IOS, fast. How do I make a floating search bar with a dropdown like this? (Image included)

to make a search bar like this you want to insert a button in the navbar controller and set the background image to be search.png

(your image). so when the user clicks on that button, set the target as searchbar

. please check below code for reference.

First of all, set the delegate method to a file .h

.

@interface FriendsViewController : UIViewController <UISearchDisplayDelegate,UISearchBarDelegate,UIAlertViewDelegate>
 @property (nonatomic, strong) UIButton *searchButton;
 @property (nonatomic, strong) UIBarButtonItem *searchItem;
 @property (nonatomic, strong) UISearchBar *searchBar;
 @property (strong, nonatomic) UISearchController *searchController;
 @property (strong, nonatomic) UISearchDisplayController *d1;

      

        
        
        
      

    

then click the "Insert" button in the search bar.

- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
UIButton *btn=[[UIButton alloc]initWithFrame:CGRectMake(279,9,25, 25)];
[btn setImage:[UIImage imageNamed:@"search"] //put here your searchimage
forState:UIControlStateNormal];
[btn setTitle:@"" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(clickme:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barbtn=[[UIBarButtonItem alloc]initWithCustomView:btn];
self.tabBarController.navigationItem.rightBarButtonItem=barbtn;
[self.tabBarController.navigationController.navigationBar setHidden:NO];

      

        
        
        
      

    

Now you need to set searchcontroller to clickme

your button method.

- (IBAction)clickme:(id)sender{
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 300, 44.0)];
searchBar.autoresizingMask =0;
searchBar.delegate = self;
searchBar.placeholder = @"Search for items...";
searchBar.showsScopeBar=YES;

UIView *searchBarWrapper = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
searchBarWrapper.autoresizingMask = 0;
[searchBarWrapper addSubview:searchBar];

self.searchItem = [[UIBarButtonItem alloc] initWithCustomView:searchBarWrapper];
self.tabBarController.navigationItem.leftBarButtonItem = self.searchItem;

self.navigationItem.rightBarButtonItem = nil;
self.navigationItem.titleView = nil;

  ////////////// ~ Search Display Controller as Object ~/////////////////////////////

self.d1 = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
self.d1.delegate = self;
self.d1.searchResultsDataSource = self;
self.d1.searchResultsDelegate = self;
self.d1.searchResultsTableView.rowHeight = 40;
self.d1.displaysSearchBarInNavigationBar = YES;
self.searchBar.translucent = NO;
self.searchBar.barTintColor = [UIColor grayColor];
self.d1.searchBar.tintColor = [UIColor blueColor];

[searchBar sizeToFit];

}

      

        
        
        
      

    

when you click the search icon
