...
    [self performSelector:@selector(removeOverlay) withObject:nil afterDelay:.01f];
}

- (void)removeOverlay
{
    [[self.view.subviews lastObject] removeFromSuperview];
}

Try using this:

[searchCon setActive:NO animated:YES];

where searchCon is your UISearchDisplayController.

Hope it helps
