Tableview with Search Bar? - ios

Question

I have been trying to implement a UISearchBar to filter(search) my UITableView since yesterday but no luck.
I added my UISearchBar to my header file like this:
#import <UIKit/UIKit.h>
#interface TableViewController : UITableViewController<UISearchBarDelegate>{
}
#property (weak, nonatomic) IBOutlet UITableView *TableView;
#property (weak, nonatomic) IBOutlet UISearchBar *mySearchBar;
#property (nonatomic, strong) NSMutableArray *filteredsarkilar;
#property BOOL isFiltered;
#end
I made my UITableView's datasource a NSDictionary with indexes and sections which include titles and subtitles. It works exactly the way I want. Here is the implementation file which I have already tried to implement the search function. And by the way when I press search button the keyboard does not dismiss, why?
#import "TableViewController.h"
#import "DetailViewController.h"
#interface TableViewController (){
NSDictionary *sarkilar;
NSArray *sarkilarSectionTitles;
NSArray *sarkilarIndexTitles;
}
#end
#implementation TableViewController
#synthesize mySearchBar, filteredsarkilar, isFiltered;
- (void)viewDidLoad {
[super viewDidLoad];
UIBarButtonItem *newButton = [[UIBarButtonItem alloc] initWithTitle:#"" style:UIBarButtonItemStylePlain target:nil action:nil];
[[self navigationItem] setBackBarButtonItem:newButton];
sarkilar = #{
#"A" : #[#{#"title":#"Alayına İsyan",#"subtitle":#"Seslendiren: Mustafa Sandal"},
#{#"title":#"Ardindan",#"subtitle":#"Seslendiren: Sinasi Gurel"}],
#"B" : #[#{#"title":#"Birak Gitsin",#"subtitle":#"Seslendiren: Tarkan"},
#{#"title":#"Buralar",#"subtitle":#"Seslendiren: Duman"}],
#"C" : #[#{#"title":#"Cephaneler",#"subtitle":#"Seslendiren: Burak Kut"},
#{#"title":#"Cari Acik",#"subtitle":#"Seslendiren: Kristal"}],
};
sarkilarSectionTitles = [[sarkilar allKeys] sortedArrayUsingSelector:#selector(localizedCaseInsensitiveCompare:)];
sarkilarIndexTitles = #[#"A", #"B", #"C",#"Ç", #"D", #"E", #"F", #"G", #"H", #"I",#"İ", #"J", #"K", #"L", #"M", #"N", #"O", #"Ö", #"P", #"R", #"S",#"Ş", #"T", #"U",#"Ü", #"V", #"Y", #"Z"];

Please help me if you can, because I've been pulling my hair off my head!! Thank you
