Bug when reloading a certain row of a UTableView-CodePudding

I have a strange bug when I reload a certain row of UITableView via the .reloadRows() method. Snippets of code:

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return news_section.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell  =   tableView.dequeueReusableCell(withIdentifier: "cell_section", for: indexPath) as! NewsSectionCell
        cell.delegate_press_btn = self
        var news_index = self.news_section[indexPath.row]
        cell.number =  news_index
        cell.indexPath = indexPath
        return cell
    }
    
    
    
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        var highCell = self.needs_high_cell(news_sect: self.news_section[indexPath.row])
        return   highCell ? 150 : 90.0
    }

The cell has a button when pressed via delegate does following:

            self.news_section[index] = 0
            self.news_table_view.reloadRows(at: [indexPath], with: .none)

Sometimes it works sometimes it produces this: NSMutableRLEArray objectAtIndex:effectiveRange:: Out of bounds

I tried to change the cell number by changing the array from where the cell gets his number. And then reload only that row.

Use this code may be helpfull for you:---

let indexPath = IndexPath(item: rowNumber, section: 0)
tableView.reloadRows(at: [indexPath], with: .top)

CodePudding user response：

For anybody looking for a similar problem :

// Reconfigures any existing cells for the rows. Reconfiguring is more efficient than reloading a row, as it does not replace the // existing cell with a new cell. Prefer reconfiguring over reloading unless you actually need an entirely new cell for the row. @available(iOS 15.0, *) open func reconfigureRows(at indexPaths: [IndexPath])
