How to use UISearchBar with TableView in iOS

If we have a huge list of items and want to search a item from the list then we use the UISearchBar with TableView and the item will be displayed in the table which have the matching value with the search text .

Here are the steps:

Step1: Add UITableView to the main.storyboard.
Step2: set the delegate and dataSource for the tableView
Step3: Create the outlet fot tableView with following Syntax __weak IBOutlet UITableView *myTableView;
Step 4: add the UISearchBar to main.storyboard.
Step 5:set the delegate for the searchBar.
Step 5: map the myTableView with TableView.

ViewController.h

#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
{
    __weak IBOutlet UITableView *myTableView;

 NSMutableArray *stateArray;
    NSMutableArray *tempArray;

    }
@end

ViewController.m

#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    stateArray = [[NSMutableArray alloc]initWithObjects:@"Rajasthan", @"Uttar Pradesh", @"Uttarakhand",@"West Bengal",@"Tamil Nadu",@"Sikkim",@"Gujarat",@"Haryana",@"Himachal Pradesh",@"Karnataka", nil];

    tempArray = [[NSMutableArray alloc]init];

    for (id object in stateArray) {

        [tempArray addObject:object];
    }

}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - TableMethods

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{

    return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

    return [tempArray count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    NSString *cellIdentifier = @"MyTableCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if (cell == nil) {

        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }
    cell.textLabel.text = [tempArray objectAtIndex:indexPath.row];
    return cell;

}

# pragma Delegate

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
 //called when text starts editing
{
    NSLog(@"Editing bigin\n\n");

}

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{

    [tempArray removeAllObjects];

    if (searchText.length) {

        for (NSString *string in stateArray) {


      NSRange range = [string rangeOfString:searchText options:NSCaseInsensitiveSearch];

            if (range.length) {

                [tempArray addObject:string];

            }
        }

    }
    else{

        [tempArray addObjectsFromArray:stateArray];
    }
   [myTableView reloadData];

}
