Tableview按鈕選擇錯誤搜索後

Question

我有一個UIButton在UITableViewCell。當點擊一個UIButton時，我在數組中保存了tapped button標籤。因此，當我在UITableView內使用UISearchController進行搜索時，我得到了所需的輸出，但是在錯誤的單元格中選擇了所選按鈕。

產品圖1 - 按鈕選擇和搜索

PIC 2前 - 搜索

在PIC 1之後，我已經選擇屬於按鈕 「房間1」 ，但在搜索後，如圖2所示，輸出是正確的，但不應選擇按鈕。如何解決這個問題？

由於實現代碼如下細胞在這裏重用你需要有一個條件，檢查是否存在條件是true然後選擇按鈕，否則按鈕是正常的，所以當下一次單元要重用時，它將根據數組數據顯示正確。請檢查您的狀態tableView cellForRow method

if yourArray.count > 0 { 
    //check your array and set cell's button selection as per id or tag 
} 
else { 
    //set all cells all the button unselected 
}
