我的UITableView有2個定製單元：小區1小區2 &的UITableViewCell重排序控制表時滾動消失
我的UITableView顯示的一個或另一個根據枚舉值。
如果enumValue == 0，小區1所示，並表不應該允許重新排序 如果enumValue> 0，顯示小區2和表應該允許重新排序
所有這一切工作正常。重排序控件在枚舉值更改時適當地顯示。
我的問題：當重排序控件出現在單元格上時，當行滾動出視圖時它們將消失。這是爲什麼發生？
對不起，關於格式和粗略的代碼。我沒有問題的網站。任何明顯突出的東西都可能導致這種情況？

經過進一步測試，我認爲這是一個iOS 8測試版問題。 –
我也面臨同樣的問題。我傾向於相信它與iOS 8測試版的問題。 – cybervedaa
