How to add the UISegmentedControl in UINavigationBar? - ios

Question

I have tried to add the UISegmentedControl to the bottom of UINavigationBar with title. But i cannot add it and I cannot add UISegmentedControl in the tableView.headerView,because i need the search bar in the tableView.headerView, so there is just one solution that i need to add UISegmentedControl to the bottom of UINavigationBar. Anyone have another idea that i can solve this situation?
Here is the code that I have tried(with Swift):
class searchingViewController: UITableViewController{
override func viewDidLoad() {
var items: [AnyObject] = ["Searching Method A", "Searching Method B"]
var searchSC:UISegmentedControl!
searchSC.frame = CGRectMake(0, 0, frame.width - 20, 30)
searchSC.selectedSegmentIndex = 1
searchSC.backgroundColor = UIColor(white: 1, alpha: 1)
searchSC.layer.cornerRadius = 5.0
navigateUIToolBar = UIToolbar(frame: CGRectMake(frame.minX + 10, ios7_8Info.getStatusBarHeight()+self.navigationController!.navigationBar.frame.height+frame.minY+(21/2),
frame.width - 20, 30))
navigateUIToolBar.addSubview(searchSC)
self.navigationController?.navigationBar.addSubview(navigateUIToolBar)
}
}

To add segment control in UINavigationBar in Swift 5
let segment: UISegmentedControl = UISegmentedControl(items: ["First", "Second"])
segment.sizeToFit()
if #available(iOS 13.0, *) {
segment.selectedSegmentTintColor = UIColor.red
} else {
segment.tintColor = UIColor.red
}
segment.selectedSegmentIndex = 0
segment.setTitleTextAttributes([NSAttributedString.Key.font : UIFont(name: "ProximaNova-Light", size: 15)!], for: .normal)
self.navigationItem.titleView = segment

To put it in the navigationBar has a right left and title view for such things... accessed using....
self.navigationItem.titleView = mySegmentedControl
for future reference....
self.navigationItem.rightBarButtonItem
self.navigationItem.leftBarButtonItems // for adding an Array of items
To add it below the navigation view but have it static.. add it to the viewController.view... Are you using a UITableViewController? If so maybe switch to a UIViewController and add a tableView then your toolbarview as subviews to that self.view.

I think you are looking for this.
let searchVC = self.storyboard?.instantiateViewController(withIdentifier:"idofcontroller")
let searchController = UISearchController(searchResultsController: searchVC)
searchController.searchResultsUpdater = self
searchController.obscuresBackgroundDuringPresentation = false
searchController.searchBar.placeholder = "Search"
navigationItem.searchController = searchController
definesPresentationContext = true
searchController.searchBar.scopeButtonTitles = ["News", "Photos", "Videos"]
searchController.searchBar.delegate = self

This is how I do it in Objective C (sorry, I haven't learned Swift yet):
- (void)viewDidLoad
{
[super viewDidLoad];
self.viewControllers = [self segmentViewControllers];
self.segmentedControl = [[UISegmentedControl alloc] initWithItems: [self.segmentedControl addTarget: self
action: #selector(segmentClicked:)
forControlEvents: UIControlEventValueChanged];
CGFloat topOffset = self.navigationController.navigationBar.frame.size.height + [UIApplication sharedApplication].statusBarFrame.size.height;
self.toolbar = [[UIToolbar alloc] initWithFrame: CGRectMake(0, topOffset, self.navigationController.navigationBar.frame.size.width, kDefaultViewHeight)];
self.toolbar.delegate = self;
self.navigationController.navigationBar.backgroundColor = [UIColor whiteColor];
self.toolbar.backgroundColor = [UIColor whiteColor];
self.toolbar.clipsToBounds = YES;
UIBarButtonItem *segmentedControlItem = [[UIBarButtonItem alloc] initWithCustomView: self.segmentedControl];
UIBarButtonItem *flexibleItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace
target: nil
action: nil];
[self.toolbar setItems: #[flexibleItem, segmentedControlItem, flexibleItem] animated: YES];
[self.navigationController.view addSubview: self.toolbar];
self.segmentedControl.selectedSegmentIndex = 0;
}
And in UITableViewController (one of the segmentViewControllers):
self.tableView.contentInset = UIEdgeInsetsMake(topOffset, 0, 0, 0);
CGRect currentFrame = self.tableView.frame;
[self.tableView setFrame: CGRectMake(currentFrame.origin.x,
currentFrame.origin.y,
currentFrame.size.width,
currentFrame.size.height + [UIApplication sharedApplication].statusBarFrame.size.height)];

You can also add the segment control to a search bar, not the navigation item. If you're like me, I needed a large title + search bar + navigation item, which would be impossible with the current top answer.
#Abhishek 's answer is close. You would do something like the following:
// Create the search controller
let searchController = UISearchController(searchResultsController: nil)
searchController.searchResultsUpdater = self
searchController.obscuresBackgroundDuringPresentation = false
searchController.searchBar.scopeButtonTitles = ["Option 1", "Option 2"]
// Make sure the scope bar is always showing, even when not actively searching
searchController.searchBar.showsScopeBar = true
// Make sure the search bar is showing, even when scrolling
navigationItem.hidesSearchBarWhenScrolling = false
// Add the search controller to the nav item
navigationItem.searchController = searchController
definesPresentationContext = true
#Gurjit Singh, the line with .showsScopeBar = true is the solution to your problem.

Answer 6

you can custom navigationItem's titleView, like this:
self.navigationItem.titleView = segmentview
you should not add subview to the navigationbar, for after push or pop UIViewcontroller ,the subview is still exsit on the navigationbar.
