iOS: Best way to make a UIScrollView with dynamic height?

Question

I\'m currently setting up a UIScrollView with the following structure

UIScrollView
--ContentView (UIView)
  --ContainerView1 (UIView)
     --UILabel1
     --UILa         


        

Answer 1

//use the below code to set the content size of a scroll view.

    float newHeight=0.0f;
        for(UIView *subViews in [scrollViewObj subviews])
        {
            if([subViews isKindOfClass:[UIView class]])
            {
                newHeight=newHeight+(subViews.frame.origin.x+subViews.frame.size.height);
            }
        }
        NSLog(@"%f",newHeight);
        [scrollView setContentSize:CGSizeMake(300, newHeight)];//change the width as you need

Answer 2

//i have added code for dynamically adding the subview heights

float newHeight=0.0f;
    for(UIView *subViews in [scrollViewObj subviews])
    {
        if([subViews isKindOfClass:[UIView class]])
        {
            if([[subViews subviews] count]>0)
            {
                float heightOfSubviews=0.0f;
                for(UIView *insideSubViews in [subViews subviews])
                {
                    heightOfSubviews=heightOfSubviews+(insideSubViews.frame.origin.y+insideSubViews.frame.size.height);
                }
                NSLog(@"%f",heightOfSubviews);
                [subViews setFrame:CGRectMake(subViews.frame.origin.x, subViews.frame.origin.y, subViews.frame.size.width, heightOfSubviews)];
            }

        }
    }
    UIView *viewLastObj=scrollViewObj.subviews.lastObject;
    newHeight=viewLastObj.frame.origin.y+viewLastObj.frame.size.height;
    NSLog(@"%f",newHeight);
    [scrollViewObj setContentSize:CGSizeMake(300, newHeight)];
