Use Xib with Scroll View - Swift
0
I try to use Xib files with UIScrollView. I set the constraints (top ,bottom ,leading ,trailing . equal width and height (priority 250)).
I added the xibs to view that inside of UIScrollView. And set the last element bottom anchor with greaterThanOrEqualTo .
But scrollview not scroll . Where is the problem ?
Thanks in advance.

I try to use Xib files with UIScrollView. I set the constraints (top ,bottom ,leading ,trailing . equal width and height (priority 250)).
I added the xibs to view that inside of UIScrollView. And set the last element bottom anchor with greaterThanOrEqualTo .
But scrollview not scroll . Where is the problem ?
Thanks in advance.

Firstly, I strongly urge you to set up all your UI in XIBs/storyboards. It's so much easier to see what you're doing, rather than adding views programmatically.
If a scroll view doesn't scroll it probably means that its contentSize is smaller than its frame. It could also mean that you're blocking touches to it, which may be caused by your UICollectionView. Embedding a scrollable view inside a scrollable view will cause you headaches.
If you want to properly set up scroll views using autolayout I recommend following this article. The core principle is:
- Add the scroll view to the VC's view and set its constraints to match the edges (leading/trailing/top/bottom) of the safe area.
- Add a content view (
UIView) whose constraints match the edges of the scroll view. - Set the content view's
widthto match thesafeArea'swidth(assuming you want vertical scrolling, otherwise match theheights). - Add all your views to the content view and ensure that their constraints provide it with a fixed height (again, assuming you're going for vertical scrolling). That means having at least 1 view with a constraint to the top of the content view, and at least 1 with a constraint to its bottom, with set heights and vertical spaces in between.
It takes a while to learn how to do this properly, so be patient.

Thanks for repyly. I also applied all topics. But I didnt set contentsize because I give the last element constraint "greaterThanOrEqualTo" so I think no need the content size.

Unfortunately you can't have any>=heights if you want the scroll view to know the content size. If you really must have that then maybe set the content view height to match the safe area height, but then it kinda defeats the purpose of the scroll view...

Firstly, I strongly urge you to set up all your UI in XIBs/storyboards. It's so much easier to see what you're doing, rather than adding views programmatically.
If a scroll view doesn't scroll it probably means that its contentSize is smaller than its frame. It could also mean that you're blocking touches to it, which may be caused by your UICollectionView. Embedding a scrollable view inside a scrollable view will cause you headaches.
If you want to properly set up scroll views using autolayout I recommend following this article. The core principle is:
- Add the scroll view to the VC's view and set its constraints to match the edges (leading/trailing/top/bottom) of the safe area.
- Add a content view (
UIView) whose constraints match the edges of the scroll view. - Set the content view's
widthto match thesafeArea'swidth(assuming you want vertical scrolling, otherwise match theheights). - Add all your views to the content view and ensure that their constraints provide it with a fixed height (again, assuming you're going for vertical scrolling). That means having at least 1 view with a constraint to the top of the content view, and at least 1 with a constraint to its bottom, with set heights and vertical spaces in between.
It takes a while to learn how to do this properly, so be patient.

Thanks for repyly. I also applied all topics. But I didnt set contentsize because I give the last element constraint "greaterThanOrEqualTo" so I think no need the content size.

Unfortunately you can't have any>=heights if you want the scroll view to know the content size. If you really must have that then maybe set the content view height to match the safe area height, but then it kinda defeats the purpose of the scroll view...
