    self.progressView.center = self.view.center;
    [self.view addSubview:self.progressView];

  self.myTimer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(updateUI:) userInfo:nil repeats:YES];


}

- (void)updateUI:(NSTimer *)timer

- (void)viewDidLoad {
    [super viewDidLoad];

    progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleDefault];
    progressView.center = self.view.center;
    [self.view addSubview:progressView];

   myTimer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(updateUI:) userInfo:nil repeats:YES];
}

- (void)updateUI:(NSTimer *)timer
{
    progressView.progress += 0.5/10;

    if ((int)progressView.progress) {

        [myTimer invalidate];

    Demoview*VC = [self.storyboard instantiateViewControllerWithIdentifier:@"Demoview"];
    [self.navigationController pushViewController:VC animated:YES];
    }
}
