SWRevealViewController 单元格显示为空白，直到单击

Question

我正在使用 SWRevealViewController，当我创建单元格和运行应用程序时，侧面菜单显示为空白。但是，一旦您单击其中一个单元格，该单元格就会出现。但是，当您单击它时，顶部较大的单元格仍然不会出现。这是我的代码。

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return menuTitle.count+3
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
   let index = indexPath.row
    var defCell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as UITableViewCell
    switch (index) {
        case 0:
            let cell = tableView.dequeueReusableCell(withIdentifier: "profileCell") as! profileCell
            cell.nameLbl.text = "Name Here"   //need to pull name from the database here
            cell.profileImg.image = UIImage(named: "face")! //pull from db
            print(cell)
            return cell
        case 1:
            let cell = tableView.dequeueReusableCell(withIdentifier: "labelCell") as! labelCell
            cell.menuLabel.text = "For Sale"
            return cell
        case 2,3,4:
            let cell = tableView.dequeueReusableCell(withIdentifier: "titleCells") as! titleCells
            cell.cellImg.image = iconImg[indexPath.row - 2]
            cell.cellName.text! = menuTitle[indexPath.row - 2]
            return cell
        case 5:
            let cell = tableView.dequeueReusableCell(withIdentifier: "labelCell") as! labelCell
            cell.menuLabel.text = "Profile"
            //labelCell.darkLine //cahnge line color to orange
            return cell
        case 6,7,8,9,10,11:
            print(indexPath.row)
            let cell = tableView.dequeueReusableCell(withIdentifier: "titleCells") as! titleCells
            cell.cellImg.image = iconImg[indexPath.row - 3]
            cell.cellName.text! = menuTitle[indexPath.row - 3]
            print(menuTitle[indexPath.row - 3])
            return cell
        case 12:
            //change line color
            let cell = tableView.dequeueReusableCell(withIdentifier: "titleCells") as! titleCells
            cell.cellImg.image = iconImg[indexPath.row - 3]
            cell.cellName.text! = menuTitle[indexPath.row - 3]
            return cell
        case 13:
            let cell = tableView.dequeueReusableCell(withIdentifier: "titleCells") as! titleCells
            cell.cellImg.image = iconImg[indexPath.row - 3]
            cell.cellName.text! = menuTitle[indexPath.row - 3]
            return cell
        default:
            return defCell

    }

除了 switch 语句之外的任何提示或不同方法都会有所帮助。提前致谢。

问题是，当您进入任何 switch case 并出列 cell 时，已经有另一个单元在 defCell 中出列。我过去遇到过麻烦。我不知道为什么，但出于某种原因，它弄乱了 tableView。解决它的一种方法是做这样的事情

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if indexPath.row == 0 {
        let cell = tableView.dequeueReusableCell(withIdentifier: "profileCell") as! profileCell
        cell.nameLbl.text = "Name Here"   //need to pull name from the database here
        cell.profileImg.image = UIImage(named: "face")! //pull from db
        print(cell)
        return cell
    } else if indexPath.row == 1 || indexPath.row == 5 {
        let cell = tableView.dequeueReusableCell(withIdentifier: "labelCell") as! labelCell
        if indexPath.row == 1 {
            cell.menuLabel.text = "For Sale"
        } else {
            cell.menuLabel.text = "Profile"
        }
        return cell
    } else {
        let cell = tableView.dequeueReusableCell(withIdentifier: "titleCells") as! titleCells
        if indexPath.row <= 4 {
            cell.cellImg.image = iconImg[indexPath.row - 2]
            cell.cellName.text! = menuTitle[indexPath.row - 2]
        } else {
            cell.cellImg.image = iconImg[indexPath.row - 3]
            cell.cellName.text! = menuTitle[indexPath.row - 3]
        }
        return cell
    }
}

如您所见，使用这种方法，一次出队的信元永远不会超过一个
