试试这个我希望它对你有所帮助!!!

在viewcontroller.m文件中

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    myData = [[NSMutableArray alloc]init];
    myData = [[NSMutableArray alloc]initWithObjects:@"india",@"Japan",@"pakistan",@"srilanka", nil];
    _mytableView.delegate = self;
    _mytableView.dataSource = self;
}

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

-(void)viewWillAppear:(BOOL)animated
{
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(receivedNotification:)name:@"NOTIFICATION" object:nil];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return myData.count;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *const identifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

    cell.textLabel.text = [myData objectAtIndex:indexPath.row];

    return cell;
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSDictionary * dict =[NSDictionary dictionaryWithObject:@"Ravi" forKey:@"name"];
    [[NSNotificationCenter defaultCenter] postNotificationName:@"NOTIFICATION" object:nil userInfo:dict];
}


-(void) receivedNotification:(NSNotification*) notification {
