code for implimenting search bar

{


    filteredstring =[[NSMutableArray alloc]init];

    for (NSString *str in totalstring )
    {

     NSRange stringrange =[str rangeOfString:searchText options:NSCaseInsensitiveSearch];

        if(stringrange.location!= NSNotFound)
        {
            [filteredstring addObject:str];
        }
    }
}
[tableView reloadData];

code for table view

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

if (cell == nil)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier];
}
if (tableView == self.searchDisplayController.searchResultsTableView)
{
    cell.textLabel.text = [searchResultsArray objectAtIndex:indexPath.row];
} else
{
    UIFont *myfont=[UIFont fontWithName:@"Arial" size:35];
    cell.textLabel.text = [contactNameSplitDisplayArray objectAtIndex:indexPath.row];
    cell.detailTextLabel.text=[relationTypeSplitDisplayArray objectAtIndex:indexPath.row];
    cell.textLabel.font=myfont;
}
return cell;

How can i implement search bar in table view for contacts in story board ?I am new to iOS ? and how to implement plus button and dots button within the table view?

Devi my complete answer.It works perfectly.I use search bar.Also use that delegate methods.

ViewController.h

#import <UIKit/UIKit.h>
#import <Contacts/Contacts.h> //Must import contact framework 

@interface ViewController :  UIViewController<UISearchBarDelegate,UITableViewDataSource,UITableViewDelegate>
@property (strong, nonatomic) IBOutlet UISearchBar *searchbarContacts;
@property (strong, nonatomic) IBOutlet UITableView *tableViewContactData;
@end

ViewController.m

#import "ViewController.h"

@interface ViewController ()
{
  NSMutableArray *arrayTableData;
  NSMutableArray *arraySearchContactData;
}

@end

@implementation ViewController

@synthesize tableViewContactData;

@synthesize searchbarContacts;


- (void)viewDidLoad 
{
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.
  arrayTableData = [[NSMutableArray alloc]init];
  arraySearchContactData = [[NSMutableArray alloc]init];
  [self fetchContactsandAuthorization];
  [tableViewContactData registerClass:[UITableViewCell class] forCellReuseIdentifier:@"cell"];
  [self.view addSubview:tableViewContactData];
}

//Fetching Contact and Authorization access

-(void)fetchContactsandAuthorization
{
  // Request authorization to Contacts
  CNContactStore *store = [[CNContactStore alloc] init];
  [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
    if (granted == YES) {
        //keys with fetching properties
        NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
        NSString *containerId = store.defaultContainerIdentifier;
        NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
        NSError *error;
        NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
