- (void)viewDidLoad {
   UIButton* button_write = [[UIButton alloc]init];
    button_write.backgroundColor = [UIColor redColor];
    button_write.frame = CGRectMake(0, 80, 130, 25);
    button_write.layer.cornerRadius = 10;
    [button_write addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button_write];
}
- (void)buttonAction:(id)sender {
    KKKKViewController *samplePopupViewController = [[KKKKViewController alloc] initWithNibName:@"KKKKViewController" bundle:nil];
    samplePopupViewController.delegate = self;

    [self presentViewController:samplePopupViewController animated:YES completion:nil];
}
-(void)dismissPopupJK
