Swift CollectionView dan TableView di ScrollView

Question

Jadi, bagaimana Anda bisa melihat di gambar di bawah ini, saya memiliki collectionView dan TableView di ScrollView. Dan itu bekerja tidak seperti yang saya harapkan. Anda bisa melihat masalahnya di gambar gif. CollectionView memiliki static height = 100 dan tableview memiliki selfsizeble height. Tinggi dan lebar StackView sama dengan tinggi dan lebar ScrollView. Sepertinya ada kesalahan kecil di suatu tempat, tetapi saya tidak dapat menemukannya.

di sini AutoSizeClass untuk TableView:

class AutoSizingTableView: UITableView {
    
      override var intrinsicContentSize: CGSize {
          self.layoutIfNeeded()
          return CGSize(width: UIView.noIntrinsicMetric, height: contentSize.height)
      }
      
      override var contentSize: CGSize {
          didSet{
              self.invalidateIntrinsicContentSize()
          }
      }
      
      override func reloadData() {
          super.reloadData()
          self.invalidateIntrinsicContentSize()
      }
    
  }

Masalahnya adalah Tampilan dengan Tampilan Koleksi tetap di tempat yang sama dan tidak menggulir ke atas.

Answer 1

Berdasarkan komentar Anda "dengan menonaktifkan pengguliran dalam tampilan tabel, tidak dapat digulir sama sekali" ... Anda telah melakukan kesalahan dengan penyiapan Anda.

Berikut adalah cara mengaturnya di Storyboard agar berfungsi. Perhatikan bahwa tampilan tabel harus menonaktifkan pengguliran :

Inilah sumber Storyboard itu:
