Swift AutoLayout: UITextViews inside UIScrollView headache

votes

I'm trying to wrap my head around how UIScrollViews work and while there are already some pretty good answers, they don't seem to cover UITextViews, so I was wondering if anyone could tell me more about what UITextViews require to work in a UIScrollView. My setup looks like the image below and I'm getting errors that the ScrollView has no height or width constraints.

If you could, I'd appreciate it if you could elaborate a little on why this doesn't work and what requirements TextViews have when placed inside ScrollViews.

Hi can you share this storyboard with us, it would be easier to detect what actually is wrong, but for a start try to remove "Scrolling Enabled" checkmark from UITextView in Attributes Inspector – Andrew
Hey @Andrew isScrollable is disabled on the textviews. You can see the full storyboard here: dropbox.com/s/g7q1lbj0pxx14jh/Main.storyboard?dl=0 – CristianMoisei

So https://www.dropbox.com/s/gujry7ngziaipm7/Main.storyboard?dl=0 here is the fixed variant. I found a few errors:

  1. Top constraint from Title Input was to view from another hierarchy

  2. Content View - your root view in UIScrollView was without x, y constraints, so I added trailing, bottom, top and leading constraint.

And maybe some tips:

  • Your constraint should be relative to each other, so you have no need to offset all views from Safe Layout.

  • Try to separate your viewControllers to different Storyboard files, otherwise if you would work in team, it would be a real headache to fix merge problems in git)

Hope it will helps you in your project)
