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 am trying to add a search bar programmatically to an UIView (not a UITableView). For the moment, I am just trying to set the delegates properly so that when I click the "enter" button, a message is printed:
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
NSLog(#"enter button clicked");
[searchBar resignFirstResponder];
}
I already have some code working for an UITableViewController that I am trying to adapt. It looks like this (I am skipping all the parts of the code that are not relevant to the present discussion):
#property (nonatomic, strong) UISearchController *searchController;
#property (nonatomic, strong) UITableViewController *resultsTableController;
- (void)viewDidLoad {
[super viewDidLoad];
self.resultsTableController = [[SearchResultsController alloc] init];
self.searchController = [[UISearchController alloc] initWithSearchResultsController:self.resultsTableController];
self.searchController.searchResultsUpdater = self;
[self.searchController.searchBar sizeToFit];
self.searchController.delegate = self;
self.searchController.searchBar.delegate = self;
self.definesPresentationContext = YES;
self.tableView.tableHeaderView = self.searchController.searchBar;
}
Now the only line that doesn't transpose to the UIViewController case is the last one
self.tableView.tableHeaderView = self.searchController.searchBar;
My UIViewController is defined with a xib which contains a UIView called myView and a UISearchBar called searchBar. So I tried doing
self.myView = self.searchController.searchBar;
or
self.searchBar = self.searchController.searchBar;
but in the first case the searchBardoesn't even show and in the second case the delegation to self seems lost (nothing happens when I click enter).
What am I doing wrong ?
This is how you would add a UISearchBar to a UIViewController programmatically:
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, kScreenWidth, 40.0)];
self.searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
self.searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
self.searchBar.autoresizingMask = UIViewAutoresizingFlexibleWidth;
self.searchBar.tintColor = kRunnerSearchBarTintColor;
if ([RunnerUtilities isIOS7orAbove]) {
self.searchBar.searchBarStyle = UISearchBarStyleProminent;
[self.searchBar setBarTintColor:[UIColor colorWithRed:185.0/255.0 green:195.0/255.0 blue:202.2/255.0 alpha:0]];
}
self.searchBar.delegate = self;
[self.view addSubview:self.searchBar];
Well, this is no more different than adding it from XIB file. First, search bar is a added as a subview to view of view controller and should be connected to search bar outlet defined in ViewController. Second, UIViewController must be set as delegate of the search bar. Please ensure you are following this and this should work.
EDIT::
If you are trying to use UISearchController within UIViewController, please try with following code:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any custom init from here...
// Create a UITableViewController to present search results since the actual view controller is not a subclass of UITableViewController in this case
UITableViewController *searchResultsController = [[UITableViewController alloc] init];
// Init UISearchController with the search results controller
self.searchController = [[UISearchController alloc] initWithSearchResultsController:searchResultsController];
// Link the search controller
self.searchController.searchResultsUpdater = self;
// This is obviously needed because the search bar will be contained in the navigation bar
self.searchController.hidesNavigationBarDuringPresentation = NO;
// Required (?) to set place a search bar in a navigation bar
self.searchController.searchBar.searchBarStyle = UISearchBarStyleMinimal;
// This is where you set the search bar in the navigation bar, instead of using table view's header ...
