I have a UITableView as a UIView subview. This table view has a UISearchBar, which is working correctly, but it's changing it's position when it becomes first responder:
Code:
self.searchBar = [UISearchBar new];
self.searchBar.delegate = self;
self.searchBar.placeholder = #"Buscar";
self.searchBar.text = #"";
self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
self.searchController.delegate = self;
self.searchController.searchResultsDataSource = self;
self.searchController.searchResultsDelegate = self;
self.tableView.tableHeaderView = self.searchBar;
Is there anyway to avoid this change? I'd like it to remain at the same place when selected.
Thanks!
Here's the solution: http://petersteinberger.com/blog/2013/fixing-uisearchdisplaycontroller-on-ios-7/
UISearchDisplayController is pretty bad on iOS 7.

I ran into a problem where the UISearchController, when it animates the searchBar into the navigationBar, leaves the statusBar transparent and not the same color as the searchBar, like below:
I searched SO, and the below solution inspired by this question
- (void)willPresentSearchController:(UISearchController *)searchController {
self.navigationController.navigationBar.translucent = YES;
}
- (void)willDismissSearchController:(UISearchController *)searchController {
self.navigationController.navigationBar.translucent = NO;
}
fixes the problem for iOS9, but not for iOS8. I tried setting
self.extendedLayoutIncludesOpaqueBars = YES;
but with no effect. Also, setting
self.edgesForExtendedLayout = UIRectEdgeAll;
hides the initial searchBar under the navigationBar, so I cannot use it.
Here's my code for initiating a UISearchController under an opaque UINavigationBar:
UITableViewController *searchResultsController = [[UITableViewController alloc] initWithStyle:UITableViewStylePlain];
searchResultsController.tableView.dataSource = self;
searchResultsController.tableView.delegate = self;
self.searchController = [[UISearchController alloc] initWithSearchResultsController:searchResultsController];
self.searchController.delegate = self;
self.searchController.searchResultsUpdater = self;
self.searchController.searchBar.delegate = self;
self.searchController.searchBar.barTintColor = [UIColor whiteColor];
self.searchController.searchBar.frame = CGRectMake(0.0, 0.0, self.view.frame.size.width, 44.0); // Required for iOS8, not iOS9 though
[self.view addSubview:self.searchController.searchBar];
Any suggestions how to fix this for iOS8?
When adding a UISearchController to a UITableView header view, it is impossible to set the background behind the UISearchBar.
The second picture is showing the view when dragging to the bottom.
The UITableView is set in the Storyboard without any headers.
self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
// Setup appearance
self.searchController.searchBar.barStyle = UIBarStyleBlack;
self.searchController.searchBar.barTintColor = BLUE;
self.searchController.searchBar.tintColor = RED;
// Setup logic
self.searchController.searchBar.scopeButtonTitles = #[ NSLocalizedString(#"students", nil), NSLocalizedString(#"professors", nil), NSLocalizedString(#"rooms", nil) ];
self.searchController.searchBar.delegate = self;
self.searchController.searchResultsUpdater = self;
self.tableView.tableHeaderView = self.searchController.searchBar;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.definesPresentationContext = YES;
I tried adding the background to the storyboard, to the superview, the UITableView, and manually to the UISearchBar.
More code available here.
You can try this:
UIView* topview = [[UIView alloc] initWithFrame:CGRectMake(0, -480, self.view.frame.size.width, 480)];
topview.backgroundColor = BLUE;
[self.tableView addSubview:topview];
I have tested with a UITableViewController and it works fine.
Inspired from this answer
I have gone through all the documentation I can find, but I just can't figure out how to solve this issue. When I click on the search text box, the lightbox comes up, but does not cover the whole screen (looks like it is off by ~64dp). Here are a couple of screenshots.
I have my search stuff inside of a tableViewController

Has anyone had experience fixing this issue?
Here is how I am setting everything up:
self.searchBar = [[UISearchBar alloc] init];
self.searchBar.barTintColor = [UIColor whiteColor];
self.searchBar.delegate = self;
self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
self.searchController.delegate = self;
self.searchController.searchResultsDelegate = self;
self.searchController.displaysSearchBarInNavigationBar = YES;
Turns out I had a self.edgesForExtendedLayout = UIRectEdgeNone; in the viewDidLoad, and that messed EVERYTHING up...
I want to add a UISearchBar to an UIView instead of an UIViewController, the problem is that the init method of UISearchDisplayController needs an UIViewController as contentsController:.
I can see the UISearchBar correctly displayed in the view but if I click in it, the bar disappears. Here is my code I'm currently using:
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
// this was my approach, but this DOES NOT work
UIViewController *results = [[UIViewController alloc] init];
results.view.userInteractionEnabled = NO;
[self insertSubview:results.view aboveSubview:self.menuList];
self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:results];
self.searchController.delegate = self;
self.searchController.searchResultsDataSource = self;
self.searchController.searchResultsDelegate = self;
self.tableView.tableHeaderView = self.searchBar;
Before:
After clicking into search bar:
In swift,
I use hidesNavigationBarDuringPresentation to solve this problem.
This problem seems like after the search bar is clicked, it will automatically hide the bar. And it will be fine after you click outside the view.
I add this line:
self.searchController?.hidesNavigationBarDuringPresentation = false;
Hope it works
I have created a UITableViewController and added a UISearchDisplayController programmatically. There's no storyboard or nib file as I am doing everything programmatically. Everything seems to work perfectly except when I click on the search bar, it animates weirdly and there's some offset left to the bottom of the search bar.
Here's a video of the behaviour.
And here's the code of Table VC:
// Initialize Search Bar
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
self.searchBar.delegate = self;
self.tableView.tableHeaderView = self.searchBar;
self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self];
self.searchController.searchResultsDataSource = self;
self.searchController.searchResultsDelegate = self;
self.searchController.delegate = self;
// Hide the search bar
[self.tableView setContentOffset:CGPointMake(0, 44)];
I also tried [self setEdgesForExtendedLayout:UIRectEdgeNone]; on the UITableViewController's implementation but it created another issue, although it seems to fix the animation by some extent leaving some gap at the top and the same gap at the bottom of search bar.
Edit: One more thing to note—it can be seen in the video that the result table view is properly aligned with the search bar. So is there any problem with the implementation of main table view? They are same but the former is aligned properly so I am guessing there's a problem with the table view. What do you think?
iOS7 makes programmatically adding these elements unnecessarily difficult. After much testing in my own app, here's how I did it inside of my UITableViewController.
// _searchBar
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.view.frame.size.width, 44.0f)];
self.searchBar.delegate = self;
// _searchController
self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:[self searchBar] contentsController:self];
self.searchController.delegate = self;
self.searchController.searchResultsDelegate = self;
self.searchController.searchResultsDataSource = self;
self.searchController.searchResultsTableView.frame = [self.tableView frame];
// _tableView
self.tableView.tableHeaderView = [self.searchController searchBar];
Don't worry about hiding the searchBar, as the OS will reset everything to its original state when you hit cancel.
