Uisearchcontroller Disable Cancel Uibarbuttonitem

UISearchController disable cancel UIBarButtonItem

Updated in light of comments

UISearchBar has a property (see the Apple docs) which determines whether the cancel button is displayed:

self.searchBar.showsCancelButton = false;

But, as per OP comments, this does not work, because the searchController keeps switching the cancel button back on. To avoid this, create a subclass of UISearchBar, and override the setShowsCancelButton methods:

@implementation MySearchBar

-(void)setShowsCancelButton:(BOOL)showsCancelButton {
    // Do nothing...
}

-(void)setShowsCancelButton:(BOOL)showsCancelButton animated:(BOOL)animated {
    // Do nothing....
}

@end

To ensure this subclass is used by the searchController, we also need to subclass UISearchController, and override the searchBar method to return an instance of our subclass. We also need to ensure that the new searchBar activates the searchController - I've chosen to use the UISearchBarDelegate method textDidChange for this:

@interface MySearchController ()  <UISearchBarDelegate> {
UISearchBar *_searchBar;
}
@end

@implementation MySearchController

-(UISearchBar *)searchBar {
    if (_searchBar == nil) {
        _searchBar = [[MySearchBar alloc] initWithFrame:CGRectZero];
        _searchBar.delegate = self;
    }
    return _searchBar;
}

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
    if ([searchBar.text length] > 0) {
        self.active = true;
    } else {
        self.active = false;
    }
}
@end

Finally, change your code to instantiate this subclass:

self.searchController = [[MySearchController alloc] initWithSearchResultsController:self.resultsViewController];

(You will obviously need to import the relevant header files for these subclasses).

How to disable cancel button of UISearchController.seachBar when i tap at searchBar?

You can create a custom class and subclass UISearchBar and UISearchViewController.
For example:-

class CustomizedSearchBar: UISearchBar {
    override func layoutSubviews() {
        super.layoutSubviews()
        setShowsCancelButton(false, animated: false)
    }
}

Now Create Object of the CustomizedSearchBar and use it within other viewController.

Or you can create a customized searchViewController as follows:

class CustomizedSearchController: UISearchController, UISearchBarDelegate {

    lazy var _searchBar: CustomSearchBar = {
        [unowned self] in
        let result = CustomSearchBar(frame: CGRectZero)
        result.delegate = self

        return result
    }()

    override var searchBar: UISearchBar {
        get {
            return _searchBar
        }
    }
}

Hiding Cancel button on search bar in UISearchController

I ended up subclassing both UISearchBar and UISearchController as suggested:

CustomSearchBar.swift

import UIKit

class CustomSearchBar: UISearchBar {

    override func layoutSubviews() {
        super.layoutSubviews()
        setShowsCancelButton(false, animated: false)
    }
}

CustomSearchController.swift

import UIKit

class CustomSearchController: UISearchController, UISearchBarDelegate {

    lazy var _searchBar: CustomSearchBar = {
        [unowned self] in
        let result = CustomSearchBar(frame: CGRectZero)
        result.delegate = self

        return result
    }()

    override var searchBar: UISearchBar {
        get {
            return _searchBar
        }
    }
}

Cancel Button in UISearchController

You need to set the UISearchController searchBar's delegate. Once you have done this, the addition of the delegate method searchBarCancelButtonClicked: will properly be called.

self.searchController.searchBar.delegate = self;

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
}
