Question

I am trying to put the Scrollview on the viewcontroller? is it possible? and i also want to put the UIView on the ScrollView.

UIScrollView *scrollView =[[UIScrollView alloc]initWithFrame:CGRectMake(20, 60, 280, 200)];
    scrollView.contentSize = CGSizeMake(280, 200);
    scrollView.backgroundColor=[UIColor orangeColor];
    scrollView.delegate = self;
    [self.view addSubview:scrollView];

    UIView *container = [[UIView alloc] initWithFrame:CGRectMake(20, 60, 280, 200)];
    container.backgroundColor = [UIColor whiteColor];
    [scrollView addSubview:container];

In this code i tried to put the scrollview on the VC and also i tried to put View on the ScrollView.

            rb1 = [[RadioButton alloc] initWithGroupId:@"first group" index:j];
            rb1.frame = CGRectMake(20,dy,22,22);
            [container addSubview:rb1];
            [rb1 release];

            label1 =[[UILabel alloc] initWithFrame:CGRectMake(50, dy, 60, 20)];
            label1.backgroundColor = [UIColor clearColor];
            label1.text = [answers objectAtIndex:j];
            [container addSubview:label1];

and here i tried to put the a radio button on View.

I hope it is clear:) Sorry my bad english.Thanks.

Answer 1

Scroll occurs when the frame of a scroll view is less than your content size.

Your frame is having size (280,200) and you have provided same size to contentSize.

To make the scroll possible replace below line into your code.

scrollView.contentSize = CGSizeMake(300, 260);