self.navigationItem.titleView = self.searchController.searchBar;
// To ensure search results controller is presented in the current view controller
self.definesPresentationContext = YES;
// Setting delegates and other stuff
searchResultsController.tableView.dataSource = self;
searchResultsController.tableView.delegate = self;
self.searchController.delegate = self;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.searchController.searchBar.delegate = self;
}
I have two ways of searching for friends within my app. One of them is a snapchat similar interface where the added friends are shown and possibility of adding a friend is shown with a + sign. I tried adding a search bar somewhere within the area programmatically but got no results of nothing displaying. The code was implemented on my FriendsViewController that I am using and this is the current code I have:
-(void)initialiseSearchBar
{
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
UITableViewController *searchResultsController = [[UITableViewController alloc] initWithStyle:UITableViewStylePlain];
searchResultsController.tableView.dataSource = self;
searchResultsController.tableView.delegate = self;
searchResultsController.tableView.backgroundColor = [UIColor colorWithWhite:0 alpha:0.7];
self.searchController = [[UISearchController alloc] initWithSearchResultsController:searchResultsController];
self.tableView.tableHeaderView = self.searchController.searchBar;
self.searchController.searchResultsUpdater = self;
[self.tableView setContentOffset:CGPointMake(0, 0)];
self.edgesForExtendedLayout = UIRectEdgeNone;
self.searchResults = [NSMutableArray array];
}
Any idea what I have done wrong or should fix? Also I am planning on releasing with iOS 7 compatibility and up all the way until 8.1, I have worries that the terms might be different or there is something depreciated that I do not know of.
You've allocated it but you haven't added it to the view itself unless it was made in storyboard (which you clearly state you didn't do) see my answer on another question... you have to add it as a subview somehow:
Adding A Search Bar
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 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.
I have a UIViewController in which I want to show a tableview with the serchBar.
//viewDidLoad
_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0,
0,
SCREEN_WIDTH(),
SCREEN_HEIGHT())
style:UITableViewStylePlain];
_tableView.delegate = self;
_tableView.dataSource = self;
[self.view addSubview:_tableView];
// adding uisearch bar
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
_tableView.tableHeaderView = searchBar;
//
searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
searchDisplayController.delegate = self;
searchDisplayController.searchResultsDataSource = self;
The issue happens when I click inside the uisearch bar so that the animation starts and it looks like it has a 20px unwanted offset.
In your Storyboard, select the problematic controller, look at the Attributes tab and try to edit these settings:
Under Top Bars
Under Opaque Bars
I've solved a similar problem by unflagging these settings.
I found what is causing this issue. Seems that the animation gets messed up when you set navigationBar.translucent to NO. If you make your navigationBar translucent, everything should work fine, but this is definitely not an ideal solution. I'm going to try and find a workaround.
UITableView *_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0,
64,
self.view.frame.size.width,
self.view.frame.size.height)
style:UITableViewStylePlain];
_tableView.delegate = self;
_tableView.dataSource = self;
[self.view addSubview:_tableView];
// adding uisearch bar
UISearchBar* searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
_tableView.tableHeaderView = searchBar;
//
UISearchDisplayController* searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
searchDisplayController.delegate = self;
searchDisplayController.searchResultsDataSource = self;
and I just embade my controller with UINavigationcontroller and its working quite well..
You can cancel animation by subclassing UISearchDisplayController and adding this:
- (void)setActive:(BOOL)visible animated:(BOOL)animated
{
if(self.active == visible) return;
[self.searchContentsController.navigationController setNavigationBarHidden:YES animated:NO];
[super setActive:visible animated:animated];
[self.searchContentsController.navigationController setNavigationBarHidden:NO animated:NO];
if (visible) {
[self.searchBar becomeFirstResponder];
} else {
[self.searchBar resignFirstResponder];
}
}
codyko gave me an idea. It was the because the navigation bar was no translucent. So I set it to translucent on this view controller and rest when I left with the following code:
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
self.navigationController.navigationBar.translucent = NO;
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
self.navigationController.navigationBar.translucent = YES;
}
Now that left the navigation bar on this controller slightly faded, so I added a UIView the same color as my navbar just behind it to make it look opaque. I know it isn't perfect but it works nicely.
As a reminder for anyone with similar issues. I needed to add this line that fixed things:
self.edgesForExtendedLayout = UIRectEdgeNone;
Why are you creating the searchBar programmatically instead of in the StoryBoard ?
I'm currently using searchBar, added in storyboard and it's work fine ( I have to change the contentOffset )
I have applied your code,, It works fine for me,, Just hide you navigation bar and start the search bar from y = 20, instead of y = 0;
