UITextView not visible on UIScrollView

Question

Ok, so what I have is a UIScrollView that is constrained to all four sides of the main view, centered both vertically and horizontally, and set to have equal width and heigh

Answer 1

Avoid putting all your subviews directly inside the scrollView. The autolayout will break apart. You need to :

• Add a UIView inside the UIScrollView, with constraints 0-0-0-0 to leading-top-bottom-trailing to the UIScrollView, and put all your subViews inside that UIView.

After that, you need to set the contentSize of your UIScrollView by code.

Also, you can:

• add missing constraints to see what is missing.

• The left panel in UIStoryBoard (Document Outline), you can press the red arrow showing up to see what is missing or conflicting.
