SWRevealViewController单元显示空白，直到单击

Question

我正在使用SWRevealViewController，当我创建单元格并运行应用程序时，侧面菜单显示空白。然而，一旦你点击其中一个单元格，单元格就会出现。当您点击它时，顶部较大的单元格仍然不会显示。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switch语句以外的任何提示或其他方法都会有所帮助。提前致谢。

问题是，当你进入任何开关柜和出列cell时，已经有另一个单元在defCell出列。我过去遇到过麻烦。我不知道为什么，但由于某种原因，它搅乱了tableView。解决它的方法之一是做这样的事情

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 
    } 
} 

正如你所看到的，使用这种方法，绝不会有在同一时间
