I'm really new to iOS development. I wanted to add a search bar to my app. When touching on the search bar key board pops up. But when I press the search button it doesn't dismiss the keyboard. My controller .h file is as belows.

C#

@interface SearchViewController : 
UIViewController<UITableViewDelegate,UITableViewDataSource,UISearchBarDelegate>{
    
    IBOutlet UISearchBar *searchBar;
    IBOutlet UITableView *tableView;
    NSMutableArray *listOfItems;
    NSMutableArray *copyListOfItems;
    NSArray *songs;
    BOOL searching;
    BOOL letUserSelectRow;
}
@property(strong,nonatomic)NSArray *songs;
@property(strong,nonatomic)UITableView *tableView;   
@property(strong,nonatomic)UISearchBar *searchBar;
@end

I have implemented the following methods in .m file. But they don't invoke.

C#

-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{
     NSLog(@"search clicked");
    [self.searchBar resignFirstResponder];
}

-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{
    NSLog(@"Cancel Clicked");
}

Can anybody explain me the reason?

Hi,
I don't see any reference to a UIButton class or IBOutlet linked to the search button or an IBAction method that will capture the button click event.
I think you will find the following link useful:

If you still have problems after going through the article in above link, just put a shout :)

in .h file add delegate and initialize declare

Objective-C

@interface RestaurantViewController : UIViewController <uisearchdisplaydelegate,>

    UISearchDisplayController      *resName_search;
    UISearchBar *mySearchBar;

in .m file

Objective-C

    mySearchBar = [[UISearchBar alloc]init];
    [mySearchBar setDelegate:self];
//    [mySearchBar setShowsCancelButton:YES animated:NO];
    resName_search = [[UISearchDisplayController alloc] initWithSearchBar:mySearchBar contentsController:self];
    resName_search.delegate = self;
    resName_search.searchResultsDataSource = self;
    resName_search.searchResultsDelegate = self;
    [self.view addSubview:resName_search.searchBar];
   [resName_search.searchBar setFrame:CGRectMake(0.0, barOriginY+79.0, 106.0, 40.0)];

-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
{
NSLog(@" enter text clicked");

    return YES;
}
-(BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar
{

 NSLog(@"cancel clicked");
   return YES;

}
