Ios UIView未舍入，UITableView单元格回收

我在UITableView的单元格中有一个UIView。我的cellForRowAtIndexPath环绕了该视图。当我打开viewcontroller并看到表格时，所有可见视图都是四舍五入的。但是，当我向下滚动时，显示的第一个新单元格没有圆形视图。我怎么修理它

我的cellforrowatinex如下所示：

let cell = tableView.dequeueReusableCell(withIdentifier: "RepeatingCell", for: indexPath) as! CustomTableViewCell
cell.delegate = self
tableView.contentInset = UIEdgeInsetsMake(10, 0, 0, 0)

if (indexPath as NSIndexPath).row < tableListInfo_Context.count {
    let task = tableListInfo_Context[(indexPath as NSIndexPath).row                
    let accState = task.value(forKey: "state") as? String
    //Removed assigning labels their text
    let mainView = cell.mainView
    mainView.isHidden = false
    let circleView = cell.viewToRound
    circleView?.isHidden = false
    circleView?.layer.cornerRadius = (circleView?.frame.size.width)!/2
    circleView?.layer.masksToBounds = true           
    cell.layoutMargins = UIEdgeInsetsMake(0, 1000, 0, 1000)
} else {
    //My last cell hides several views to reveal a view under them 
    //If I comment this one line out, I get the not-rounded problem only once and it does not show up again even if I continue scrolling up / down 
    let mainView = cell.mainView
    mainView.isHidden = true
    let circleView = cell.viewToRound
    circleView?.isHidden = true
}

然而，这并没有解决问题。这是多么不一致，令人沮丧。任何帮助都将不胜感激

邓肯要求的完整代码：

不要在

单元格中设置视图的图层属性，而是在
CustomTableViewCell
类中设置它们。您可以在
awakeFromNib
方法中设置它们

简而言之，将下面的代码移动到
awakeFromNib

 let circleView = cell.viewToRound
    circleView?.layer.cornerRadius = (circleView?.frame.size.width)!/2
    circleView?.layer.masksToBounds = true  

sudo代码可以是这样的：

awakeFromNib(){
self.viewToRound?.layer.cornerRadius = (viewToRound?.frame.size.width)!/2
viewToRound?.layer.masksToBounds = true  

}

self.viewToRound?.layer.cornerRadius = (viewToRound?.frame.size.width)!/2
viewToRound?.layer.masksToBounds = true  

}

试试这个，它会有用的

override func awakeFromNib() {
        super.awakeFromNib()
        self.viewToRound?.layer.cornerRadius = (viewToRound?.frame.size.width)!/2
        viewToRound?.layer.masksToBounds = true 
    }


override func prepareForReuse() {
        super.prepareForReuse()
        self.viewToRound?.layer.cornerRadius = (viewToRound?.frame.size.width)!/2
        viewToRound?.layer.masksToBounds = true 
    }

        self.viewToRound?.layer.cornerRadius = (viewToRound?.frame.size.width)!/2

    }

    }

@阿德尔已经在他的评论中告诉了你这个问题和解决方案

在任何情况下，您都需要完全配置单元格。记住，当你得到一个回收的电池时，它可能处于任何可能的剩余状态

在您的情况下，关键点是：

if (indexPath as NSIndexPath).row < tableListInfo_Context.count {
  //Configure cells that are not the last cell
} else {
  //Configure cells the last cell
  mainView.isHidden = true
}

@VishalSonawane的答案是好的，但要做到这一点，您应该使用两个不同的标识符，一个用于除最后一个之外的所有单元，另一个用于最后一个单元，并使用一个不同的标识符，其中一个单元预配置了mainView hidden。这样，您就不会得到回收的最后一个单元格，并尝试将其用于表视图中的其他位置。
