Scroll down and up in UIScrollVIew Objective C - ios

Question

I want to scroll up and down in my page without using AutoLayout in Xcode. How do I make the scrolling work?
I want to show the second question label and text and add other labels and fields. But I can't scroll to see how they look after building the project
This is the viewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIImage *bg = [UIImage imageNamed:#"logo2.jpg"];
self.myImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
self.myImageView.image = bg;

At first glance, scrolling may not be enabled because you have not set the contentSize property of the scroll view. To set allow scrolling, the contentSize needs to be set to be larger than the frame of the scroll view.
An example in objective-c would be:
self.myScrollView.contentSize = CGSizeMake(self.myScrollView.frame.size.width + 20, self.myScrollView.frame.size.height + 20);
Updated for edited question
Any views you want to be scrollable within your scroll view need to be added as a subview on the scrollView i.e
[self.myScrollView addSubview: myLabel]; //do for all views that you want to be scrollable in the scrollView
Then you need find the sum height of all the views contained in your scroll view i.e
CGFloat sumHeight = myLabel1.frame.size.height + myView2.frame.size.height; //etc do for all views you want in your scrollView
then set it to be your contentSize ie
self.myScrollView.contentSize = CGSizeMake(self.myScrollView.frame.size.width, sumHeight);
