我有一個tableview,每個單元格包含另一個水平滾動的tableview。主桌面視圖只有6個單元高,所以最初我沒有重複使用單元格,雖然垂直滾動是波濤洶涌,所以我決定重用單元格。在垂直tableview中有3種不同類型的水平單元格。 2種類型工作得很好。 1類型正在複製。我在這裏展示的圖希望解釋這更好:在某些情況下重複使用的UITableViewCells
Vertical TableView
Row 0 Cell type A
Row 1 Cell type B
Row 2 Cell type C
Row 3 Cell type C
Row 4 Cell type C
Row 5 Cell type B
Row 6 Cell type C
他們都正確顯示,除了一些原因,在第6行顯示的數據是一樣的在第二行顯示的數據顯然有其他行是是C型,但只有2-6個是重複的。我檢查了數據數組,並將正確的數據傳遞給該行。此外,當我滾動第6行,並上移到第2行時,它也滾動到相同的索引。當我關閉重用單元格時,此問題消失,但滾動並不平滑。這是有問題的單元格類型的tableview代碼。
