ScrollView not working programmatically

Jest I tried programmatically ScrollView. It's working nice in ViewController.m I tried like this 

scroll=[[UIScrollView alloc]init];
    scroll.frame=CGRectMake(0, 50, self.view.frame.size.width, self.view.frame.size.height);
    scroll.delegate=self;
    scroll.scrollEnabled=YES;
    scroll.contentSize =CGSizeMake(100, 525);
    scroll.backgroundColor=[UIColor yellowColor];
    [self.view addSubview:scroll];

    goo=[[UIButton alloc]init];
    goo.frame=CGRectMake(0, 50, 100, 100);
    goo.backgroundColor= [UIColor brownColor];
    [goo setTitle:@"good Day" forState:UIControlStateNormal];
    [goo addTarget:self action:@selector(ok:) forControlEvents:UIControlEventTouchDown];
    [scroll addSubview:goo];

Working Nice but same code is not working in SecondViewControl

-(void)ok:(id)sender
{
     Second *second=[[Second alloc]initWithNibName:nil bundle:nil];
     [second setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
    [self presentViewController:second animated:YES completion:nil];

}

Second.m

scroll=[[UIScrollView alloc]init];
        scroll.frame=CGRectMake(0, 50, self.view.frame.size.width, self.view.frame.size.height);
        scroll.delegate=self;
        scroll.scrollEnabled=YES;
        scroll.contentSize =CGSizeMake(100, 525);
        scroll.backgroundColor=[UIColor yellowColor];
        [self.view addSubview:scroll];

I don't understand why scrollView not working in Second.m but same code working on ViewControl.m.My Xcode Version 6.0.1

Check the Following Steps:

  1. Do you conform to UIScrollViewDelegate in your second class.

  2. If not set , the code scroll.delegate=self; will cause problem.

Please use presentViewController instead of modalViewController and set the Delegate of UIScrollView to SecondViewController
