Need Help in applying constraints to UIScrollView

Question

I'm adding subviews programmatically. Requirement : when extra views are added the scroll should be enabled. The constraints that I applied :

To remove extra spaces at the top I wrote self.automaticallyAdjustsScrollViewInsets = false also give content size as self.scrollView.contentSize = CGSize(width: self.contentView.frame.width, height: self.contentView.frame.height*2)

But the when the view is loaded scroll is completely disabled.

Please help me

When you using auto layout, you have to set content size at viewcontroller method, you have to override following method.

-(void)viewWillLayoutSubviews;

swift

override func viewWillLayoutSubviews() {

    }
