tab bar가 scroll view의 밑부분을 가리는 문제를 해결하는 방법

https://stackoverflow.com/a/19325718/3151712

약간의 문제가 코드에 있어서 수정했다.

let adjustForTabbarInsets:UIEdgeInsets = UIEdgeInsetsMake(0, 0, (self.tabBarController?.tabBar.frame)!.height, 0);

self.scrollView.contentInset = adjustForTabbarInsets;

self.scrollView.scrollIndicatorInsets = adjustForTabbarInsets;

UIScrollView black screen 문제

scrollview 내부에 auto layout 이 사용된경우

( storyboard를 이용하거나 programmatically 하거나 )에는 scrollview에도 auto layout을 적용해야 한다. 그렇지 않으면 black screen만 나오는 경우가 생긴다.

scroll view 사용이 기본예시

Two things.

1. Add the labels to scroll view, not your view

You want your label to scroll with scroll view, then you should not add it on your view. When running your code, you can scroll but the fixed label there is pinned to your view, not on your scroll view

2. Make sure you added your constraints correctly

Try it on your storyboard about what combination of constraint is enough for a view. At least 4 constraints are needed for a label.

Bottom line

Here is a modified version of your code. For constraint I added padding left, padding top, width and height and it works. My code is

let labelOne: UILabel = { let label = UILabel() label.text = "Scroll Top" label.backgroundColor = .red label.translatesAutoresizingMaskIntoConstraints = false return label }() let labelTwo: UILabel = { let label = UILabel() label.text = "Scroll Bottom" label.backgroundColor = .green label.translatesAutoresizingMaskIntoConstraints = false return label }() override func viewDidLoad() { super.viewDidLoad() let screensize: CGRect = UIScreen.main.bounds let screenWidth = screensize.width let screenHeight = screensize.height var scrollView: UIScrollView! scrollView = UIScrollView(frame: CGRect(x: 0, y: 120, width: screenWidth, height: screenHeight)) scrollView.addSubview(labelTwo) NSLayoutConstraint(item: labelTwo, attribute: .leading, relatedBy: .equal, toItem: scrollView, attribute: .leadingMargin, multiplier: 1, constant: 10).isActive = true NSLayoutConstraint(item: labelTwo, attribute: .width, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute, multiplier: 1, constant: 200).isActive = true NSLayoutConstraint(item: labelTwo, attribute: .top, relatedBy: .equal, toItem: scrollView, attribute: .topMargin, multiplier: 1, constant: 10).isActive = true NSLayoutConstraint(item: labelTwo, attribute: .height, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute, multiplier: 1, constant: 30).isActive = true scrollView.contentSize = CGSize(width: screenWidth, height: 2000) view.addSubview(scrollView) }

And the scroll view looks like this
