searchDisplayControllerWillEndSearch goes out of the UIView when end searching - ios

Question

I've a UIView in which I've placed a UISearchBar and a UIButton below are the screenshots that explains the problem:
^This is how it appears when I first run the app
^This is how it gets when I want to enter the text
^Finally this is the size it gets after I end the searchThe most important point here is that I'm not using UINavigationBar the red is a UIView. I've haven't coded anything for it's UI, I just placed it in the .xib and set it via autoResizing. They only this I wrote for UISearchBar was [_searchBarTop setBackgroundImage:[UIImage new]]; which was just to get the background image vanished.I've tried self.searchBarTop.clipsToBounds = YES; and this
- (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller
{
self.searchDisplayController.searchBar.translatesAutoresizingMaskIntoConstraints = YES;
[self.searchDisplayController setActive:NO animated:YES];
}
I'm using searchdisplaycontroller and want to use that
But it's still the same. Any suggestions?

Answer 1

If you're using a simple UISearchBar in a UIView, you don't need to use UISearchController per sè. You can simply use UISearchBar and it's respective delegates instead.
As for the resizing issue, I think you have the autoresizing at flexible width, whereas you need static width, with static sides. Apply this to both your UIView and the embedded UISearchBar. That should fix your issue. Let me know if the problem persists.
If autoresizing doesn't work, you can just force it back like this:
-(void)searchBarTextDidEndEditing:(UISearchBar *)searchBar {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.01 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
CGRect frame = self.searchBarTop.frame;
frame.origin.x = 33;
frame.size.width = self.view.frame.size.width - 41;
[UIView animateWithDuration:0.5 animations:^{
self.searchBarTop.frame = frame;
}];
});
}

UISearchDisplayController was first deprecated in iOS 8.0, as indeed was UISearchDisplayDelegate. You should use UISearchController its delegate, UISearchControllerDelegate and its searchBar property instead.
EDIT - Add Example
// your class needs to conform to the following protocols
<UISearchResultsUpdating, UISearchControllerDelegate>
// define property for your search controller
#property (nonatomic) UISearchController *mySearchController;
// instantiate the search controller - in viewDidLoad should work
// if you want to handle results manually the searchResultsController can be nil, or you can set it to
self.mySearchController = [[UISearchController alloc]initWithSearchResultsController:nil];
[self.mySearchController.searchBar sizeToFit];
self.mySearchController.searchResultsUpdater = self;
self.mySearchController.delegate = self;
self.mySearchController.dimsBackgroundDuringPresentation = NO;
// add the searcher to a properly constrained "Container" or "wrapper" UIView
[self.containerView addSubView:self.mySearchController.searchBar];
[self.mySearchController.searchBar sizeToFit];
self.definesPresentationContext = YES;
you can then respond to the input in the search bar by implementing the UISearchResultsUpdating protocol's required method:
- (void)updateSearchResultsForSearchController:(UISearchController *)searchController{
NSString *text = searchController.searchBar.text;
/// do whatever you need to with the text typed in to the search bar
}
And Finally, always read Apple's documentation
